Vortex State of Ultralight Dark Matter and the Fornax Timing Problem
V. Gorkavenko, O. Barabash, T. Gorkavenko +4
We investigate the impact of the vortex state of the ultralight dark matter (ULDM) on the dynamical friction acting on moving globular clusters. Comparing this force with that for…
Effects of Curvature-Scalar Coupling on Vacuum Energy in Flat (3+1)-Dimensional Space-Time
Volodymyr Gorkavenko, Oleh Barabash, Pavlo Nakaznyi +3
We investigated how a magnetic topological defect affects the vacuum polarization of a charged massive scalar field in a flat -dimensional space-time. The defect was modeled…
Near-Threshold OPE Constraints and High-Energy Diffractive Dynamics in J/psi Photoproduction
Arkadiy I. Syamtomov
The paper studies exclusive J/ψ photoproduction near the production threshold using leading‑twist Coulombic OPE with target‑mass resummation and fits to recent GlueX and CLAS12 dat…
Effective scalaron--photon interaction in gravity
Yuri Shtanov
We revisit the effective coupling of the scalaron to gauge fields in gravity minimally coupled to the Standard Model, focusing on the scalaron decay into two photons. Treati…
Nonclassical photocounting statistics with a single on-off detector
V. S. Kovtoniuk, M. Bohmann, A. A. Semenov
Any single on-off photocounter, which can only detect the presence or absence of photons without discriminating their number, is not capable of identifying nonclassical nature of l…
Integrable Twelve-Component Nonlinear Dynamical System on a Quasi-One-Dimensional Lattice
Oleksiy O. Vakhnenko, Vyacheslav O. Vakhnenko
Bearing in mind the potential physical applicability of multicomponent completely integrable nonlinear dynamical models on quasi-one-dimensional lattices we have developed the nove…
