Excitation spectrum of a multilevel atom coupled with a dielectric nanostructure
N. A. Moroz, L. V. Gerasimov, A. D. Manukhova +1
We develop a microscopic calculation scheme for the excitation spectrum of a single-electron atom localized near a dielectric nanostructure. The atom originally has an arbitrary de…
Spatial dependence of fidelity for a two-qubit Rydberg-blockade quantum gate
Ivan Vybornyi, Leonid Gerasimov, Dmitriy Kupriyanov +2
We study the spatial performance of the entangling gate proposed by H. Levine et al. (Phys. Rev. Lett. 123, 170503 (2019)). This gate is based on a Rydberg blockade technique and c…
Coupled dynamics of spin qubits in optical dipole microtraps
L. V. Gerasimov, R. R. Yusupov, A. D. Moiseevsky +6
Single atoms in dipole microtraps or optical tweezers have recently become a promising platform for quantum computing and simulation. Here we report a detailed theoretical analysis…
Dynamics of a spin qubit in an optical dipole trap
L. V. Gerasimov, R. R. Yusupov, I. B. Bobrov +5
We present a theoretical investigation of coherent dynamics of a spin qubit encoded in hyperfine sublevels of an alkali-metal atom in a far off-resonant optical dipole trap. The qu…
Single collective excitation of an atomic array trapped along a waveguide: a study of cooperative emission for different atomic chain configurations
V. A. Pivovarov, L. V. Gerasimov, J. Berroir +4
Ordered atomic arrays trapped in the vicinity of nanoscale waveguides offer original light-matter interfaces, with applications to quantum information and quantum non-linear optics…
Quantum interface between light and a one-dimensional atomic system
Viacheslav A. Pivovarov, Alexandra S. Sheremet, Leonid V. Gerasimov +2
We investigate optimal conditions for the quantum interface between a signal photon pulse and one-dimensional chain consisting of a varied number of atoms. The tested object is phy…
Raman sideband cooling of a single atom in an optical dipole trap: Towards theoretical optimum in a three-dimensional regime
V. M. Porozova, L. V. Gerasimov, I. B. Bobrov +3
We clarify the optimal conditions for the protocol of Raman sideband cooling (RSC) of a single atom confined with a tightly focused far-off-resonant optical dipole trap (optical tw…
Light scattering from an atomic gas under conditions of quantum degeneracy
V. M. Porozova, L. V. Gerasimov, M. D. Havey +1
We consider a quantum theory of elastic light scattering from a macroscopic atomic sample existing in the Bose-Einstein condensate (BEC) phase. The dynamics of the optical excitati…
Light Scattering From an Atomic Array Trapped Near a One-Dimensional Nanoscale Waveguide: a Microscopic Approach
V. A. Pivovarov, A. S. Sheremet, L. V. Gerasimov +4
The coupling of atomic arrays and one-dimensional subwavelength waveguides gives rise to in- teresting photon transport properties, such as recent experimental demonstrations of la…
Random Lasing in an Inhomogeneous and Disordered System of Cold Atoms
L. V. Gerasimov, D. V. Kupriyanov, M. D. Havey
We consider light trapping in an amplifying medium consisting of cold alkali-metal atoms; the atomic gas plays a dual role as a scattering and as a gain medium. We perform Monte-Ca…
Coherent control of light transport in a dense and disordered atomic ensemble
A. S. Sheremet, D. F. Kornovan, L. V. Gerasimov +3
Light transport in a dense and disordered cold atomic ensemble, where the cooperation of atomic dipoles essentially modifies their coupling with the radiation modes, offers an alte…

We consider the Raman process developing in a disordered medium of alkali-metal atoms when the scattered modes are trapped on a closed transition. Our theoretical analysis, based o…

In the present paper we consider a quantum memory scheme for light diffusely propagating through a spatially disordered atomic gas. The diffuse trapping of the signal light pulse c…
Quantum memory for light via stimulated off-resonant Raman process: beyond the three-level Lambda-scheme approximation
Alexandra S. Sheremet, Leonid V. Gerasimov, Igor M. Sokolov +4
We consider a quantum memory scheme based on the conversion of a signal pulse into a long-lived spin coherence via stimulated off-resonant Raman process. For a storing medium consi…
Coherent control of diffuse light dynamics in an ultracold atomic gas
L. V. Gerasimov, I. M. Sokolov, D. V. Kupriyanov +2
We show that coherent multiple light scattering, or diffuse light propagation, in a disordered atomic medium, prepared at ultra-low temperatures, can be be effectively delayed in t…
