Numerical exploration of vortex matter in Bose-Einstein condensates
We describe finite element numerical approach to the full Hartree-Fock-Bogohubov treatment of a vortex lattice in a rapidly rotating Bose-Einstein condensate. We study the system in the regime of high thermal or significant quantum fluctuations where we are presented with a very large nonlinear unsymmetric eigenvalue problem which is indefinite and which possesses low-lying excitation clustered arbituarily close to zero a problem that requires state-of the-art numerical techniques.
