The quantum skyrmion Hall effect in f electron systems

Robert Peters, Jannis Neuhaus-Steinmetz, Thore Posske

The flow of electric current through a two-dimensional material in a magnetic field gives rise to the family of Hall effects. The quantum versions of these effects accommodate robu…

Exotic heavy fermion superconductivity in atomically thin CeCoIn films

L. Peng, M. Naritsuka, S. Akutagawa +7

We report an {\it in-situ} scanning tunneling microscopy study of atomically thin films of CeCoIn, a -wave heavy-fermion superconductor. Both hybridization and superconducti…

Non-Hermitian skin effect in equilibrium heavy-fermions

Shin Kaneshiro, Tsuneya Yoshida, Robert Peters

We demonstrate that a correlated equilibrium -electron system with time-reversal symmetry can exhibit a non-Hermitian skin effect of quasi-particles. In particula…

Quantum metric on the Brillouin Zone in correlated electron systems and its relation to topology for Chern insulators

Takahiro Kashihara, Yoshihiro Michishita, Robert Peters

Geometric aspects of physics play a crucial role in modern condensed matter physics. The quantum metric is one of these geometric quantities which defines the distance on a paramet…

Nonlinear response induced by Ferromagnetism in a Noncentrosymmetric Kondo Lattice system

Koki Shinada, Robert Peters

Recently, nonlinear responses have been actively studied in both experiments and theory. Particularly interesting are inversion-symmetry broken systems, where an even-order nonline…

Surface exceptional points in a topological Kondo insulator

Robert Peters, Kazuhiro Kimura, Yoshihiro Michishita +2

Correlated materials have appeared as an arena to study non-Hermitian effects as typically exemplified by the emergence of exceptional points. We show here that topological Kondo i…
