Fortschritte der Physik, Volume 74, Issue 1, January 2026.Abstract The propagation of a massive scalar field and a massless Dirac field in the geometry of a dilaton–de Sitter black hole is investigated. Starting from the covariant perturbation equations, the corresponding effective potentials are presented and their dependence on the dilaton charge, field mass, and cosmological constant is analyzed. Using the

ON THE LARGE ORDER ASYMPTOTICS OF THE WAVE FUNCTION PERTURBATION THEORY [PDF]
, 1995 The problem of finding the large order asymptotics for the eigenfunction perturbation theory in quantum mechanics is studied. The relation between the wave function argument x and the number of perturbation theory order k that allows us to construct the ...

Semiclassical Asymptotics Beyond All Orders for Simple Scattering Systems [PDF]
SIAM Journal on Mathematical Analysis, 1995 The scattering matrix \(S\) for the equation \(i\varepsilon {d\varphi(t)\over dt}= A(t)\varphi(t)\), when \(\varepsilon\to 0\), is considered. It is supposed that \(A\) is an analytic \(n\times n\) matrix whose eigenvalues are real and distinct for all \(t\). The asymptotics for the matrix \(S\) are given up to errors \(O(\exp(- k\varepsilon^{- 1}))\),

Nanophotonics, Volume 14, Issue 24, Page 4285-4299, December 2025.Abstract Both the polarization state of coherent bichromatic fields produced by harmonic generation and a class of anisotropic paraxial optical cavities are examples of commensurate two‐dimensional harmonic oscillators. The geometric phase for these systems is studied here, both in the classical/ray and quantum/wave regimes. The quantum geometric phase

Recursive Relations for the S‐matrix of Liouville Theory
Fortschritte der Physik, Volume 73, Issue 11, November 2025.Abstract The relation between the vertex operators of the in and out fields in Liouville theory is analyzed. This is used to derive equations for the S‐matrix, from which a recursive relation for the normal symbol of the S‐matrix for discrete center‐of‐mass momenta is obtained.

A Semiclassical Approach to the Nonlocal Nonlinear Schrödinger Equation with a Non-Hermitian Term
MathematicsThe nonlinear Schrödinger equation (NLSE) with a non-Hermitian term is the model for various phenomena in nonlinear open quantum systems. We deal with the Cauchy problem for the nonlocal generalization of multidimensional NLSE with a non-Hermitian term ...
