Journal of Mathematical Physics, Volume 63, Issue 12, December 2022. We study the limiting behaviors of a generalized elephant random walk on the integer lattice. This random walk is defined by using two sequences of parameters expressing the memory at…
Journal of Mathematical Physics, Volume 63, Issue 12, December 2022. Quantum nonlocality is associated with the local indistinguishability of orthogonal states. Unextendible product basis (UPB), a widely used tool in quantum information, exhibits nonlo…
Journal of Mathematical Physics, Volume 63, Issue 12, December 2022. In this paper, using the Moser functions and linking theorem, we study the existence of solutions for a class of Hamiltonian Choquard-type elliptic systems in the plane with exponenti…
Journal of Mathematical Physics, Volume 63, Issue 12, December 2022. The aim of this paper is to study the periodic traveling wave solutions in a nonautonomous reaction-diffusion susceptible-infected-removed epidemic model with general nonlinear incide…
Journal of Mathematical Physics, Volume 63, Issue 12, December 2022. Using a generalized framework that consists of evolution of the solution to the Camassa–Holm equation and its energy measure, we establish the global-in-time orbital stability of peak…
Journal of Mathematical Physics, Volume 63, Issue 12, December 2022. This paper is devoted to studying a two-component peakon system with cubic nonlinearity, which is a two-component extension of the cubic Camassa–Holm equation. We first discuss the lo…
Journal of Mathematical Physics, Volume 63, Issue 12, December 2022. We investigate Dirac’s bra–ket formalism based on a rigged Hilbert space for a non-Hermitian quantum system with a positive-definite metric. First, the rigged Hilbert space, character…
Journal of Mathematical Physics, Volume 63, Issue 12, December 2022. The damping term has an important effect on the existence of solution in fluid dynamics. In this paper, we will consider the threshold phenomenon of global existence and blow up of so…
Journal of Mathematical Physics, Volume 63, Issue 12, December 2022. Two modified Boussinesq equations along with their Lax pairs are proposed by introducing the Miura transformations. The modified good Boussinesq equation with initial condition is inv…
Journal of Mathematical Physics, Volume 63, Issue 12, December 2022. We start with the 13 central configurations of the restricted (4 + 1) body problem having four primaries with equal masses at the vertices of a square. Then, we describe the evolution…
