Bright solitons in quasi-one dimensional dipolar condensates with spatially modulated interactions / Abdullaev, Fatkhulla Kh ; Gammal, Arnaldo ; Malomed, Boris A ; Tomio, Lauro
We introduce a model for the condensate of dipolar atoms or molecules, in which the dipole-dipole interaction (DDI) is periodically modulated in space, due to a periodic change of the local orientation of the permanent dipoles, imposed by the corresponding structure of an external field (the necessary field can be created, in particular, by means of magnetic lattices, which are available to the experiment).

Direct Numerical Simulation of Electrokinetic Instability and Transition to Chaotic Motion / Demekhin, E A ; Nikitin, N V ; Shelistov, V S
A new type of instability - electrokinetic instability - and an unusual transition to chaotic motion near a charge-selective surface was studied by numerical integration of the Nernst-Planck-Poisson-Stokes system and a weakly nonlinear analysis near the threshold of instability. [...]
