Cotunneling current through quantum dots with phonon-assisted spin-flip processes
Jörg Lehmann, Daniel Loss
We consider cotunneling through a quantum dot in the presence of spin-flip processes induced by the coupling to acoustic phonons of the surrounding. An expression for the phonon-as…
Singlet-triplet decoherence due to nuclear spins in a double quantum dot
W. A. Coish, Daniel Loss
We have evaluated hyperfine-induced electron spin dynamics for two electrons confined to a double quantum dot. Our quantum solution accounts for decay of a singlet-triplet correlat…
Anisotropic states of two-dimensional electrons in high magnetic fields
A. M. Ettouhami, C. B. Doiron, F. D. Klironomos +2
We study the collective states formed by two-dimensional electrons in Landau levels of index near half-filling. By numerically solving the self-consistent Hartree-Fock (HF…
Spin relaxation and decoherence of holes in quantum dots
Denis V. Bulaev, Daniel Loss
We investigate heavy-hole spin relaxation and decoherence in quantum dots in perpendicular magnetic fields. We show that at low temperatures the spin decoherence time is two times…
Entanglement in SU(2)-invariant quantum systems: The positive partial transpose criterion and others
John Schliemann
We study entanglement in mixed bipartite quantum states which are invariant under simultaneous SU(2) transformations in both subsystems. Previous results on the behavior of such st…
Coulomb distortion of relativistic electrons in the nuclear electrostatic field
Andreas Aste, Cyrill von Arx, Dirk Trautmann
Continuum states of the Dirac equation are calculated numerically for the electrostatic field generated by the charge distribution of an atomic nucleus. The behavior of the wave fu…
