Origin of degenerate bound states in the continuum in a grating waveguide: Parity symmetry breaking due to mode crossing
Cole Reynolds, Vladimir Kocharovsky, Vitaly Kocharovsky
We explain the origin of bound states in the continuum (BICs) in a planar grating waveguide, in particular, a mechanism for formation of degenerate BICs, via the analytical theory…
Quantum supremacy of the many-body fluctuations in the occupations of the excited particle states in a Bose-Einstein-condensed gas
Vitaly V. Kocharovsky, Vladimir V. Kocharovsky, Sergey V. Tarasov
We find a universal analytic formula for a characteristic function (Fourier transform) of a joint probability distribution for the particle occupation numbers in a BEC gas and the…
Bose-Einstein condensate fluctuations versus an interparticle interaction
Sergey V. Tarasov, Vladimir V. Kocharovsky, Vitaly V. Kocharovsky
We calculate the Bose-Einstein condensate (BEC) occupation statistics vs. the interparticle interaction in a dilute gas with a nonuniform condensate in a box trap within the Bogoli…
Self-similar analytical solution of the critical fluctuations problem for the Bose-Einstein condensation in an ideal gas
Vitaly V. Kocharovsky, Vladimir V. Kocharovsky
Paper is published in J. Phys. A: Math. Theor. 43 (2010) 225001, doi:10.1088/1751-8113/43/22/225001. Exact analytical solution for the universal probability distribution of the ord…
Analytical theory of mesoscopic Bose-Einstein condensation in ideal gas
Vitaly V. Kocharovsky, Vladimir V. Kocharovsky
We find universal structure and scaling of BEC statistics and thermodynamics for mesoscopic canonical-ensemble ideal gas in a trap for any parameters, including critical region. We…
Microscopic theory of a phase transition in a critical region: Bose-Einstein condensation in an interacting gas
Vitaly V. Kocharovsky, Vladimir V. Kocharovsky
We present a microscopic theory of the second order phase transition in an interacting Bose gas that allows one to describe formation of an ordered condensate phase from a disorder…
