Orbitronics: from Topological Matter to next Level Electronics

Workshop, July 19th - 22nd 2022

This workshop aims to boost the new field of orbitronics – a next generation device technology which utilizes the orbital current as an information carrier. The orbital current is expected to be crucial in understanding physical properties of topological matters and to interact with various orders and excitations in strongly correlated matters, which are largely unexplored as the orbitronics is in its infancy. The workshop highlights the emerging concept of the orbital current from the perspective of topology and strong correlation, which are two major pillars of contemporary condensed matter physics. The envisioned impact of the workshop is to exchange ideas and viewpoints from different disciplines of condensed matter physics: spin-orbitronics in metals, strong correlation in oxides, and topological phase in 2D materials.

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.

Ultrafast Antiferromagnetic Writing

Workshop, May 9th - 10th 2022

While recent developments in photonics enable nearly lossless data transfer with speeds exceeding 1 Tb/s, current magnetic data storage cannot keep up with these data-flow rates nor decrease energy dissipations. Consequently, already now data centres are becoming the biggest consumers of electricity world-wide. Antiferromagnets represent a highly-promising playground for the quest for the fastest and the least-dissipative mechanism of data storage. However, in thermodynamic equilibrium, the energy of interaction of a magnetic field with the antiferromagnetic Néel vector is zero. Despite the 60-year long search for thermodynamic conjugates to the antiferromagnetic order parameter, efficient means to control antiferromagnetism are still being pursued. It is the main reason that hampers applications of antiferromagnets and further development of antiferromagnetic spintronics, magnonics and data storage, in particular.
Although many experimental and theoretical studies make us believe that ultrafast writing of bits in antiferromagnets at THz rates must be possible, such an ultrafast writing has never been demonstrated in antiferromagnetic media and the highest frequency of rewriting of magnetic bits (100 GHz) belongs to ferrimagnets. The landmark of 1 THz remains to be a monumental challenge.
The goal of the workshop is to bring together experts in ultrafast switching of antiferromagnetism, review the state-of-the-art, discuss the present challenges, define short- as well as long-term goals in the field with the ultimate goal to initiate a breakthrough towards the fastest ever and least dissipative writing of magnetic bits.

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 - 27th 2022

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.
