Аннотация:
We show that spin precession in a semiconductor quantum wire, caused by the Rashba and the Dresselhaus interactions (both of arbitrary strengths), can be suppressed by dint of an in-plane
magnetic
field. Using a condition of the translational invariance in the longitudinal coordinate, we found another type of symmetry, which arises at a particular set of intensity and orientation of the
magnetic
field and explains this suppression. Based on our findings, we propose a transport experiment to measure the strengths of the Rashba and the Dresselhaus interactions.

Аннотация:
This paper introduces a semi-analytical method for calculating the Hall conductivity in the single-band approximation. The method goes beyond the linear response theory and thus, it formally imposes no limitation on the electric-field magnitude. It is shown that, when the Bloch frequency exceeds the cyclotron frequency, the Hall current decreases with increasing electric field. The obtained results can be directly applied to the cold Bose atoms in a 2D optical lattice, where the single-band approximation is well justified. Copyright (C) EPLA, 2011

Quantum dynamics of a charged particle in a two-dimensional (2D) lattice subject to
magnetic
and electric
fields
is a rather complicated interplay between cyclotron oscillations (the case of vanishing electric field) and Bloch oscillations (zero
magnetic
field), details of which has not yet been completely understood. In the present work we suggest to study this problem by using cold atoms in optical lattices. We introduce a one-dimensional (1D) model which can be easily realized in laboratory experiments with quasi-1D optical lattices and show that this model captures many features of the cyclotron-Bloch dynamics of the quantum particle in 2D square lattices.

Аннотация:
We analyze the driven Harper model, which appears in the problem of tight-binding electrons in the Hall configuration (normal to the lattice plane
magnetic
field plus in-plane electric field). The presence of an electric field extends the celebrated Harper model, which is parametrized by the Peierls phase, into the driven Harper model, which is additionally parametrized by two Bloch frequencies, associated with the two components of the electric field. We show that the eigenstates of the driven Harper model are either extended or localized, depending on the commensurability of the Bloch frequencies. This results holds for both rational and irrational values of the Peierls phase. In the case of incommensurate Bloch frequencies we provide an estimate for the wave-function localization length.

Аннотация:
We study the quantum dynamics of a charged particle in a two-dimensional lattice, subject to constant and homogeneous electric and
magnetic
fields
. We find that different regimes characterize these motions, depending on a combination of conditions, corresponding to weak and strong electric field intensities, rational or irrational directions of the electric field with respect to the lattice, and small or large values of the
magnetic
(Peierls) phase.

Аннотация:
We study the interband Landau-Zener tunnelling of a quantum particle in the Hall configuration, i.e., in the presence of gauge field (for example,
magnetic
field for a charged particle) and in-plane potential field (electric field for a charged particle) normal to the lattice plane. The interband tunnelling is induced by the potential field and for the vanishing gauge field is described by the common Landau-Zener theory. We generalize this theory for a nonzero gauge field. The depletion rates of low-energy bands are calculated by using a semi-analytical method of the truncated Floquet matrix.
