Dislocation Non-Hermitian Skin Effect
Frank Schindler, Abhinav Prem
We demonstrate that crystal defects can act as a probe of intrinsic non-Hermitian topology. In particular, in point-gapped systems with periodic boundary conditions, a pair of disl…
Symmetry Indicators for Inversion-Symmetric Non-Hermitian Topological Band Structures
Pascal M. Vecsei, M. Michael Denner, Titus Neupert +1
We characterize non-Hermitian band structures by symmetry indicator topological invariants. Enabled by crystalline inversion symmetry, these indicators allow us to short-cut the ca…
Tutorial: Dirac Equation Perspective on Higher-Order Topological Insulators
Frank Schindler
In this tutorial, we pedagogically review recent developments in the field of non-interacting fermionic phases of matter, focussing on the low energy description of higher-order to…
Theory for the negative longitudinal magnetoresistance in the quantum limit of Kramers Weyl semimetals
Bo Wan, Frank Schindler, Ke Wang +4
Negative magnetoresistance is rare in non-magnetic materials. Recently, a negative magnetoresistance has been observed in the quantum limit of -AgSe, where only one band of…
Discovery of topological metamaterials by symmetry relaxation and smooth topological indicators
Cyrill Bösch, Tena Dubček, Frank Schindler +2
Robustness against small perturbations is a crucial feature of topological properties. This robustness is both a source of theoretical interest and a drive for technological applic…
Algorithms for Tensor Network Contraction Ordering
Frank Schindler, Adam S. Jermyn
Contracting tensor networks is often computationally demanding. Well-designed contraction sequences can dramatically reduce the contraction cost. We explore the performance of simu…
