      Evolution of a Bose-Einstein condensate in a rapidly expanding circular box 

      Theodorakis, Stavros; Constantinou, Y. (2007)
      We examine the evolution of the ground state of a Bose-Einstein condensate in a two-dimensional circular box, the wall of which is initially at rest and then recedes with large and constant speed. The final state of the ...

      Non-peturbative density expansions for extended Coulomb systems 

      Moulopoulos, Konstantinos (2000)

      Piecewise analytic approximation for Bose-Einstein condensates in isotropic harmonic traps 

      Theodorakis, Stavros (2004)
      Analytic simulacra of the wave functions in the regions around the origin and far from the origin were constructed to emulate the ground state and the single-vortex state of a Bose-Einstein condensate in an isotropic ...

      Piecewise linear emulator of the nonlinear Schrödinger equation and the resulting analytic solutions for Bose-Einstein condensates 

      Theodorakis, Stavros (2003)
      A most general method for finding very good analytic approximate solutions to the cubic nonlinear Schrodinger equation is presented. This method applies whenever the nonlinearity in that equation is a purely cubic one. It ...
