The simple system of two two-level identical atoms couple to single-mode optical cavity in the resonance case is studied for investigating thermal entanglement. It interesting see that critical temperature only dependent on coefficient atom-atom dipole-dipole interaction. Based mode, we construct and investigate a entangled quantum Otto engine (QOE). Expressions several important performance parameters such as heat transferred, work done cycle, efficiency QOE zero $G$ are derived terms...
This paper deals mainly with the application of second-order symplectic implicit midpoint rule and its symmetric compositions to a post-Newtonian Hamiltonian formulation canonical spin variables in relativistic compact binaries. The rule, as basic algorithm, is directly used integrate completely system. On other hand, there are composite methods based on splitting into two parts: Newtonian part associated Kepler motion, perturbation involving orbital contributions, where flow has an analytic...
For a 10-dimensional post-Newtonian canonical conservative Hamiltonian system of spinning compact binaries, where the orbital part is accurate to third-order expansion and spin–orbit contributions are up next-to-next-to-leading order, its dynamics integrable not at all chaotic due presence five independent isolating integrals, including total energy, three components angular momentum vector length momentum. As spin–spin effects two bodies further included, only no longer conserved, so that...
We theoretically study the phase sensitivity of an SU(1,1) interferometer, in which shift is induced by a Kerr medium, together with coherent state input and homodyne detection. Considering both ideal photon-loss cases, results show that compared linear-phase-shift-based Kerr-phase-shift-based [KSU(1,1)] interferometer can significant enhancement quantum Fisher information even presence photon losses. In particular, without losses, KSU(1,1) break through standard limit Heisenberg (HL), close...
Abstract This study used molecular dynamics software LAMMPS to simulate the surface binding energy of W1-xMox (x=0,0.9375,0.875,0.75,0.625,0.5) alloy (110) surface. The effect thermal vibration, model size, step size and temperature for comprehensively considered. Finally, reference values W-Mo alloys with different concentrations were obtained, it was found that, within simulation range, as Mo concentration increased, W atoms increased from 11.661±0.017 eV 12.058±0.047 eV, while decreased...
Abstract In the NanChang Spherical Tokamak (NCST), for first time, experimental research was carried out on dual-step toroidal field coil power supply system, which is specifically designed to assist plasma current startup through electron cyclotron resonance heating (ECRH). The results demonstrate that, in comparison preceding system more effective aligning with ECRH and optimizing utilisation of {toroidal electric field}. This has resulted an increase from 30 kA 40 kA, extension discharge...
In general, there are differences between Lagrangian and Hamiltonian approaches at the same post-Newtonian (PN) order in a coordinate system under gauge. They from truncation of higher-order PN terms. do not affect qualitative quantitative results two for weak gravitational such as Solar System. Nevertheless, they may make have somewhat or completely different dynamical features integrability nonintegrability (or chaos) strong field. Even if features, when distances among compact objects...
A novel efficient semi-quantum private comparison protocol based on the d-dimensional GHZ states is proposed. With assistance of semi-honest third party, two classical participants can compare size relation their secretswithout any information leakage. To reduce consumption quantum devices, qubit efficiency our isimproved by introducing conception via existing privatecomparisons. Furthermore,it unnecessary to prepare secure authentication channel among in advance. It shown that not only...
The Bohm criterion in a dusty plasma containing nonextensively distributed electrons and cold ions is investigated within the framework of probe model including effects dust charge fluctuation. It shown that critical Mach number upshifts with decrease electron nonextensive parameter (qe) increase ion-to-electron density ratio (Rn) when fluctuation are out consideration. Once included, Rn, increases first, then decreases. slop curves region Rn≫1 for qe>1 becomes more gradual than...
The structural stability, electronic structures, mechanical properties and Debye temperature of W-TM (TM = Cr, Cu, Fe, Mn, Mo Ni, respectively) alloys have been investigated by first principles method. lattice constant, cell volume, formation energy cohesive are calculated. still maintain bcc lattice, no phase transformation.

We study the phase sensitivity of an SU(1,1) interferometer with photon loss by using three different operations schemes, i.e., performing photon-addition operation on input port (Scheme A), interior B), and both them C). compare performance schemes in estimation same times to mode b. The results show that Scheme B improves best ideal case, C performs well against internal loss, especially case strong loss. All can beat standard quantum limit presence but break through a larger range.
