Asymmetric coupling amplitudes effectively create an imaginary gauge field, which induces
a non-Hermitian Aharonov-Bohm (AB) effect. Nonzero imaginary magnetic flux invalidates …

We systematically study a Kitaev chain with imbalanced pair creation and annihilation,
which is introduced by non-Hermitian pairing terms. An exact phase diagram shows that the …

Quantum degeneracy pressure (QDP) underscores the stability of matter and is arguably the
most ubiquitous many-body effect. The associated Fermi surface (FS) has broad implications …

The eigennmodes in a non-Hermitian system containing nonreciprocal couplings may
exhibit an extreme localization, also known as non-Hermitian skin effect (NHSE), under …

Degeneracy points and exceptional points embedded in the energy band are distinct
because of their topological features. We report a hybrid exceptional point formed through …

Symmetry plays fundamental role in physics and the nature of symmetry changes in non-
Hermitian physics. Here the symmetry-protected scattering in non-Hermitian linear systems …

Topological stability is an important property for topological materials. However, the non-
Hermitian effects may change this situation. Here, we investigate the robustness of edge …

We uncover a non-Hermitian skin mode in which the eigenmodes of a nonreciprocal
topoelectrical (TE) heterojunction circuit array are localized at the heterojunction interface …

We study a non-Hermitian Rice-Mele model without breaking time-reversal symmetry, with
the non-Hermiticity arising from imbalanced hopping rates. The Berry connection, Berry …

Parity-time symmetry is of great interest. The reciprocal and unidirectional features are
intriguing besides the symmetry phase transition. Recently, the reciprocal transmission …
