Soliton diffusion in a Bose-Einstein condensate: A signature of the analogue Hawking radiation
Physics Letters B, 2019 The analog Hawking radiation (HR) emanating from a sonic black hole horizon formed in a cigar-shaped Bose-Einstein condensate (BEC) at finite temperature is investigated. In particular, we study the effect of HR on a dark (topological) soliton.

Electromagnetic quantum shifts in relativistic Bose-Einstein condensation
Physics Letters B, 2021 We compute deviations from ideal gas behavior of the pressure, density, and Bose-Einstein condensation temperature of a relativistic gas of charged scalar bosons caused by the current-current interaction induced by electromagnetic quantum fluctuations ...

Bose-Einstein Condensation of Erbium [PDF]
Physical Review Letters, 2012 We report on the achievement of Bose-Einstein condensation of erbium atoms and on the observation of magnetic Feshbach resonances at low magnetic field. By means of evaporative cooling in an optical dipole trap, we produce pure condensates of $^{168}$Er, containing up to $7 \times 10^{4}$ atoms.

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 ...

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.

Basics of Bose-Einstein condensation [PDF]
Physics of Particles and Nuclei, 2011 The review is devoted to the elucidation of the basic problems arising in the theoretical investigation of systems with Bose-Einstein condensate. Understanding these challenging problems is necessary for the correct description of Bose-condensed systems.
