Influence of dipole-dipole interaction and detuning on the entanglement of two qubits induced by a thermal field

open access: yesФизика волновых процессов и радиотехнические системы, 2017
In this paper we have investigated the dynamics of entanglement of two identical qubits nonresonantly interacting with one mode of a thermal electromagnetic field in lossless resonator in the presence of a direct dipole-dipole interaction.

Red emission in MoO3:Eu3+ nanobelts: Investigation on the photoluminescence quenching mechanism

open access: yesChemical Physics Impact
MoO3:Eu3+ nanobelts were synthesized via the hydrothermal method with varying concentrations of europium doping. The investigation has examined the structural, morphological, optical, and photoluminescence characteristics of MoO3:Eu3+ nanophosphors.

Distribution of Exchange Interaction Fields for 2D and 3D Systems of Spherical Dipoles [PDF]

open access: yesЖурнал нано- та електронної фізики, 2014
By the method of numerical simulation have been shown that the dipole-dipole interaction in the high-anisotropic spherical magnetic dipole moments can result in the case of the particle distribution on the plane to poorly defined ferromagnetism, and for ...

IMPACT OF DIPOLE-DIPOLE INTERACTION ON THE CAVITY MODE EVOLUTION IN THE MODEL OF FEW EMITTERS LASER

open access: yesSt. Petersburg Polytechnical University Journal: Physics and Mathematics, 2019
In the paper, the simple model of а two-atom laser is theoretically studied. The both dipole-dipole coupled atoms are under conditions of incoherent pump, are placed into the Fabry – Perot cavity and interact with a single damping field mode.

A dipole band above the Iπ= 31/2− isomeric state in 189Pb

open access: yesEPJ Web of Conferences, 2016
This contribution focuses on the new observation of a dipole band built upon an Iπ=31/2− isomeric state in 189Pb, identified using recoil-isomer tagging at the University of Jyväskylä, Finland.

Dynamics of entanglement of two dipole-coupled Josephson qubits interacting with two lossless resonators

open access: yesФизика волновых процессов и радиотехнические системы, 2016
In the present paper we investigated the dynamics of two dipole-coupled superconducting qubits prepared in an entangled state and interacting with two modes of the vacuum electromagnetic fields of two independent resonators.

Quantum dynamics of spin-J particles in static and rotating magnetic fields: entanglement resonances and kinks

open access: yesNew Journal of Physics
We examine the quantum dynamics of both a single spin- J particle and a pair of spin- J particles in the presence of static and rotating magnetic fields, which can be important for qudit-based quantum technologies.

Charge-dipole-dipole interactions in cold gases

open access: yesAcademia Quantum
Charge-dipole interactions are very common interactions among atoms and molecules, especially materials that can emit light or contain free charges. The second-order charge-dipole interactions, proportional to

Mirror symmetry breaking of superradiance in a dipolar Bose-Einstein condensate

open access: yesPhysical Review Research
Dicke superradiance occurs when two or more emitters cooperatively interact via the electromagnetic field. This collective light-scattering process has been extensively studied across various platforms, from atoms to quantum dots and organic molecules ...
