Isotropic 3D topological phases with broken time reversal symmetry
Helene Spring, Anton R. Akhmerov, Daniel Varjas
Axial vectors, such as current or magnetization, are commonly used order parameters in time-reversal symmetry breaking systems. These vectors also break isotropy in three dimension…
Lack of near-sightedness principle in non-Hermitian systems
Helene Spring, Viktor Könye, Anton R. Akhmerov +1
The non-Hermitian skin effect is a phenomenon in which an extensive number of states accumulates at the boundaries of a system. It has been associated to nontrivial topology, with…
Phase transitions of wave packet dynamics in disordered non-Hermitian systems
Helene Spring, Viktor Könye, Fabian A. Gerritsma +2
Disorder can localize the eigenstates of one-dimensional non-Hermitian systems, leading to an Anderson transition with a critical exponent of 1. We show that, due to the lack of en…
