Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Two-dimensional Bose–Einstein condensate under pressure

open access: yesNew Journal of Physics, 2015
Evading the Mermin–Wagner–Hohenberg no-go theorem and revisiting with rigor the ideal Bose gas confined in a square box, we explore a discrete phase transition in two spatial dimensions.

Structure of condensed gas in the uniform medium

open access: yesCumhuriyet Science Journal, 2020
The Bose-Einstein condensate, which has very low particle density and a highly complex quantum structure, has been proven experimentally for rubidium, sodium, lithium, hydrogen, metastable helium, cesium and chromium atoms to date.

Generation of Anisotropic Second‐Harmonic Petal‐Like Beams with NbOBr2 Holograms

open access: yesAdvanced Photonics Research, Volume 7, Issue 4, April 2026.
Highly anisotropic second‐harmonic petal‐like beams with different combinations of the topological charges of vortex beams are produced using ultrathin NbOBr2 holograms. These demonstrations provide a pathway toward the development of chip‐scale polarization‐sensitive functional optical devices for many applications.

Bose–Einstein condensation of 162Dy and 160Dy

open access: yesNew Journal of Physics, 2015
We report Bose–Einstein condensation of two isotopes of the highly magnetic element dysprosium: ^162 Dy and $^{160}$ Dy. For ^162 Dy, condensates with 10 ^5 atoms form below T = 50 nK. We find the evaporation efficiency for the isotope ^160 Dy to be poor;

The Canonical Perfect Bose Gas in Casimir Boxes

open access: yes, 2004
We study the problem of Bose-Einstein condensation in the perfect Bose gas in the canonical ensemble, in anisotropically dilated rectangular parallelpipeds (Casimir boxes).

Merging van der Waals Materials and Optical Metasurfaces for Cavity Quantum Electrodynamics

open access: yesNanophotonics, Volume 15, Issue 5, 16 March 2026.
Flat optical metasurfaces supporting quasi‐bound states in the continuum (qBIC) enable cavity‐like, high‐Q resonances in ultrathin nanostructures. This perspective explores the emergence of cavity quantum electrodynamics in qBIC metasurfaces, specifically those made from ultrathin van der Waals nanostructures, where cavities and emitters are seamlessly

Transition of a mesoscopic bosonic gas into a Bose-Einstein condensate

open access: yes, 2011
The condensate number distribution during the transition of a dilute, weakly interacting gas of N=200 bosonic atoms into a Bose-Einstein condensate is modeled within number conserving master equation theory of Bose-Einstein condensation.

Bose-Einstein Condensation of Photons versus Lasing and Hanbury Brown-Twiss Measurements with a Condensate of Light

open access: yes, 2016
The advent of controlled experimental accessibility of Bose-Einstein condensates, as realized with e.g. cold atomic gases, exciton-polaritons, and more recently photons in a dye-filled optical microcavity, has paved the way for new studies and tests of a
