    ABSTRACT: The present study deals with time-meridian surfaces and its Lorentz transformations in a new spacetime Heisenberg spacetime. We give a geometrical description of time-meridian surfaces around biharmonic particle in \({\mathsf {H}_{1}^{4}} .\) Finally, we obtain Lorentz transformations this particles.

    ABSTRACT: In the present paper, it is proposed the renormalization techniques in the investigation of phase transition phenomena in p-adic statistical mechanics. We mainly study p-adic λ-model on the Cayley tree of order two. We consider generalized p-adic quasi Gibbs measures depending for the λ-model. Such measures are constructed by means of certain recurrence equation, which defines a dynamical system. We study two regimes with respect to parameters. In the first regime we establish that the dynamical system has one attractive and two repelling fixed points, which predicts the existence of a phase transition. In the second regime the system has two attractive and one neutral fixed points, which predicts the existence of a quasi phase transition. A main point of this paper is to verify (i.e. rigorously prove) and confirm that the indicated predictions (via dynamical systems point of view) are indeed true. To establish the main result, we employ the methods of p-adic analysis, and therefore, our results are not valid in the real setting.

    ABSTRACT: We derive an approximation approach to the evolution of the fragmentation functions at Leading-Order (LO) by using a Laplace-transform technique. We calculate the fragmentation functions for meson states of \(c\bar {c}\) (η,ψ) in LO and evolution up to the high factorization scales. Our results for the fragmentation functions are in good agreement with other results.

    ABSTRACT: Using the method of QCD sum rules, we derive the correlator π Z for a state consisting of two charm quarks and two light quarks, \(c\bar {d}\bar {c}u\) , and carry out a Borel transform to find π Z (M B ). From this we find the solution that M B ≃ 3.9 ±. 2 GeV, showing that the Z c(3900) is a tetra-quark state.

    ABSTRACT: Local adiabatic search has been implemented on the quantum circuit model, and the time steps necessary to guarantee the approximation precision are of the same order as the time complexity of the algorithm. However, it is easy to verify that this conclusion doesn’t hold for global adiabatic search. But we know that adiabatic computing is equivalent to the circuit model of quantum computation. Therefore, there must exist a corresponding quantum circuit that correctly implements such a global adiabatic search. In this Letter, we show that this indeed could be true.

    ABSTRACT: The paper by Bokhari et al. [1] needs improvement. There are some incorrect/incomplete results and misleading conclusions that are addressed in this comment.Misleading Title:The title of the paper by Bokhari et al. Classification of spherically symmetric static spacetimes by Noether symmetries [1] is misleading. It gives the impression that a complete classification of spherically symmetric static space-times by their Noether symmetries is given in the paper. But in the abstract they themselves admit that “Noether symmetries of some of the well known spherically symmetric static solutions of the Einstein field equations are classified”. Indeed, they have not classified the spherically symmetric static spacetimes, but have presented only the Noether symmetries of the Schwarzschild metric, the Minkowaski metric, the de-Sitter metric, the Bertotti Robinson metric, and the Einstein metric.Incomplete Set of the Noether Symmetries:The sets of Noether symmetries given for the Bertotti-Robinso ...

    ABSTRACT: We consider a ring optomechanical cavity consisted of a fixed mirror and two movable mirrors which filled with two-level atomic media. We demonstrate the existence of the analog of multiple optomechanically induced transparency in the output field. The results show that the width of transparency windows increase with the increasing of atomic decay rate in selected parameter range, the larger decay rate of atoms the wider of the window of transparency. Our results also prove that the number of transparency windows associated with the frequencies of two oscillator modes.

    ABSTRACT: Our purpose in this paper is to present mathematical ways for entanglement transfers of arbitrary multipartite W state and W-type state under the local operation and classical communications. Two cases of general entanglement transfers and entanglement concentrations are completely addressed. With the symmetry special nonlinear equivalent optimizations may be used to obtain the optimal success probabilities. They are implementable in physics based on adaptable method based on sequenced local quantum measurements. Our new method is also extended to general bipartite entanglement transfers.

    ABSTRACT: We investigate the squeezing dynamics of the Kerr-down conversion system under a certain condition with Dicke squeezing parameter. By numerically calculating the squeezing parameter, we show that the squeezing is independent of the frequencies of the first and second mode; the stronger coupling induces stronger squeezing and longer time interval of squeezing.

    ABSTRACT: The quantum dynamics of a localized spin \(-\frac {1}{2} \) Particle interacting with an absorbing environment is investigated. The quantum Langevin-Schrödinger equation for spin \(-\frac {1}{2} \) is obtained. The susceptibility function of the environment is calculated in terms of the coupling function of the spin and the environment. it is shown that the susceptibility function satisfies the Kramers-Kronig relations. Spontaneous emission and the shift frequency of the spin is obtained in terms of the imaginary part of the susceptibility function in frequency domain. Some transition probabilities between the spin states are calculated when the absorbing environment is in the thermal state.

    ABSTRACT: This paper illustrates the resemblance between the information-geometric structures of probability spaces and that of the discrete spectrum for Hawking radiation. The information geometry gives rise to a reconstruction of the standard formalism of quantum mechanics, while the discrete spectrum of Hawking radiation contributes to the semiclassical unitary evolution of Hawking radiation. If more realistic models of Hawking radiation are chosen, the information-geometric structures of the probability space for Hawking radiation can be constructed from some physical considerations. The constructed quantum formalism is consistent with both the unitary evolution of Hawking radiation in the semiclassical picture and the topology change of fuzzy horizons. These aspects of Hawking radiation can be connected to some general convictions of quantum gravity such as holography. A comparison with the fuzzball proposal shows the limiation and effectiveness of this construction. We conclude that these information-geometric aspects show some possible ways bridging the gap between semiclassical models and quantum gravity.

    ABSTRACT: We propose a scheme to realize entanglement swapping, entangling two distant ions without a direct interaction in the trapped-ion systems. The two ions without interacting previously can be entangled with the success probability unity. This scheme does not need Bell-state measurement and is insensitive to the thermal motion.

    ABSTRACT: The Casimir effect for parallel plates satisfying the Dirichlet boundary condition in the context of effective QED coming from a six-dimensional Nielsen-Olesen vortex solution of the Abelian Higgs model with fermions coupled to gravity is studied at finite temperature. We find that the sign of the Casimir energy remains negative under the thermal influence. It is also shown that the Casimir force between plates will be weaker in the higher-temperature surroundings while keeps attractive. This Casimir effect involving the thermal influence is still inconsistent with the known experiments. We find that the thermal correction can not compensate or even reduce the modification from this kind of vortex model to make the Casimir force to be in less conflict with the measurements.
