Linear “ship waves” generated in stationary flow of a Bose-Einstein condensate past an obstacle
نویسندگان
چکیده
Using stationary solutions of the linearized two-dimensional Gross-Pitaevskii equation, we describe the “ship wave” pattern occurring in the supersonic flow of a Bose-Einstein condensate past an obstacle. It is shown that these “ship waves” are generated outside the Mach cone. The developed analytical theory is confirmed by numerical simulations of the flow past body problem in the frame of the full non-stationary Gross-Pitaevskii equation.

متن کاملGeneration of linear waves in the flow of Bose - Einstein condensate past an obstacle
The theory of linear wave structures generated in Bose-Einstein condensate flow past an obstacle is developed. The shape of wave crests and dependence of amplitude on coordinates far enough from the obstacle are calculated. The results are in good agreement with the results of numerical simulations obtained earlier. The theory gives a qualitative description of experiments with Bose-Einstein co...
متن کاملTwo-dimensional periodic waves in supersonic flow of a Bose–Einstein condensate
Stationary periodic solutions of the two-dimensional Gross–Pitaevskii equation are obtained and analysed for different parameter values in the context of the problem of a supersonic flow of a Bose–Einstein condensate past an obstacle. The asymptotic connections with the corresponding periodic solutions of the Korteweg–de Vries and nonlinear Schrödinger equations are studied and typical spatial ...

متن کاملGeneration of oblique dark solitons in supersonic flow of Bose-Einstein condensate past an obstacle
Nonlinear and dispersive properties of Bose-Einstein condensate (BEC) provide a possibility of formation of various nonlinear structures such as vortices and bright and dark solitons (see, e.g., [1]). Yet another type of nonlinear wave patterns has been observed in a series of experiments on the BEC flow past macroscopic obstacles [2]. In [3] these structures have been associated with spatial d...
