Environment-assisted squeezing in a coherently driven non-Hermitian degenerate parametric oscillator
Muhdin Abdo Wodedo, Berihu Teklu, Konstantin G. Zloshchastiev +2
Environment-assisted approaches to nonclassical light offer a practical path to strong squeezing in imperfect, lossy platforms. In this paper, we study a degenerate parametric osci…
Galaxy rotation curves in superfluid vacuum theory
Konstantin G. Zloshchastiev
Logarithmic superfluid theory of physical vacuum suggests that gravity has a multiple-scale structure; where one can recognize sub-Newtonian, Newtonian, logarithmic, linear and qua…
Sound propagation in cigar-shaped Bose liquids in the Thomas-Fermi approximation: A comparative study between Gross-Pitaevskii and logarithmic models
Konstantin G. Zloshchastiev
A comparative study is done of the propagation of sound pulses in elongated Bose liquids and Bose-Einstein condensates in Gross-Pitaevskii and logarithmic models, by means of the T…
Logarithmic wave-mechanical effects in polycrystalline metals: Theory and experiment
Maksym Kraiev, Kateryna Domina, Violeta Kraieva +1
Schrodinger-type wave equations with logarithmic nonlinearity occur in hydrodynamic models of Korteweg-type materials with capillarity and surface tension, which can undergo liquid…
Resolving the puzzle of sound propagation in a dilute Bose-Einstein condensate
Konstantin G. Zloshchastiev
A unified model of a dilute Bose-Einstein condensate is proposed, combining of the logarithmic and Gross-Pitaevskii nonlinear terms in a wave equation, where the Gross-Pitaevskii t…
Acoustic oscillations in cigar-shaped logarithmic Bose-Einstein condensate in the Thomas-Fermi approximation
Konstantin G. Zloshchastiev
We consider the dynamical properties of density fluctuations in the cigar-shaped Bose-Einstein condensate described by the logarithmic wave equation with a constant nonlinear coupl…
