Modern theories of melting of two-dimensional systems are discussed that are mainly based
on the concepts of the Berezinskii–Kosterlitz–Thouless (BKT) theory of phase transitions in …

We study the statistical mechanics and the dynamical relaxation process of modulationally
unstable one-dimensional quantum droplets described by a modified Gross–Pitaevskii …

Recently, a method has been proposed to detect the rotation of a ring Bose-Einstein
condensate, in situ, in real-time, and with minimal destruction by using a cavity driven with …

We present numerical simulations of the cavity optomechanical detection of persistent
currents and bright solitons in an atomic Bose-Einstein condensate confined in a ring trap …

We study the vortex pinning effect on the vortex lattice structure of the rotating two-
component Bose-Einstein condensates (BECs) in the presence of impurities or disorder by …

We numerically investigate the impact of various impurities on rotating Bose–Einstein
condensates confined within two-dimensional harmonic and Gaussian distributed square …
