Research Focus of the ITF

Research at the Institute for Theoretical Solid State Physics (ITF) concentrates on the theoretical aspects of condensed matter physics and materials science. 

Two pillars

The first pillar of the research program of the theorists at the ITF is theory-motivated and curiosity-driven research on condensed matter systems and quantum materials with long-term application potential. Being embedded in an experimental research environment, the second pillar is to interact with experimental colleagues concerning the interpretation and modeling of data and the development of theoretical frameworks for applications and devices. 

As partner in the DRESDENconcept and Dresden Center for Computational Materials Science (DCCMS), close ties exists between the IFW/ITF and particularly the TU Dresden, the Max Planck Institute for the Physics of Complex Systems and the Max Planck Institute Chemical Physics of Solids.

At the center of our research program is the theoretical description, calculation and modelling of electronic, magnetic and structural properties of materials. These properties directly emerge from the chemical composition and the patterns formed by the atoms at the nanoscale.

Main research directions

The main directions of the research at the ITF, which are embedded in the research structure of the IFW, focus on the following topics:

  • Quantum magnetism, intermetallic magnets and ferroic cooling (Richter, Nishimoto, Hozoi)
  • Topological states of matter (Ortix, Koepernik)
  • Unconventional superconductivity and superconducting materials (Koepernik, Drechsler, Sykora, Efremov)
  • Self-organized electronic order at the nanoscale (Roessler, Sykora)
  • Novel ground states and spin excitations in complex transition metal oxides (Hozoi, Richter, Efremov)
  • Nanoscale magnetism and skyrmionic systems (Richter, Bogdanov, Roessler)
  • Multifunctional inorganic nano-membranes (Ortix)

Methods and method development

An important aspect of the research program within the ITF is the development, application and maintenance of a numerical infrastructure dedicated to the calculation of electronic and magnetic properties of new materials and nanostructures. This infrastructure includes:

  • The FPLO package, a full-potential local-orbital minimum-basis code, developed and maintained in-house (Koepernik, Richter)
  • Ab initio quantum chemistry methods (Hozoi)
  • Many-body methods for correlated electron systems (Daghofer, Nishimoto, Sykora)
  • Several high performance computer clusters tailored to the numerical needs of the IFW Dresden (Nitzsche)
