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…
Quantum Optimal Control Theory
J. Werschnik, E. K. U. Gross
The control of quantum dynamics via specially tailored laser pulses is a long-standing goal in physics and chemistry. Partly, this dream has come true, as sophisticated pulse shapi…
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…
Orbital currents in the Colle-Salvetti correlation energy functional and the degeneracy problem
S. Pittalis, S. Kurth, S. Sharma +1
Popular density functionals for the exchange-correlation energy typically fail to reproduce the degeneracy of different ground states of open-shell atoms. As a remedy, functionals…
Comparison of exact-exchange calculations for solids in current-spin-density- and spin-density-functional theory
S. Sharma, S. Pittalis, S. Kurth +3
The relative merits of current-spin-density- and spin-density-functional theory are investigated for solids treated within the exact-exchange-only approximation. Spin-orbit splitti…
