Quantum phase transitions are usually studied in terms of Hermitian Hamiltonians. However,
cold-atom experiments are intrinsically non-Hermitian because of spontaneous decay. Here …

We propose to realize the pseudo-Hermiticity in a cavity magnonics system consisting of the
Kittel modes in two small yttrium iron garnet spheres coupled to a microwave cavity mode …

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 …

We show that non-Hermitian dynamics generate substantial entanglement in many-body
systems. We consider the non-Hermitian Lipkin-Meshkov-Glick model and show that its …

We study a cluster Ising model with non-Hermitian external field which can be exactly solved
in the language of free fermions. By investigating the second derivative of energy density …

The non-Hermitian model exhibits counter-intuitive phenomena which are not observed in
the Hermitian counterparts. To probe the competition between non-Hermitian and Hermitian …

We show that weak measurement leads to unconventional quantum Zeno dynamics with
Raman-like transitions via virtual states outside the Zeno subspace. We extend this concept …

We report a global effect induced by the local complex field associated with the spin-
exchange interaction. High-order exceptional point up to (N+ 1)-level coalescence is created …

Non-Hermitian spin systems have attracted extensive interest due to their unconventional
magnetic properties, rich entanglement resources, and unusual quantum criticality …

A conventional quantum phase transition (QPT) can be accessed by varying a real
parameter at absolute zero temperature. Motivated by the discovery of the pseudo …
