Creation and dynamics of two-dimensional skyrmions in antiferromagnetic spin-1 Bose-Einstein condensates
T. Ollikainen, E. Ruokokoski, M. Möttönen
We numerically simulate the creation process of two-dimensional skyrmionic excitations in antiferromagnetic spin-1 Bose--Einstein condensates by solving the full three-dimensional…
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…
Highly Controllable Qubit-Bath Coupling Based on a Sequence of Resonators
P. J. Jones, J. Salmilehto, M. Möttönen
Combating the detrimental effects of noise remains a major challenge in realizing a scalable quantum computer. To help to address this challenge, we introduce a model realizing a c…
Distribution of Entropy Production in a Single-Electron Box
J. V. Koski, T. Sagawa, O. -P. Saira +6
Recently, the fundamental laws of thermodynamics have been reconsidered for small systems. The discovery of the fluctuation relations has spurred theoretical and experimental studi…
Tunable electromagnetic environment for superconducting quantum bits
P. J. Jones, J. A. M. Huhtamäki, J. Salmilehto +2
We introduce a setup which realises a tunable engineered environment for experiments in circuit quantum electrodynamics. We illustrate this concept with the specific example of a q…
