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…
Ising model on a hyperbolic plane with a boundary
Seung Ki Baek, Harri Mäkelä, Petter Minnhagen +1
A hyperbolic plane can be modeled by a structure called the enhanced binary tree. We study the ferromagnetic Ising model on top of the enhanced binary tree using the renormalizatio…
Critical temperatures of the three- and four-state Potts models on the kagome lattice
Seung Ki Baek, Harri Mäkelä, Petter Minnhagen +1
The value of the internal energy per spin is independent of the strip width for a certain class of spin systems on two dimensional infinite strips. It is verified that the Ising mo…
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…
