Single-impurity-induced Dicke quantum phase transition in a cavity-Bose-Einstein condensate

Scientific Reports, 2017
We present a new generalized Dicke model, an impurity-doped Dicke model (IDDM), by the use of an impurity-doped cavity-Bose-Einstein condensate (BEC).

Chaotic motion of scalar particle coupling to Chern–Simons invariant in Kerr black hole spacetime

European Physical Journal C: Particles and Fields, 2021
We present firstly the equation of motion for the test scalar particle coupling to the Chern–Simons invariant in Kerr black hole spacetime by the short-wave approximation. We have analyzed the dynamical behaviors of the test coupled particles by applying

Controlled quantum secret sharing [PDF]

Physica Scripta, 2006
We present a new protocol in which a secret multiqubit quantum state $\ket $ is shared by $n$ players and $m$ controllers, where $\ket $ is the encoding state of a quantum secret sharing scheme. The players may be considered as field agents responsible for carrying out a task, using the secret information encrypted in $\ket $, while the controllers ...

Pole placement design for quantum systems via coherent observers

, 2015
We previously extended Luenberger's approach for observer design to the quantum case, and developed a class of coherent observers which tracks linear quantum stochastic systems in the sense of mean values.

Generalized superconductors from the coupling of a scalar field to the Einstein tensor and their refractive index in massive gravity

European Physical Journal C: Particles and Fields, 2019
We construct the generalized superconductors from the coupling of a scalar field to the Einstein tensor in the massive gravity and investigate their negative refraction in the probe limit.
