Summer School: Emergent Phenomena in Quantum Many Body Systems
Workshop, September 13th - 14th and 20th - 21st 2021
Understanding the complex phases of matter which are intertwined with each other has always been on the forefront of research in condensed matter physics. However, the immensely complex nature of interacting many body systems requires specialized understanding both theoretically and experimentally, which break down the many body interactions into more tangible parts to describe the rich abundance of phenomena we observe in nature. Prominent examples include - spin density wave, charge density wave, unconventional superconductivity, topological insulators, just to name a few.
Within this summer school we aim to educate our young PhD students on a broad range of emergent phenomena within this field. Since most come from diverse backgrounds, not only having different levels of experiences with theory or state of the art experiments, but also different topics of expertise within the field of condensed matter itself, we aim to broaden their knowledge and extend their horizon with this 4 days online summer school.
Hence, the lectures given by experts in their respective fields of condensed matter, will introduce some important scientific questions and challenges of their fields, reaching both theoretical and experimental aspects of research.
Lastly, this summer school is organized as part of the SFB Transregio 288 Elasto-Q-Mat that is funded through the German Research Foundation (DFG). By organizing yearly summer schools, the Elasto-Q-Mat aims at providing the scientific foundation needed for young students to advance in their field and become future leading scientists.

Dissipative Phases of Entangled Quantum Matter
Workshop, May 3rd - 5th 2021
Driven-dissipative quantum many body systems constitute a cross- disciplinary frontier of research encompassing condensed matter, AMO and solid state physics. Many-particle systems where quantum coherent dynamics and dissipative effects occur on the same footing, find experimental realization in cavity QED, driven open Rydberg systems, trapped ions, exciton-polariton condensates, coupled micro- cavity arrays — among the others.
These platforms offer the unique opportunity to explore extensive phases of matter which cannot be encompassed through conventional statistical mechanics. At the same time they pose a number of fundamental and technical challenges. The ubiquitous intrusive effect of dissipation in experiments, confronts researchers to optimize and enhance the role of quantum fluctuations in strongly noisy and decoherent environments. At the same time, an efficient simulation of open many-particle systems require a formidable combination of techniques and expertise ranging from advanced field theoretical methods to forefront numerical techniques, from machine learning to non-unitary versions of techniques from the field of strongly correlated systems.
These 3-days workshop will bring together a number of experts from a diverse and interdisciplinary set of fields, including condensed matter physics, cold atoms, quantum engineering, quantum optics, atomic and solid state physics, with a broad selection of experimentalists from currently active fields. Ample space will be devoted to the participation of emergent and promising young scholars with dedicated flash talks in a 'March Meeting' format. Furthermore, the workshop will host two topical sessions to foster dialogue among researchers belonging to different sub-communities.

New Spin on Molecular Quantum Materials
Workshop, May 24th - 26th 2022
- To Image 1

Stabilizing fragile quantum states necessitates understanding and control of multiple material variables. Molecular quantum materials provide a test field for models and theory due to their high chemical variability, large compressibility and the possibility of systematic disorder tuning. This workshop fosters the interaction between theory and experiment, particularly addressing scientists previously not engaged in organic materials.
The recent years saw considerable advancements, but also a dichotomy between experiment and theory. For instance, the nature of quantum-spin-liquid and charge-dipole-liquid states in κ-phase BEDT-TTF salts remains controversial. On the other hand, anomalous transport in bad and strange metals near electronic instabilities awaits a solid theoretical description.
Those phenomena rely on a suppression of effective energy scales via frustration or competing orders, making molecular quantum materials susceptible to many sub-dominant factors such as magneto-elastic coupling, disorder and spin-orbit effects. To that end, the workshop will stimulate exchange among different fields, especially focusing on spin vs charge degrees of freedom, insulators vs metals, transport vs thermodynamic methods and non-equilibrium vs equilibrium probes.
This workshop is organized by SPICE as part of the Gutenberg International Conference Center (GICC) at Johannes Gutenberg University Mainz (JGU). The GICC is funded through the German Research Foundation’s (DFG) university allowance in the Excellence Strategy program and aims at fostering JGU as a national and international research hub. By organizing regular conferences and workshops in fields of excellent JGU research, the GICC provides a platform to build interest networks and collaborations – to promote exchange and dialog among academics and research groups from all over the world.

Coherent order and transport in spin-active systems: Interplay between magnetism and superconductivity
Mainz, Germany: November 17th - 19th 2020
The electron spin and its quantum nature are fundamental to the phenomena of magnetism as well as superconductivity. The exchange interaction that causes magnetic ordering is intricately related to the Fermionic antisymmetry of the electron wavefunction and thus, the Pauli exclusion principle. Conventional superconductors are devoid of a spin supercurrent due to the singlet nature of the Cooper pairs that constitute the superconducting fluid. Despite the common denominators, the two phenomena have traditionally been considered mutually exclusive and are investigated by different communities.
Recently, coherent order and spin transport in magnetically ordered insulators has been demonstrated. This phenomenon of spinsuperfluidity is similar to superconductivity in several aspects. The development of devices based on superfluidity may, hence, profit from the profound knowledge of superconductivity. At the same time, magnet/superconductor hybrids hosting spinfull Cooper pairs have been engineered. This has opened prospects for superconducting spintronic devices as well as for the realization of unconventional superconducting states. Finally, the electron-electron attraction in many of the unconventional superconductors with exotic condensates is believed to be mediated by spin fluctuations. Therefore, these three seemingly disjoint fields are intricately relying on knowledge from each other and can best be tackled with an overview picture of all three. Providing this overview and a common discussion platform is a main goal of this workshop.
The workshop shall bring together experts and young researchers from three different communities: (i) Magnetism and spintronics, (ii) Mesoscopic superconductivity, and (iii) Strongly correlated systems/mechanisms underlying superconductivity. The purview includes coherent and incoherent magnetization dynamics in conjunction with the various spintronic effects that allow its manipulation and detection. Specific emphasis will be laid on the phenomena of spinsuperfluidity and magnon condensates due to their fundamental similarity with the superconducting state. The systems where the magnetic order interacts with conventional superconductors forms an exquisite field in itself which will benefit greatly from the different communities. Finally, the case of spin-fluctuations-mediated superconductivity, that is believed to underlie a wide range of unconventional superconductors, can best be discussed with the three communities present at the workshop.

