Pfaffian and fragmented states at nu=5/2 in quantum Hall droplets
H. Saarikoski, E. Tolo, A. Harju +1
When a gas of electrons is confined to two dimensions, application of a strong magnetic field may lead to startling phenomena such as emergence of electron pairing. According to a…
Local correlation functional for electrons in two dimensions
S. Pittalis, E. Rasanen, M. Marques
We derive a local approximation for the correlation energy in two-dimensional electronic systems. In the derivation we follow the scheme originally developed by Colle and Salvetti…
Electron localization function for two-dimensional systems
E. Rasanen, A. Castro, E. K. U. Gross
The concept of the electron localization function (ELF) is extended to two-dimensional (2D) electron systems. We show that the topological properties of the ELF in 2D are considera…
Spin-droplets in confined quantum Hall systems
E. Rasanen, H. Saarikoski, A. Harju +2
Two-dimensional semiconductor quantum dots are studied in the the filling-factor range 2<v<3. We find both theoretical and experimental evidence of a collective many-body phenomeno…
Exchange-energy functionals for finite two-dimensional systems
S. Pittalis, E. Rasanen, N. Helbig +1
Implicit and explicit density functionals for the exchange energy in finite two-dimensional systems are developed following the approach of Becke and Roussel [Phys. Rev. A 39, 3761…
Optimal laser-control of double quantum dots
E. Rasanen, A. Castro, J. Werschnik +2
Coherent single-electron control in a realistic semiconductor double quantum dot is studied theoretically. Using optimal-control theory we show that the energy spectrum of a two-di…
