The effect of population imbalance in p-wave superfluids in the BCS-BEC crossover regime at finite temperatures is studied through the path integral formalism. Using the Hubbard–Stratonovich transformation, the partition function of the system is c

The paper investigates the transition dynamic of a two-level system coupled uniformly to a general XY dissipative spin-chain environment with the Dzyaloshinsky-Moriya interaction. The collective effect of the spin-chain environment is studied and we

The paper investigates the effects of a two-level quantum system coupled to transversal and longitudinal dissipative environment. The time-dependent phase accumulation, LZ transition probability and entropy in the presence of fast-ohmic, sub-ohmic an

We consider a non-Hermitian Hamiltonian in order to effectively describe a dissipative spin chain in a transverse magnetic field. The model Hamiltonian is technically transformed to mimic the famous well known Landau–Zener two-level model. The time

The feasibility of stochastic Hamiltonians for interacting qubits to deliver consistent quantum speedups in quantum adiabatic optimisation remains an open question. This paper studies theoretically the noisy Landau–Zener model of a system of two in

We investigate the effect of plasmon screening on the polaron characteristics following the Feynman variational method and find that the screening considerably reduces the polaron characteristics, as plasmon density increases. We establish that the f

We examine the magnetopolaron state in a cylindrical quantum dot with a transverse parabolic potential and a high rectangular potential well in the longitudinal direction. The quadratic dependence of the magnetopolaron energy versus Fröhlich electro
