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

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.

ChemPhysChem, Volume 26, Issue 17, September 10, 2025.Selectivity and propensity have been emphasized for NO molecules scattered from a graphite surface, employing molecular dynamics simulation alongside a new potential energy surface, including an appropriate treatment of the long‐range interaction, governing the formation of the precursor state, that then reacts with the surface.

Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures
Contributions to Plasma Physics, Volume 65, Issue 7, August 2025.ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

Non-planar corrections in ABJM theory from quantum M2 branes
Journal of High Energy PhysicsThe quantization of semiclassical strings in AdS spacetimes yields predictions for the strong-coupling behaviour of the scaling dimensions of the corresponding operators in the planar limit of the dual gauge theory.

Electrical Conductivities and Low Frequency Opacities in the Warm Dense Matter Regime
Contributions to Plasma Physics, Volume 65, Issue 6, July 2025.ABSTRACT In this article, we examine different approaches for calculating low frequency opacities in the warm dense matter regime. The relevance of the average‐atom approximation and of different models for calculating opacities, such as the Ziman or Ziman–Evans models is discussed and the results compared to ab initio simulations.

On non-planar ABJM anomalous dimensions from M2 branes in AdS4 × S 7/ℤ k
Journal of High Energy PhysicsPlanar parts of conformal dimensions of primary operators in U k (N) × U −k (N) ABJM theory are controlled by integrability. Strong coupling asymptotics of planar dimensions of operators with large spins can be found from the energy of semiclassical ...

Symmetry, Integrability and Geometry: Methods and Applications, 2005 The complex WKB-Maslov method is used to consider an approach to the semiclassical integrability of the multidimensional Gross-Pitaevskii equation with an external field and nonlocal nonlinearity previously developed by the authors.
