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…

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…
