Brenig Group, Technische Universität Braunschweig

Wolfram Brenig’s expertise is on the theory of many-body phenomena in condensed matter and emergent materials with novel collective behavior. Current focuses of his research are quantum magnets, strongly correlatedelectron systems, quantum critical matter, as well as nano- and low-dimensional systems which he studies in transition metal compounds, high-temperature and organic superconductors, supramolecular magnets, multiferroic materials and Kondo systems. More specifically, in quantum magnets Wolfram Brenig is investigating unconventional ground states of matter, quantum phase transitions and emergent elementary excitations. Regarding low-dimensional systems Wolfram Brenig has a proven research record on the theory of anomalous spin and heat transport, as well as various spectroscopies of spin-chain and ladder materials.

Wolfram Brenig’s research on strongly correlated electrons systems is centered on the renormalization of electronic dynamics, competing order and mechanisms of high-temperature superconductivity. Recently Wolfram Brenig has started to investigate (supra)molecular magnets regarding properties in high magnetic fields, spin dynamics and thermodynamic properties. Finally a substantial part of Wolfram Brenig’s research is devoted to the design of new methods to treat quantum many-body systems. He has contributed to the development of auxiliary-particle field-theories, operator-RG methods, series-expansion techniques, large scale exact diagonalization codes, and quantum Monte-Carlo simulations.
