Dissipative preparation of phase- and number-squeezed states with ultracold atoms
Roland Cristopher F. Caballar, Sebastian Diehl, Harri Mäkelä +2
We develop a dissipative quantum state preparation scheme for the creation of phase- and number-squeezed states. It utilizes ultracold atoms in a double-well configuration immersed…
Effects of the rotating wave and secular approximations on non-Markovianity
H. Mäkelä, M. Möttönen
We study the effect of the rotating-wave approximation (RWA) and the secular approximation (SA) on the non-Markovian behavior in the spin-boson model at zero-temperature. We find t…
Floquet analysis of the modulated two-mode Bose-Hubbard model
Gentaro Watanabe, Harri Mäkelä
We study the tunneling dynamics in a time-periodically modulated two-mode Bose-Hubbard model using Floquet theory. We consider situations where the system is in the self-trapping r…
Parametrizations of density matrices
E. Brüning, H. Mäkelä, A. Messina +1
This article gives a brief overview of some recent progress in the characterization and parametrization of density matrices of finite dimensional systems. We discuss in some detail…
Interferometry using spinor Bose-Einstein condensates
R. Vasile, H. Makela, K. -A. Suominen
We study the time-evolution of an optically trapped spinor Bose-Einstein condensate under the influence of a dominating magnetic bias field in the z-direction, and a perpendicular…
Ground states of spin-3 Bose-Einstein condensates for conserved magnetization
Harri Mäkelä, Kalle-Antti Suominen
We calculate the ground states and ground state phase diagrams of Bose-Einstein condensates of spin-3 atoms under the assumption of conserved magnetization. We especially concentra…
