Journal of Mathematical Physics (J MATH PHYS)
Journal description
Journal of Mathematical Physics is published monthly by the American Institute of Physics. Its purpose is the publication of papers in mathematical physics ñ that is, the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories. The mathematics should be written in a manner that is understandable to theoretical physicists. Occasionally, reviews of mathematical subjects relevant to physics and special issues combining papers on a topic of current interest may be published.

ABSTRACT: We first study a class of fundamental quantum stochastic processes induced by the generators of a six dimensional nonsolvable Lie †algebra consisting of all linear combinations of the generalized Gross Laplacian and its adjoint, annihilation operator, creation operator, conservation, and time, and then we study the quantum stochastic integrals associated with the class of fundamental quantum stochastic processes, and the quantum Itô formula is revisited. The existence and uniqueness of solution of a quantum stochastic differential equation is proved. The unitarity conditions of solutions of quantum stochastic differential equations associated with the fundamental processes are examined. The quantum stochastic calculus extends the HudsonParthasarathy quantum stochastic calculus.  [Show abstract] [Hide abstract]
ABSTRACT: In this paper, we discuss the formation of brine channels in sea ice. The model includes a timedependent GinzburgLandau equation for the solidliquid phase change, a diffusion equation of the CahnHilliard kind for the solute dynamics, and the heat equation for the temperature change. The macroscopic motion of the fluid is also considered, so the resulting differential system couples with the NavierStokes equation. The compatibility of this system with the thermodynamic laws and a maximum theorem is proved. 
Article: Green’s functions and energy eigenvalues for deltaperturbed spacefractional quantum systems
[Show abstract] [Hide abstract]
ABSTRACT: Starting from the propagator, we introduced a timeordered perturbation expansion and employed Wick rotation to obtain a general energydependent Green’s function expressions for spacefractional quantum systems with Dirac deltafunction perturbation. We then obtained the Green’s functions and equations for the bound state energies for the spacefractional Schrödinger equation with single and double Dirac delta well potentials and the deltaperturbed infinite well.

ABSTRACT: We establish the global existence of smooth solutions to the Cauchy problem for a system of variational wave equations in one space dimension modeling a type of nematic liquid crystals that has equal splay and bend coefficients.

ABSTRACT: Quantum Bernoullinoises (QBNs) are the family of annihilation and creation operators acting on Bernoulli functionals, which can describe a twolevel quantum system with infinitely many sites. In this paper, we consider the problem to construct quantum Markov semigroups (QMSs) directly from QBNs. We first establish several new theorems concerning QBNs. In particular, we define the number operator acting on Bernoulli functionals by using the canonical orthonormal basis, prove its selfadjoint property, and describe precisely its connections with QBN in a mathematically rigorous way. We then show the possibility to construct QMS directly from QBN. This is done by combining the general results on QMS with our new results on QBN obtained here. Finally, we examine some properties of QMS constructed from QBN.

ABSTRACT: We study twoloop renormalization group flow (RG2) on Lorentzian threemanifolds. The fixed points of flow are analysed on a threedimensional Lorentzian manifold and we present a classification of the solitons that evolves only by homotheties. Furthermore, we prove the existence of a Lorentzian RG2 cigar soliton of constant positive curvature.  [Show abstract] [Hide abstract]
ABSTRACT: An extended version of the BogomolnyPrasadSommerfeld (BPS) Skyrme model that admits timedependent solutions is discussed. Initially, by introducing a power law at the original potential term of the BPS Skyrme model, the existence, stability, and structure of the corresponding solutions are investigated. Then, the frequency and halflifes of the radial oscillations of the constructed timedependent solutions are determined.  [Show abstract] [Hide abstract]
ABSTRACT: It was conjectured that the structural physical approximation (SPA) of an optimal entanglement witness is separable (or equivalently, that the SPA of an optimal positive map is entanglement breaking). This conjecture was disproved, first for indecomposable maps and more recently for decomposable maps. The arguments in both cases are sketched along with important related results. This review includes background material on topics including entanglement witnesses, optimality, duality of cones, decomposability, and the statement and motivation for the SPA conjecture so that it should be accessible for a broad audience.

ABSTRACT: Measurements on quantum channels are described by socalled process positive operator valued measures, or process POVMs. We study implementing schemes of extremal process POVMs. As it turns out, the corresponding measurement must satisfy certain extremality property, which is stronger than the usual extremality given by the convex structure. This property motivates the introduction and investigation of the Aconvex structure of POVMs, which generalizes both the usual convex and C*convex structures. We show that extremal points and faces of the set of process POVMs are closely related to Aextremal points and Afaces of POVMs, for a certain subalgebra A. We also give a characterization of Aextremal and Apure POVMs.
