An exactly solvable Kitaev model in a two-dimensional square lattice exhibits a topological
quantum phase transition which is different from the symmetry-breaking transition at zero …

Much has been learned regarding dynamical quantum phase transition (DQPT) due to
sudden quenches across quantum critical points in traditional quantum systems. However …

Frustration and quantum entanglement are two exotic quantum properties in quantum many-
body systems. However, despite several efforts, an exact relationship between them remains …

It is widely accepted that the dynamic of entanglement in presence of a generic circuit can
be predicted by the knowledge of the statistical properties of the entanglement spectrum. We …

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 study dynamical properties of the finite-size fully connected Ising model with a
transverse field at zero temperature. In a quench dynamics, we study the time period and the …

We investigate the dynamical quantum phase transition (DQPT) in the multi-band Bloch
Hamiltonian of the one-dimensional periodic Kitaev model, focusing on quenches from a …

We study the properties of multipartite quantum correlation (MQC) in a one-dimensional spin-
1/2 XY chain, where the three-spin reduced states are focused on and the four introduced …

We consider the ground-state phase diagram of a one-dimensional spin-1/2 XXZ chain with
a spatially modulated Dzyaloshinskii-Moriya interaction in the presence of an alternating …

Non-Hermitian rotation-time reversal (RT)-symmetric spin models possess two distinct
phases, the unbroken phase in which the entire spectrum is real and the broken phase …
