Transport in non-Hermitian quantum systems is studied. The goal is a better understanding
of transport in non-Hermitian systems like the Lieb lattice due to its flat bands and the …

Non-Hermitian skin effect (NHSE) is a unique feature studied extensively in noninteracting
non-Hermitian systems. In this paper, we extend the NHSE originally discovered in …

The non-Hermitian skin effect, in which eigenstates of non-Hermitian Hamiltonians are
localized at one boundary in the open boundary condition, has attracted great interest …

Many-body interactions give rise to the appearance of exotic phases in Hermitian physics.
Despite their importance, many-body effects remain an open problem in non-Hermitian …

Spin transport theory of non-Hermitian quantum systems, where the non-Hermiticity led to a
series of exotic phenomena when the system experiences dissipation to an environment is …

We study the late-time dynamics of two particles confined in one spatial dimension and
subject to two-body losses. The dynamics is exactly described by a non-Hermitian …

Identifying phase boundaries of interacting systems is one of the key steps to understanding
quantum many-body models. The development of various numerical and analytical methods …

Dramatically different from the Hermitian systems, the conventional bulk-boundary
correspondence (BBC) is broken in the non-Hermitian systems. In this paper, we use edge …

The emergence of chiral anomaly entails various fascinating phenomena such as
anomalous quantum Hall effect and chiral magnetic effect in different branches of (non-) …

We study non-Hermitian (NH) fermionic superfluidity subject to dissipation of Cooper pairs
on a honeycomb lattice, for which we analyze the attractive Hubbard model with a complex …
