My research is stimulated by the fascination for the collective many-body behavior of quantum particles and aims to uncover both fundamental physical phenomena and potential practical applications.
As a group leader in the department for quantum many-body theory at the Max Planck Institute for Solid State Research I focus on quantum transport in novel quantum materials. I'm particularly intrigued by the interdisciplinary importance of fractionalized states of matter which are of relevance both for quantum information theory and for strongly correlated electron systems. |
ongoing directions of research
|
Can we generalize the concept of magic angle twisted bilayer graphene to other systems? What are the universal principles behind the creation of flat bands in Dirac/Weyl semimetals in a quasiperiodic environment? What is the nature of many-body states in artificial twistronic structures?
|
|
Are there signatures of topological order in strongly correlated electron systems? How can we harness the synergies between quantum information and materials science? What are experimentally accessible signatures of fractionalization and topological order?
|
|
What is the effect of impurity scattering on the electrooptical response in Berry curved materials such as Weyl semimetals as well as topological insulators and superconductors?
|
past research interests
|
What makes iron based supercoductors superconducting? Is there a universality principle? How do they overcome the strong Coulomb repulsion? What are their topological properties?
|
|
What is the interplay of artificial gauge fields and spin-orbit coupling with the many body phases of ultracold spinor bosons?
|
|
How does disorder influence the transport properties of topological insulator surface states? Can we exploit disorder to access knowledge about the quantum behavior of topological insulator heterostructures?
