One of the unique features of non-Hermitian Hamiltonians is the non-Hermitian skin effect,
namely, that the eigenstates are exponentially localized at the boundary of the system. For …

The topology of non-Hermitian systems is drastically shaped by the non-Hermitian skin
effect, which leads to the generalized bulk-boundary correspondence and non-Bloch band …

Absence of quasiparticle-level anticrossing in random non-Hermitian systems is
demonstrated. As a result, the general Wigner-Dyson distributions of energy-level spacing of …

We study the emergence of non-Hermitian band topology in a two-dimensional metal with
planar spiral magnetism due to a momentum-dependent relaxation rate. A sufficiently strong …

We investigate the Hall conductance of a two-dimensional Chern insulator coupled to an
environment causing gain and loss. Introducing a biorthogonal linear response theory, we …

We study a non-Hermitian and nonunitary version of the two-dimensional Chalker-
Coddington network model with balanced gain and loss. This model belongs to the class D† …
