Abstract By numerical propagation of the coupled Gross-Pitaevskii equations, ground state phase a SU(3) spin-orbit Bose gas with nonlocal soft-core interactions has been investigated within all parameter space, showing strong dependence on strength coupling, interactions, spin-exchange and Rydberg blockade radius. More specially, we also perform detailed study interaction radius at point rotational symmetry breaking. Our results show that under combined effects such parameters, shows...
Abstract Vortex shedding from a moving obstacle potential in two-component Bose–Einstein condensate is investigated numerically. For miscible composed of 23 Na and 87 Rb atoms, the wake obstacle, Kármán vortex street discovered one component, while Kármán-like named ‘half-quantum street’ formed another component. The other patterns shedding, such as dipoles, V-shaped pairs corresponding shedding’, can also be found. drag force acting on calculated discussed. parameter region for various...
We consider a magnetized dusty plasma, which composed of low-temperature and high-temperature ions, electrons, dust particles. The dynamical behaviors can be described by (3+1)-dimensional Zakharov-Kuznetsov equation (ZKE). Interestingly, type completely localized solitary waves, are different from the line solitons, ZKE obtained analytically approximately for first time. This kind wave is also confirmed numerically Petviashvili method. Both analytical numerical results indicate that...
We study the gap solitons and their stability properties in a Bose-Einstein condensation (BEC) under three-body interaction loaded Jacobian elliptic sine potential, which can be described by cubic-quintic Gross-Pitaevskii equation (GPE) mean-field approximation. Firstly, GPE is transformed into stationary nonlinear Schrödinger (NLSE) multi-scale method. A class of analytical solution NLSE presented to describe solitons. It shown analytically that amplitude soliton decreases as two-body or...
The dynamics of pseudo-spin-1/2 Bose-Einstein condensates with weak spin-orbit coupling through a moving obstacle potential are studied numerically. Four types wakes observed and the phase diagrams determined for different strengths. conditions to form B\'enard--von K\'arm\'an vortex street rather rigorous, we investigate in detail dynamical characteristics streets. two point vortices pair rotate around their center, angular velocity distance oscillate periodically. oscillation intensifies...
We consider the ground state of Rydberg-dressed Bose gas with spin–orbit coupling and confined in a two-dimensional optical lattice. The effects system’s parameters, especially nonlocal Rydberg interaction coupling, on ground-state structure such system are explored full parameter space. It is found that absence changes from initial lattice to periodic one cell size decreasing strength interaction. In presence both phase internal unit show strong dependence coupling. Finally, interacting...
We numerically investigate the nonlinear waves propagating in a one-dimensional particle chain when damping effect is taken into account. It found that decaying solitary exist, which amplitude of wave decreases exponentially as time increases. Meanwhile, velocity also slows down goes. This result implies coefficient an important parameter such system. Theoretical analysis has been done by reductive perturbation method. The indicates system can be described damped KdV equation.
Bénard-von Kármán vortex street in dipolar Bose-Einstein Condensate (BEC) trapped by a square-like potential is investigated numerically. In the frame of mean-field theory, nonlinear dynamic BEC can be described so-called two-dimensional Gross-Pitaevskii (GP) equation with long-range interaction. this paper, we only consider case that all dipoles are polarized along <i>z</i>-axis, which perpendicular to plane disc-shaped BEC. Firstly, stationary state obtained imaginary-time...
The three dimensional nonlinear viscoelastic artificial boundary is deduced based on the principle that stress equals to of media with standard linear solid model. numerical examples show this proposed high accuracy in simulating radiation damping
The experimental realization of Rydberg dressing and spin-orbit coupling greatly broadens the research field ultracold atoms as a quantum simulation platform. Very recently, moiré lattices have attracted intensive study, ranging from condensed matter to physics. In this paper, ground-state structure Rydberg-dressed Bose gas with confined in is studied, effects nonlocal interaction on ground state system are explored. Our results show that has no translational symmetry due presence...
With the continuous development of endovascular surgery, thoracic aortic repair (TEVAR) has gradually replaced traditional open surgery and become preferred treatment strategy for Stanford type B dissection. However, disadvantage short proximal landing zone greatly limited indication TEVAR affected prognosis. In recent years, many strategies such as hybrid in vitro fenestrated branched endo-graft, chimney technique, in-situ fenestration etc., have been developed, which broadens improved...
