A broadband outburst of the compact steep-spectrum quasar 3C 138 in 2024-2026
T. V. Mufakharov, Yu. V. Sotnikova, V. V. Vlasyuk +20
After several decades of relative quiescence, the compact steep-spectrum quasar 3C 138 entered an active phase in 2024-2026, exhibiting strong broadband flaring. We investigate its…
MellinBarnes Transformation for Two-Loop Master-Diagram
S. E. Derkachev, A. V. Ivanov, L. A. Shumilov
In the paper, we obtain an expression for a two-loop master-diagram by using the MellinBarnes transformation. In the two-dimensional case we managed to factorize the answer and…
Photoluminescence imaging of single photon emitters within nanoscale strain profiles in monolayer WSe
Artem N. Abramov, Igor Y. Chestnov, Ekaterina S. Alimova +6
Local deformation of atomically thin van der Waals materials provides a powerful approach to create site-controlled chip-compatible single-photon emitters (SPEs). However, the micr…
A quantum model of charge capture and release onto/from deep traps
Ivan I. Vrubel, Vasilii Khanin, Markus Suta +2
The rapid development of optical technologies and applications revealed the critical role of point defects affecting device performance. One of the powerful tools to study influenc…
Effects of bond disorder and surface amorphization on optical phonon lifetimes and Raman peak shape in crystalline nanoparticles
Oleg I. Utesov, Sergei V. Koniakhin, Andrey G. Yashenkin
Optical phonons in nanoparticles with the randomness of interatomic bonds are considered both analytically and numerically. For weak dilute disorder two qualitatively different reg…
Single collective excitation of an atomic array trapped along a waveguide: a study of cooperative emission for different atomic chain configurations
V. A. Pivovarov, L. V. Gerasimov, J. Berroir +4
Ordered atomic arrays trapped in the vicinity of nanoscale waveguides offer original light-matter interfaces, with applications to quantum information and quantum non-linear optics…
