Two-dimensional Bose–Einstein condensate under pressure
New 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
Cumhuriyet 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
Advanced 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
New 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;

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

Emerging Device Applications From Strong Light–Matter Interactions in 2D Materials
Advanced Science, Volume 13, Issue 17, 23 March 2026.Two‐dimensional semiconductors enable extremely compact optoelectronic devices such as solar cells, sensors, LEDs, and lasers. Their strong light–matter interactions allow efficient light emission, detection, and energy conversion. This review article discusses the recent progress in integrating these materials with optical cavities and nanostructures ...

Coupling Enhancement and Symmetrization in Dissipative Optomechanical Systems
Annalen der Physik, Volume 538, Issue 3, March 2026.A practical circuit‐QED scheme with dual coherent laser driving and enhanced cross‐Kerr nonlinearity is presented to achieve ultrastrong optomechanical coupling in the few‐photon regime. A symmetric optomechanical dynamical framework is further established to enable a systematic classification of different coupling regimes.

Particle number fluctuations in a non-ideal pion gas
EPJ Web of Conferences, 2018 We consider a non-ideal hot pion gas with the dynamically fixed number of particles in the model with the λφ4 interaction. The effective Lagrangian for the description of such a system is obtained by dropping the terms responsible for the change of the ...
