Welcome to the Institute for Theory of Condensed Matter
The institute was founded in 1976 and today comprises four groups. In close collaboration with the Institute for Quantum Materials and Technologies (IQMT) they conduct research on a wide range of topics in contemporary condensed matter physics. Close interactions, collaborations, and joint seminars exist with our partner institute, the Institute for Theoretical Solid State Physics (TFP).
Strongly correlated electrons in low dimensional systems: frustrated quantum magnets, Kondo-effect, quantum hall- and spin liquid states
Hydrotronics - EU-funded network for research on ultra-pure materials
The investigation of electronic hydrodynamics is a central research topic of researchers at our Institute. The emergence of hydrodynamic electronics can be seen in non-local, superballistic and pre-turbulent transport of energy and electric charge. There is a growing interest in the hydrodynamic effects in interacting electron systems in ultra-pure materials. The EU-funded project HYDROTRONICS is coordinated by researchers of our institute. It brings together researchers from seven countries and three continents that work on hydrodynamic charge and energy transport in electronic systems.

Elasto-Q-Mat — DFG-funded Transregional Collaborative Research Center on Quantum Materials
Quantum materials are characterized by unusual physical properties. Elasto-Q-Mat, a Transregional Collaborative Research Center (SFB-TRR) in close cooperation between the Karlsruhe Institute of Technology (KIT), the Goethe University Frankfurt, the Johannes Gutenberg University Mainz, the Max Planck Institute of Polymer Research in Mainz, and the Max Planck Institute for Chemical Physics of Solids in Dresden will investigate quantum materials whose properties can be dramatically changed through elastic deformations.
In celebration of Professor Alexander Mirlin's 60th birthday and his outstanding contributions to the field, the TKM and the IQMT are organising a workshop on disordered and interacting systems in condensed matter physics. It will take place at the physics department of the KIT South Campus on the 3rd and 4th of November 2022.More information
Jörg Schmalian is one of the recipients of the 2022 John Bardeen Prize. He is recognized for “impactful, materials-based theoretical insights into unconventional superconductors across the periodic table including organic superconductors, cuprates, and pnictides” and “pioneering work on the effect of intertwined order as well as on a beyond-quasi-particle description of normal states for unconventional superconductivity”. The prize is awarded once every three years on the occasion of the M2S (Materials and Mechanisms of Superconductivity) conference. The other winners are Mohit Randeria (The Ohio State University) and Peter Hirschfeld (University of Florida). Congratulations!Link to prize homepage
The German Research Foundation (DFG) is funding the Transregional Collaborative Research Center Elastic Tuning and Response of Electronic Quantum Phases of Matter (ELASTO-Q-MAT) for the period July 2020 - June 2024. In cooperation with the Universities of Frankfurt and Mainz and Max Planck Institutes in Mainz and Dresden, quantum materials are investigated whose electronic properties are exceptionally sensitive to elastic deformations and strain. Open questions such as superelasticity, nematic order and fluctuations as well as critical elasticity in electronic quantum materials are being addressed. Jörg Schmalian from the Institute of Condensed Matter Theory and the Institute of Quantum Materials and Technologies (IQMT) is the local co-spokesperson of the initiative.DFG Press Release
At the conference "Recent Progress in Graphene & 2D Materials Research (RPGR 2017)" in Singapore Julia Link is awarded the "RSC Advances Poster Prize" for her poster with the title "Out-of-bounds hydrodynamics in anisotropic Dirac fluids". Congratulations!
Jörg Schmalian explains the elastic properties of critical, strongly correlated systems in the journal for the members of the German Physical Society (Physik Journal 03/2017). In those systems there is no regime where the force is proportional to the displacement.
The American Physical Society honors Igor Gornyi and Alexander Mirlin for their "outstanding service to the physics community".More information
