Single-particle theory of persistent spin helices in two-dimensional electron gas: the general approach for quantum wells with different growth direction

Autor: Kozulin, Alexander S., Malyshev, Alexander I., Konakov, Anton A.

We present a detailed theoretical investigation of persistent spin helices in two-dimensional electron systems with spin-orbit coupling. For this purpose we consider a single-particle effective mass Hamiltonian with generalized linear-in-k spin-orbit

Spin Chaos Manifestation in a Driven Quantum Billiard with Spin-Orbit Coupling

Autor: Khomitsky, D. V., Malyshev, A. I., Sherman, E. Ya., Di Ventra, M.

Publikováno v: Physical Review B 88, 195407 (2013)

The coupling of orbital and spin degrees of freedom is the source of many interesting phenomena. Here, we study the electron dynamics in a quantum billiard --a mesoscopic rectangular quantum dot-- with spin-orbit coupling driven by a periodic electri

Nonlinear electron dynamics in a rippled channel with time-dependent electric field: Quantum Arnol'd diffusion

Autor: Demikhovskii, V. Ya., Izrailev, F. M., Malyshev, A. I.

We study the electron dynamics in a 2D waveguide bounded by a periodically rippled surface in the presence of the time-periodic electric field. The main attention is paid to a possibility of a weak quantum diffusion along the coupling resonance, that

Quantum Arnol'd diffusion in a rippled waveguide

Autor: Demikhovskii, V. Ya., Izrailev, F. M., Malyshev, A. I.

Publikováno v: Phys. Lett. A 352 (2006) 491

We study the quantum Arnol'd diffusion for a particle moving in a quasi-1D waveguide bounded by a periodically rippled surface, in the presence of the time-periodic electric field. It was found that in a deep semiclassical region the diffusion-like m

Quantum Arnol'd Diffusion in a Simple Nonlinear System

Autor: Demikhovskii, V. Ya., Izrailev, F. M., Malyshev, A. I.

Publikováno v: Phys.Rev. E66 (2002) 036211

We study the fingerprint of the Arnol'd diffusion in a quantum system of two coupled nonlinear oscillators with a two-frequency external force. In the classical description, this peculiar diffusion is due to the onset of a weak chaos in a narrow stoc

Report

Manifestation of the Arnol'd Diffusion in Quantum Systems

Autor: Demikhovskii, V. Ya., Izrailev, F. M., Malyshev, A. I.

Publikováno v: Phys. Rev. Lett. 88 (2002) 154101

We study an analog of the classical Arnol'd diffusion in a quantum system of two coupled non-linear oscillators one of which is governed by an external periodic force with two frequencies. In the classical model this very weak diffusion happens in a
