Wannier-Stark localization, confinement and edge states
N. Aucar Boidi, A. Aharony, O. Entin-Wohlman +1
The boundary between a system's bulk and the vacuum can be modeled by a potential which confines the electrons to the bulk. Here we present the example of the Wannier-Stark linear…
Interatomic spin-orbit interaction in a -orbital helical atomic chain
Takemitsu Kato, Yasuhiro Utsumi, Ora Entin-Wohlman +1
We derive the interatomic spin-orbit interaction (SOI) from a helical atomic chain composed of -orbitals with intra-atomic SOI, which exhibits a helical state--a potential origi…
Magnetizing weak links by time-dependent spin-orbit interactions: momentum conserving and non-conserving processes
Debashree Chowdhury, O. Entin-Wohlman, A. Aharony +2
Rashba spin-orbit interactions generated by time-dependent electric fields acting on weak links (that couple together non-magnetic macroscopic leads) can magnetize the junction. Th…
Spin-orbit interactions, time-reversal symmetry, and spin selection
Amnon Aharony, Ora Entin-Wohlman
Spin selective transport is usually associated with spin-orbit interactions. However, these interactions are invariant under time-reversal symmetry, and the Onsager relations and B…
Crossover from Wannier-Stark localization to charge density waves for interacting spinless fermions in one dimension
Nair Aucar Boidi, Amnon Aharony, Ora Entin-Wohlman +2
We study spinless fermions on a finite chain with nearest-neighbor repulsion and in the presence of a Wannier-Stark linearly-varying electric field potential. In the absence of the…
