A unique feature of non-Hermitian systems is the skin effect, which is the extreme sensitivity
to the boundary conditions. Here, we reveal that the skin effect originates from intrinsic non …

Non-Hermiticity enriches topological phases beyond the existing Hermitian framework.
Whereas their unusual features with no Hermitian counterparts were extensively explored, a …

A topological superconductor is characterized by having a pairing gap in the bulk and
gapless self-hermitian Majorana modes at its boundary. In one dimension, these are zero …

For the classification of topological phases of matter, an important consideration is whether a
system is spinless or spinful, as these two classes have distinct symmetry algebra that gives …

We establish the existence of a topological classification of many-particle quantum systems
undergoing unitary time evolution. The classification naturally inherits phenomenology …

Motivated by a recent experiment in which zero-bias peaks have been observed in scanning
tunneling microscopy (STM) experiments performed on chains of magnetic atoms on a …

We consider a model for a one-dimensional quantum wire with Rashba spin-orbit coupling
and repulsive interactions, proximity coupled to a conventional s-wave superconductor …

We present a detailed investigation of the topological phases and Majorana fermion (MF)
excitations that arise from the bulk interplay between (un) conventional one-and two-band …

Although nonsymmorphic symmetry protects Z 4 topology for Hermitian systems, non-
Hermitian topological phenomena induced by such a unique topological structure remain …

We construct microscopical models of one-dimensional noninteracting topological insulators
in all of the chiral universality classes. Specifically, we start with a deformation of the Su …
