Journal of Mathematical Physics Impact Factor & Information
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.

Article: New complex function space related to both entangled state representation and spin coherent state

ABSTRACT: In this paper, we study the relationship between operator space norm and operator space numerical radius on the matrix space $\mathcal{M}_n(X)$, when $X$ is a numerical radius operator space. Moreover, we establish several inequalities for operator space numerical radius and the maximal numerical radius norm of $2\times 2$ operator matrices and their offdiagonal parts. One of our main results states that if $(X, (O_n))$ is an operator space, then \begin{align*} \frac12\max\big(W_{\max}(x_1+x_2)&, W_{\max}(x_1x_2) \big)\\ &\le W_{\max}\Big(\begin{bmatrix} 0 & x_1 \\ x_2 & 0 \end{bmatrix}\Big)\\ &\hspace{1.5cm}\le \frac12\left(W_{\max}(x_1+x_2)+ W_{\max}(x_1x_2) \right) \end{align*} for all $x_1, x_2\in \mathcal{M}_n(X)$.Journal of Mathematical Physics 07/2015; 57(1).

ABSTRACT: We consider $S$matrix correlation functions for a chaotic cavity having $M$ open channels, in the absence of timereversal invariance. Relying on a semiclassical approximation, we compute the average over $E$ of the quantities ${\rm Tr}[S^\dag(E\epsilon)S(E+\epsilon)]^n$, for general positive integer $n$. Our result is an infinite series in $\epsilon$, whose coefficients are rational functions of $M$. From this we extract moments of the time delay matrix $Q=i\hbar S^\dag dS/dE$, and check that the first 8 of them agree with the random matrix theory prediction from our previous paper.Journal of Mathematical Physics 07/2015; 56(6).

ABSTRACT: We consider the statistics of time delay in a chaotic cavity having $M$ open channels, in the absence of timereversal invariance. In the random matrix theory approach, we compute the average value of polynomial functions of the time delay matrix $Q=i\hbar S^\dag dS/dE$, where $S$ is the scattering matrix. Our results do not assume $M$ to be large. In a companion paper, we develop a semiclassical approximation to $S$matrix correlation functions, from which the statistics of $Q$ can also be derived. Together, these papers contribute to establishing the conjectured equivalence between the random matrix and the semiclassical approaches.Journal of Mathematical Physics 07/2015; 56(6).

ABSTRACT: We describe the structure of all continuous algebraic endomorphisms of the open unit ball $\mathbf{B}$ of $\mathbb{R}^3$ equipped with the Einstein velocity addition. We show that any nonzero such transformation originates from an orthogonal linear transformation on $\mathbb{R}^3$.Journal of Mathematical Physics 06/2015; 56(8).

ABSTRACT: In the present paper, we present an integrable hierarchy for the ZakharovIto system. We first construct the Lenard recursion sequence and zero curvature representation for the ZakharovIto system, following Cao’s method as significantly generalized by other authors. We then construct the biHamiltonian structures employing variational trace identities but woven together with the Lenard recursion sequences. From this, we are in a position to construct an integrable hierarchy of equations from the ZakharovIto system, and we obtain the recursion operator and Poisson brackets for constructing this hierarchy. Finally, we demonstrate that the obtained hierarchy is indeed Liouville integrable.Journal of Mathematical Physics 06/2015; 56(6). DOI:10.1063/1.4922361  [Show abstract] [Hide abstract]
ABSTRACT: We consider a twodimensional (2D) jet by van der Waals gas streaming in parallel supersonic flow out of a duct into the atmosphere. We assume that the pressure p 0 of the oncoming uniform parallel flow is greater than the atmospheric pressure pA and belongs to ( p 1 e , p 2 i ) . Then at the corners at exit the oncoming flow expands in two symmetric jumpfan (jf) composite waves to the atmospheric pressure. These two jf composite waves interact and emerge as simple waves from their zone of penetration. We present a mathematical analysis of the interaction of the jf composite waves. To construct the flow in the interaction region, we consider a discontinuous Goursat problem for the 2D isentropic irrotational steady Euler equations. The existence of global piecewise C 1 solution to the discontinuous Goursat problem is obtained constructively.Journal of Mathematical Physics 06/2015; 56(6):061504.

ABSTRACT: In this paper, we prove that a real lattice symmetric reflection positive translationinvariant pure state of B = ⊗ j ∈ Z M d ( j ) ( C ) admits split property, if and only if its twopoint spatial correlation functions decay exponentially. We use amalgamated representation of Cuntz algebras to represent twopoint spatial correlation functions on an augmented Hilbert space. The underling symmetries and reflection positive property of the pure state make it possible to investigate its split and decaying twopoint correlation functions properties as spectral properties of a contractive selfadjoint operator on the augmented Hilbert space. Haag duality property of the pure state is crucially used in the analysis.Journal of Mathematical Physics 06/2015; 56(6):061701. DOI:10.1063/1.4922013  [Show abstract] [Hide abstract]
ABSTRACT: We develop a method to construct various classes of onedimensional periodic potentials with two intersecting energy bands. Analytical exact results for the zerogap states are presented in an explicit form under certain parameter conditions. The position of the energies of these zerogap states in the energy bands is identified numerically.Journal of Mathematical Physics 06/2015; 56(6):062101.
