Transfer of correlations from photons to electron excitations and currents induced in semiconductor quantum wells by non-classical twisted light

Abstract

In this paper the excitations of collective electronic modes and currents induced in nanostructured semiconductor systems by two-mode quantum light with non-zero orbital angular momenta are investigated. Transfer of photon correlations to the excitations and currents induced in the semiconductor system is demonstrated. Birth of correlated electrons arising in the conduction band of the nanostructure due to the interaction with correlated photons of quantum light is found. Azimuthal and radial spatial distributions of the entangled electrons are established. The obtained results make possible to register the correlated electrons experimentally and to implement quantum information and nanoelectronics circuits in nanosystems using the found azimuthal and radial electron entanglement.

Peculiarities of Electron Wave Packet Dynamics in Planar Nanostructures in the Presence of Magnetic and Electric Fields

“…Generally, to prepare a localized electron wave packet in a nanosructure is a separate and rather difficult problem. However, recent theoretical investigations [32,33] show that the creation of an electron in the conductive band induced by few-photon quantum field is possible in the vicinity of a certain energy and corresponds to a superposition or wave packet of momentum states with a distribution close to the Gaussian distribution. For this reason, starting from the initial state (11) seems to be reasonable.…”

Excitation of Semiconductor Nanosystems by Multy-Frequency Quantum Field

“…Nanostructured systems are characterized by interesting quantum features arising due to the effects of spatial quantization. At the same time, the interaction with electromagnetic fields opens up a wide range of possibilities to develop methods for controlling spatially localized excitations and current [1][2][3][4][5][6][7][8][9][10] in such structures and to use them for purposes of nanoelectronics and of quantum information algorithms. One of the relevant areas of such research is the investigation of the impact of non-classical fields since the experimental generation of different non-classical states of electromagnetic field becomes now possible [11][12][13][14][15][16].…”

Peculiarities of exciton formation in 2D semiconductor nanostructures induced by quantum electromagnetic field under nonlinear self-phase modulation

“…candidates for using in nanoelectronics and development of quantum information technology similar to quantum information algorithms already implemented with photons. One of important directions of this scientific research consists in study of so-called hybrid systems and creation of the quantum light-matter interface which allows to couple together the quantum properties of photons and electrons in nanostructures [1][2][3][4][5][6][7][8][9][10]. For this reason the interaction of the nanosized systems with non-classical light is an important and relevant problem.…”
