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

Unveiling Hidden Features of Strongly Correlated Quantum Systems Through a Complex‐Network Analysis
Advanced Quantum Technologies, EarlyView.By applying complex network theory, we report a fundamental and previously unobserved phenomenon in the finite‐size Kitaev model: a singular point at which uniform, nonzero entanglement emerges among all fermion pairs, forming a complete entanglement network.

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.

Is There A Pure Electronic Ferroelectric?
Advanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.The search for faster, more reliable ferroelectric materials has shifted from traditional lattice‐driven ferroelectrics, which rely on slow ionic displacements, to electronic ferroelectrics, where polarization is governed by electronic ordering. This shift enables ultrafast switching, low‐field operation, and resistance to fatigue.

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;

, 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

Skyrmionic Polarization Textures in Structured Dielectric Planar Media
Nanophotonics, Volume 15, Issue 3, 12 February 2026.Topological skyrmionic textures are typically associated with the structure of optical fields. This work demonstrates that they can also emerge from the optical response of structured metasurfaces. Through engineered light–matter interaction, polarization eigenstates acquire nontrivial topology, which can be mapped into the Chern‐insulator physics ...

Generalized Bose-Einstein condensation into multiple states in driven-dissipative systems
, 2013 Bose-Einstein condensation, the macroscopic occupation of a single quantum state, appears in equilibrium quantum statistical mechanics and persists also in the hydrodynamic regime close to equilibrium. Here we show that even when a degenerate Bose gas is

Entering the Strong Coupling Regime in Conventional Organic Solar Cells
Advanced Functional Materials, Volume 36, Issue 8, 26 January 2026.Organic solar cells convert light into fossil‐free energy, yet they still cannot compete with their silicon counterparts. Strong exciton‐photon coupling can ameliorate some properties of organic solar cells, but it requires additional mirrors that diminish light absorbance. Here, mirror‐free strong exciton‐photon coupling is implemented in conventional
