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…
Mott transition and magnetism in a fragile topological insulator
Ashish Joshi, Robert Peters
We study the effects of electronic correlations on fragile topology using dynamical mean-field theory. Fragile topological insulators (FTIs) offer obstruction to the formation of e…
Magnetism of magic-angle twisted bilayer graphene
Javad Vahedi, Robert Peters, Ahmed Missaoui +2
We investigate magnetic instabilities in charge-neutral twisted bilayer graphene close to so-called "magic angles" using a combination of real-space Hartree-Fock and dynamical mean…
Charge neutral fermions and magnetic field driven instability in insulating YbIrSi
Y. Sato, S. Suetsugu, T. Tominaga +12
Materials where localized magnetic moments are coupled to itinerant electrons, the so-called Kondo lattice materials, provide a very rich backdrop for strong electron correlations.…
Effects of strong correlations on the nonlinear response in Weyl-Kondo semimetals
Akira Kofuji, Yoshihiro Michishita, Robert Peters
Nonlinear responses give rise to various exciting phenomena, which are forbidden in linear responses. Among them, one of the most fascinating phenomena is the recently observed gia…
