In this paper, we use the concepts of quantum entanglement and coherence to analyze the
Unruh and anti-Unruh effects based on the model of Unruh–DeWitt detector. For the first …

Entanglement has developed into an essential concept for the characterization of phases
and phase transitions in ground states of quantum many-body systems. In this work we use …

We study and compare the time evolutions of concurrence and quantum discord in a driven
system of two interacting qubits prepared in a generic Werner state. The corresponding …

We compute different quantifiers to analyze the spontaneous generation of entanglement for
a unidirectional (nonreciprocal) two-two level system. We illustrate this approach by deriving …

Abstract Vector solitons in Bose–Einstein condensates are usually investigated analytically
with identical intra-and interatomic interactions (for an integrable model). We obtain six …

A quantum hydrodynamic model is developed for axial symmetric anisotropic short-range
interactions. The quantum stress tensor represents the interaction and is derived up to the …

We have examined the possibility of quantum dense coding for the V-shaped channel and
cylindrical geometry of plasmonic waveguides by assuming certain initial states at different …

We show that entanglement between two solitary qubits in quasi-one-dimensional Bose-
Einstein condensates can be spontaneously generated due to quantum fluctuations …

We explore the effect of using two-dimensional matter-wave vortices to confine an ensemble
of bosonic quantum impurities. This is modeled theoretically using a mass-imbalanced …

We investigate the quantum correlation dynamics in dark-soliton qubits with a special
attention to quantum discord. Recently, dark-soliton qubit exhibiting appreciably long lifetime …
