[كتاب][B] The defocusing nonlinear Schrödinger equation: from dark solitons to vortices and vortex rings
PG Kevrekidis, DJ Frantzeskakis… - 2015 - SIAM
The phenomenon of Bose–Einstein condensation is a phase transition originally predicted
by Bose and Einstein in 1924. In particular, it was shown that below a critical temperature T …

Bifurcations and chaos in semiconductor superlattices with a tilted magnetic field
We study the effects of dissipation on electron transport in a semiconductor superlattice with
an applied bias voltage and a magnetic field that is tilted relative to the superlattice axis. In …
