Intersubband-induced spin-orbit interaction in quantum wells
Rafael S. Calsaverini, Esmerindo Bernardes, J. Carlos Egues +1
Recently, we have found an additional spin-orbit (SO) interaction in quantum wells with two subbands [Phys. Rev. Lett. 99, 076603 (2007)]. This new SO term is non-zero even in symm…
Spin decoherence of a heavy hole coupled to nuclear spins in a quantum dot
Jan Fischer, W. A. Coish, D. V. Bulaev +1
We theoretically study the interaction of a heavy hole with nuclear spins in a quasi-two-dimensional III-V semiconductor quantum dot and the resulting dephasing of heavy-hole spin…
AC magnetization transport and power absorption in non-itinerant spin chains
Bjoern Trauzettel, Pascal Simon, Daniel Loss
We investigate the ac transport of magnetization in non-itinerant quantum systems such as spin chains described by the XXZ Hamiltonian. Using linear response theory, we calculate t…
Simulation of Many-Body Hamiltonians using Perturbation Theory with Bounded-Strength Interactions
Sergey Bravyi, David P. DiVincenzo, Daniel Loss +1
We show how to map a given n-qubit target Hamiltonian with bounded-strength k-body interactions onto a simulator Hamiltonian with two-body interactions, such that the ground-state…
Nuclear spin dynamics and Zeno effect in quantum dots and defect centers
D. Klauser, W. A. Coish, Daniel Loss
We analyze nuclear spin dynamics in quantum dots and defect centers with a bound electron under electron-mediated coupling between nuclear spins due to the hyperfine interaction ("…
