Repulsive Casimir-Polder potentials of low-lying excited states of a multilevel alkali-metal atom near an optical nanofiber

Autor: Kien, Fam Le, Kornovan, D. F., Chormaic, Sile Nic, Busch, Thomas

We study the Casimir-Polder potential of a multilevel alkali-metal atom near an optical nanofiber. We calculate the mean potential of the atom in a fine-structure level. We perform numerical calculations for the Casimir-Polder potentials of the groun

Report

Extremely subradiant states in a periodic one-dimensional atomic array

Autor: Kornovan, D. F., Corzo, N. V., Laurat, J., Sheremet, A. S.

Publikováno v: Phys. Rev. A 100, 063832 (2019)

We study the subradiant collective states of a periodic chain of two-level atoms with either transversal or longitudinal transition dipole moments with respect to the chain axis. We show that long-lived subradiant states can be obtained for the trans

Self-trapped nanoparticle binding via waveguide mode

Autor: Toftul, I. D., Kornovan, D. F., Petrov, M. I.

In this paper, we study a stable optomechanical system based on a nanoparticle chain coupled to a waveguide mode. Under the plane wave excitation the nanoparticles form a stable self-organized periodic chain array along the direction of the waveguide

Non-inverse dynamics of a quantum emitter coupled to a fully anisotropic environment

Autor: Kornovan, D. F., Petrov, M. I., Iorsh, I. V.

Publikováno v: Phys. Rev. A 100, 033840 (2019)

Anisotropic nanophotonic structures can couple the levels of a quantum emitter through the quantum interference effect. In this paper we study the coupling of quantum emitters excited states through the modes of a fully anisotropic structure: a struc

Force of light on a two-level atom near an ultrathin optical fiber

Autor: Kien, Fam Le, Kornovan, D F, Hejazi, S Sahar S, Truong, Viet Giang, Petrov, M I, Chormaic, Sile Nic, Busch, Thomas

We study the force of light on a two-level atom near an ultrathin optical fiber using the mode function method and the Green tensor technique. We show that the total force consists of the driving-field force, the spontaneous-emission recoil force, an

Collective polaritonic modes in an array of two-level quantum emitters coupled to optical nanofiber

Autor: Kornovan, D. F., Sheremet, A. S., Petrov, M. I.

Publikováno v: Phys. Rev. B 94, 245416 (2016)

In this paper we develop a microscopic analysis of the light scattering on a periodic two-level atomic array coupled to an optical nanofiber. We extend the scattering matrix approach for two-level system interaction with nanofiber fundamental wavegui

Report

Coherent control of light transport in a dense and disordered atomic ensemble

Autor: Sheremet, A. S., Kornovan, D. F., Gerasimov, L. V., Gouraud, B., Laurat, J., Kupriyanov, D. V.

Publikováno v: Phys. Rev. A 91 053813 (2015)

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 alternative approach to light-matter interfacing protocols. Here, we show
