Journal of Mathematical Physics, Volume 64, Issue 3, March 2023. Recently, a non-abelian generalization of the Navier–Stokes equation that exhibits a manifest duality between color and kinematics has been proposed by Cheung and Mangan. In this paper, w…
Journal of Mathematical Physics, Volume 64, Issue 3, March 2023. This paper provides a new geometric framework to describe non-conservative field theories with explicit dependence on the space–time coordinates by combining the k-cosymplectic and k-cont…
Journal of Mathematical Physics, Volume 64, Issue 3, March 2023. The diffraction spectrum of an aperiodic solid is related to the group of eigenvalues of the dynamical system associated with the solid. Those eigenvalues with continuous eigenfunctions c…
Journal of Mathematical Physics, Volume 64, Issue 3, March 2023. We use the tridiagonal representation approach to solve the radial Schrödinger equation for the continuum scattering states of the Coulomb problem in a complete basis set of discrete Bess…
Journal of Mathematical Physics, Volume 64, Issue 3, March 2023. This article contains essentially a rewriting of several properties of two well-known quantities, the so-called theta symbol (or triangular symbol), which is rational, and the 6j symbol, …
Journal of Mathematical Physics, Volume 64, Issue 3, March 2023. We make a number of simplifications in Gour and Friedland’s proof of local additivity of the minimum output entropy of a quantum channel. We follow them in reframing the question as one a…
Journal of Mathematical Physics, Volume 64, Issue 3, March 2023. The dynamics of some non-conservative and dissipative systems can be derived by calculating the first variation of an action-dependent action according to the variational principle of Her…
Journal of Mathematical Physics, Volume 64, Issue 3, March 2023. The qualitative difference in low-energy properties of spin S quantum antiferromagnetic chains with integer S and half-odd-integer S discovered by Haldane [F. D. M. Haldane, arXiv:1612.00…
Journal of Mathematical Physics, Volume 64, Issue 3, March 2023. We investigate non-homogeneous Hamiltonian operators composed of a first order Dubrovin–Novikov operator and an ultralocal one. The study of such operators turns out to be fundamental for…
Journal of Mathematical Physics, Volume 64, Issue 3, March 2023. This Review concerns recent results on the quantitative study of convergence toward the stationary state for spatially inhomogeneous kinetic equations. We focus on analytical results obta…
