Decay of an isolated monopole into a Dirac monopole configuration
K. Tiurev, E. Ruokokoski, H. Mäkelä +2
We study numerically the detailed structure and decay dynamics of isolated monopoles in conditions similar to those of their recent experimental discovery. We find that the core of…
Excitation spectrum of a toroidal spin-1 Bose-Einstein condensate
H. Mäkelä, E. Lundh
We calculate analytically the Bogoliubov excitation spectrum of a toroidal spin-1 Bose-Einstein condensate that is subjected to a homogeneous magnetic field and contains vortices w…
Stability of nonstationary states of spin-2 Bose-Einstein condensates
H. Mäkelä, E. Lundh
The dynamical stability of nonstationary states of homogeneous spin-2 rubidium Bose-Einstein condensates is studied. The states considered are such that the spin vector remains par…
Stability of nonstationary states of spin-1 Bose-Einstein condensates
H. Mäkelä, M. Johansson, M. Zelan +1
The stability of nonstationary states of homogeneous spin-1 Bose-Einstein condensates is studied by performing Bogoliubov analysis in a frame of reference where the state is statio…
Dissipation-induced squeezing
Gentaro Watanabe, Harri Mäkelä
We present a method for phase and number squeezing in two-mode Bose systems using dissipation. The effectiveness of this method is demonstrated by considering cold Bose gases trapp…
