Generation of wave turbulence in dipolar gases driven across their phase transitions
G. A. Bougas, K. Mukherjee, S. I. Mistakidis
Ultracold quantum gases with long-range anisotropic interactions host novel exotic phases of matter, such as supersolids, exhibiting both rigid and superfluid characteristics. The…
Phases and dynamics of quantum droplets in the crossover to two-dimensions
Jose Carlos Pelayo, George Bougas, Thomás Fogarty +2
We explore the ground states and dynamics of ultracold atomic droplets in the crossover region from three to two dimensions by solving the two-dimensional and the quasi two-dimensi…
Density effects on the interferometry of Efimov states by modulating magnetic fields
G. Bougas, S. I. Mistakidis, P. Giannakeas
Dynamical association of Efimov trimers in thermal gases by means of modulated magnetic fields has proven very fruitful in determining the binding energy of trimers. The latter was…
Stability and dynamics of nonlinear excitations in a two-dimensional droplet-bearing environment
G. Bougas, G. C. Katsimiga, P. G. Kevrekidis +1
We unravel stationary states in the form of dark soliton stripes, bubbles, and kinks embedded in a two-dimensional droplet-bearing setting emulated by an extended Gross-Pitaevskii…
Generic transverse stability of kink structures in atomic and optical nonlinear media with competing attractive and repulsive interactions
S. I. Mistakidis, G. Bougas, G. C. Katsimiga +1
We demonstrate the existence and stability of one-dimensional (1D) topological kink configurations immersed in higher-dimensional bosonic gases and nonlinear optical setups. Our an…
Impact of dark states on the stationary properties of quantum particles with off-centered interactions in one dimension
G. Bougas, N. L. Harshman, P. Schmelcher
We present a generalization of the two-body contact interaction for non-relativistic particles trapped in one dimension. The particles interact only when they are a distance c apar…