Online Young Research Leaders Group Workshop: Spin, Charge, and Heat Transport: From Symmetries to Emergent Functionalities
Mainz, Germany: November 3rd - 4th 2020
What once began with spin-polarized electric currents in ferromagnets and the giant magnetoresistance, today is an internationally overarching research field known as spintronics. The last two decades, in particular, saw the consolidation of spintronics into modern solid state research. This was possible in large parts thanks to the experimental confirmation of the spin Hall effect and its inverse counterpart that enables electrical detection of pure spin currents. By now, it is known that the electronic spin not only couples to magnetic but also electric fields as well as heat gradients, adding interconversion phenomena between spin, charge, and heat to the spintronic inventory, examples being the spin Seebeck, spin Nernst, and Edelstein effects. Being inspired by both the uncovering of fundamental physics as well as the vision that spin will serve as an information carrier, the spintronics community studied a broad range of material classes, including normal, topological, and magnetic metals as well as topological and magnetic insulators. Magnets, in particular, proved to contain a wealth of surprises, exemplified by topological magnons, topological (spin) Hall effects in skyrmion crystals, anomalous Hall effects in antiferromagnets, or the magnetic spin Hall effect.
This SPICE Young Research Leaders Group Workshop serves as a melting pot of ideas on how to tackle the major spintronic challenges of this decade. The program of this workshop is built around the following major questions:
(1) Relying on symmetry arguments, which transport phenomena do we expect?
(2) How does the topological nontriviality of the electronic or magnonic band structure influences spin, charge, and heat transport?
(3) Which materials show particularly large transport and why? (Can we engineer spin transport?)
(4) How do we perform clear-cut experiments to disentangle a particular (spin) transport phenomenon from others?
(5) How do we use the arsenal of spintronics as means to explore and characterize complex materials?

2D van der Waals Spin Systems
On-line Workshop, August 4th - 7th 2020
Layered van der Waals (vdW) materials have provided new research avenues of condensed matter physics as well as applied physics since these materials at the mono-layer limit show novel electronic, optical and topologically-protected states, which do not arise in its bulk forms.
The successful realization of 2D-layered vdW ferromagnetic materials in 2017 connected the topic of 2D vdW magnets to spintronics. This has allowed us to explore novel spintronic effects, the fundamentals physics of 2D magnetism, as well as control of magnetism by external stimuli such as electric field, current and mechanical strain.
The timely workshop address key questions such as, what is spin dynamics properties at the truly one-monolayer limit?; Can we apply the same spin transport theories to materials at the 2D limit?; What novel spintronic and magnonic phenomena belongs only to the 2D-magnets and/or multi-layers with them?
This workshop bridge across different areas of modern condensed matter physics and materials science, specifically the vast research field of 2D materials and the spintronics field that exploits spin degree of freedom in non-2D systems.

Topological Superconductivity in Quantum Materials
On-line Workshop, October 19th - 22nd 2020
Topology in quantum mechanics is applied to determine if a system is trivial or topological. A condensed matter system has a topological nature if the general wavefunction describing it is adiabatically distinct from the atomic limit. Although nontrivial topology has been known to exist in quantum Hall systems for nearly four decades, recent years have seen a massive resurgence in the interest of topological matter stemming from a series of ground-breaking discoveries. In many cases, topological quantum mechanics is achieved in systems involving superconductors with highlights including: Majorana Fermions in nanowire devices; unconventional electron pairing in layered oxides and the decoding high temperature superconductivity; superconducting thin films of strontium ruthenate; topological superconductivity in UTe2; coupling superconductivity into chiral (topological) molecules; and topological superconductivity and magnetism in twisted bilayer graphene.
The incredible progress made in materials research over the past decade and half has been central to the rapid development of unconventional superconductivity in topological quantum materials. These include the development of atomically-controlled crystals, thin films and interfaces, and the manipulation of pristine two-dimensional materials and superlattices. The widespread interest and progress in unconventional superconductivity and topology in such advanced materials continues to accelerate; however, a targeted, interdisciplinary, approach is required in order to achieve full understanding and the discovery of new science. This workshop brings together world-leading scientists from a broad range of disciplines working on overlapping themes involving correlated electrons and superconductivity in topological systems. These communities will have an opportunity to appreciate how these areas are interlinked thereby stimulating further understanding and new collaborations. The workshop is organised within the framework of the EPSRC-JSPS Core-to-Core International Network “Oxide Superspin”.
