Observation of the single-electron regime in a highly tunable silicon quantum dot
W. H. Lim, F. A. Zwanenburg, H. Huebl +4
We report on low-temperature electronic transport measurements of a silicon metal-oxide-semiconductor quantum dot, with independent gate control of electron densities in the leads…
Splitting dynamics of giant vortices in dilute Bose-Einstein condensates
Pekko Kuopanportti, Mikko Möttönen
We study the splitting of multiply quantized vortices with large quantum numbers in dilute nonrotated Bose-Einstein condensates in the zero-temperature limit. The splitting is obse…
Decoherence in adiabatic quantum evolution - application to Cooper pair pumping
J. P. Pekola, V. Brosco, M. Mottonen +2
One of the challenges of adiabatic control theory is the proper inclusion of the effects of dissipation. Here, we study the adiabatic dynamics of an open two-level quantum system d…
Probe and Control of the Reservoir Density of States in Single-Electron Devices
M. Mottonen, K. Y. Tan, K. W. Chan +11
We present a systematic study of quasi-one-dimensional density of states (DOS) in electron accumulation layers near a Si-SiO2 interface. In the experiments we have employed two con…
Finite-temperature phase transitions in quasi-two-dimensional spin-1 Bose gases
Ville Pietilä, Tapio P. Simula, Mikko Möttönen
Recently, the Berezinskii-Kosterlitz-Thouless transition was found to be mediated by half-quantum vortices (HQVs) in two-dimensional (2D) antiferromagnetic Bose gases [Phys. Rev. L…
Core sizes and dynamical instabilities of giant vortices in dilute Bose-Einstein condensates
Pekko Kuopanportti, Emil Lundh, Jukka A. M. Huhtamäki +2
Motivated by a recent demonstration of cyclic addition of quantized vorticity into a Bose-Einstein condensate, the vortex pump, we study dynamical instabilities and core sizes of g…
