Ultraquantum magnetoresistance in Kramers Weyl semimetal candidate -Ag2Se
Cheng-Long Zhang, Frank Schindler, Haiwen Liu +14
The topological semimetal -Ag2Se features a Kramers Weyl node at the origin in momentum space and a quadruplet of spinless Weyl nodes, which are annihilated by spin-orbit coupli…
Competing orders in the Hofstadter t-J model
Wei-Lin Tu, Frank Schindler, Titus Neupert +1
The Hofstadter model describes non-interacting fermions on a lattice in the presence of an external magnetic field. Motivated by the plethora of solid-state phases emerging from el…
Topolectrical circuit realization of topological corner modes
Stefan Imhof, Christian Berger, Florian Bayer +8
Quantized electric quadrupole insulators have recently been proposed as novel quantum states of matter in two spatial dimensions. Gapped otherwise, they can feature zero-dimensiona…
Higher-Order Topological Insulators
Frank Schindler, Ashley M. Cook, Maia G. Vergniory +4
Three-dimensional topological (crystalline) insulators are materials with an insulating bulk, but conducting surface states which are topologically protected by time-reversal (or s…
Probing many-body localization with neural networks
Frank Schindler, Nicolas Regnault, Titus Neupert
We show that a simple artificial neural network trained on entanglement spectra of individual states of a many-body quantum system can be used to determine the transition between a…
