Preserving Quantum Coherence in Thermal Noisy Systems Via Qubit Frequency Modulation
Advanced Quantum Technologies, Volume 9, Issue 6, June 2026.Frequency modulation is shown to preserve quantum coherence in a thermal phase‐covariant environment only under specific noise conditions. It protects a qubit against thermal dissipation from a Lorentzian reservoir, but fails against thermal pure dephasing from an Ohmic reservoir.

Numerical studies of vortices and dark solitons in atomic Bose-Einstein condensates [PDF]
, 2004 Dilute atomic Bose-Einstein condensates support intriguing macroscopic excitations in the form of quantized vortices and dark solitons. In this thesis we present extensive quantitative studies of the dynamics of these phenomena in the limit of zero ...

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.

The Modified Camassa–Holm Equation on the Half Line: A Riemann–Hilbert Approach
Studies in Applied Mathematics, Volume 156, Issue 6, June 2026.ABSTRACT We consider the initial‐boundary value (IBV) problem for the modified Camassa–Holm (mCH) equation m∼t+(u∼2−u∼x2+2u∼)m∼x=0,m∼:=u∼−u∼xx+1$\tilde{m}_t+{\left((\tilde{u}^2-\tilde{u}_x^2+2\tilde{u})\tilde{m}\right)}_x = 0, \qquad \tilde{m}:=\tilde{u}-\tilde{u}_{xx}+1$ on the half‐line x≥0$x \ge 0$.

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.

Standing waves of nonlinear Schrödinger systems with all attractive forces
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract Since the pioneering work of Lin and Wei on nonlinear Schrödinger systems of n$n$ components with interaction forces aij$a_{ij}$ between the i$i$‐th and j$j$‐th components for 1⩽i,j⩽n$1\leqslant i,j\leqslant n$, there have been numerous further developments in many directions. However, even in the simplest case where all interaction forces are

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;

Strong Plasmon–Exciton Coupling Tuned by Corner Etching of Gold Nanocubes and Nanotriangles
Advanced Optical Materials, Volume 14, Issue 18, 15 May 2026.Systematic etching of gold nanocubes (AuNCs) and nanotriangles (AuNTs) reveals how nanoparticle morphology governs plasmon–exciton strong coupling. While rounding the corners of AuNCs weakens their coupling, triangular geometries robustly preserve deep strong coupling.
