Landau and dynamical instabilities of Bose-Einstein condensates with superfluid flow in a Kronig-Penney potential
Ippei Danshita, Shunji Tsuchiya
We study the elementary excitations of Bose-Einstein condensates in a one-dimensional periodic potential and discuss the stability of superfluid flow based on the Kronig-Penney mod…

Stability and excitations of solitons in 2D Bose-Einstein condensates
S. Tsuchiya, F. Dalfovo, C. Tozzo +1
The small oscillations of solitons in 2D Bose-Einstein condensates are investigated by solving the Kadomtsev-Petviashvili equation which is valid when the velocity of the soliton a…
