We derive exact results for the Lindblad equation for a quantum spin chain (one-
dimensional quantum compass model) with dephasing noise. The system possesses doubly …

Non-Hermitian Hamiltonians provide a simple picture for inspecting dissipative systems with
natural or induced gain and loss. We investigate the Floquet dynamical phase transition in …

Out-of-time-order correlators (OTOCs) progressively play an important role in different fields
of physics, particularly in the nonequilibrium quantum many-body systems. In this paper, we …

Floquet dynamical quantum phase transitions (FDQPTs) are signified by recurrent
nonanalytic behaviors of observables in time. In this work, we introduce a quench-free and …

We calculate the dynamical spin structure factor of the generalized spin-1/2 compass spin
chain using the density matrix renormalization group. The model, also known as the twisted …

We study Nielsen complexity and Fubini-Study complexity for the transverse XY spin chain
and establish their nonanalyticity at the critical lines. We obtain the scaling behavior of both …

We revisit the problem of decoherence of a qubit centrally coupled to an interacting spin
environment, here modeled by a quantum compass chain or an extended XY model in a …

We study the ground state fidelity, fidelity susceptibility, and quench dynamics of the
extended quantum compass model in a transverse field. This model reveals a rich phase …

The matrix product state (MPS) is utilized to study the ground-state properties and quantum

The presence of a quantum critical point can significantly affect the thermodynamic
properties of a material at finite temperatures. This is reflected, eg, in the entropy landscape …
