New Spin on Molecular Quantum Materials

Workshop, May 24th - 26th 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. 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.
