Phase-Controlled Absorption and Dispersion Properties of a Multi-Level Quantum Emitter Interacting with Bismuth-Chalcogenide Microparticles

Photonics, 2023
We theoretically study the impact of bismuth-chalcogenide microparticles on the linear absorption and dispersion properties of a four-level double-V-type quantum system.

Exercise training corrects control of spontaneous calcium waves in hearts from myocardial infarction heart failure rats [PDF]

, 2011
Impaired cardiac control of intracellular diastolic Ca²⁺ gives rise to arrhythmias. Whereas exercise training corrects abnormal cyclic Ca²⁺ handling in heart failure, the effect on diastolic Ca<sup>2 ...

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Spontaneous emission from excited quantum kinks

Journal of High Energy Physics, 2022
Many kink solutions enjoy internal excitations, called shape modes. In some 1+1d scalar models, such as the ϕ 4 double-well model, when a kink’s shape mode is excited twice it may decay to a ground state kink plus a meson.

Simulations of the spontaneous emission of a quantum dot near a gap plasmon waveguide

, 2014
In this paper we modeled a quantum dot at near proximity to a gap plasmon waveguide to study the quantum dot-plasmon interactions. Assuming that the waveguide is single mode, this paper is concerned about the dependence of spontaneous emission rate of ...

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

Advanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.

Strong Coupling Dynamics of a Quantum Emitter near a Topological Insulator Nanoparticle

Nanomaterials, 2023
We study the spontaneous emission dynamics of a quantum emitter near a topological insulator Bi2Se3 spherical nanoparticle. Using the electromagnetic Green’s tensor method, we find exceptional Purcell factors of the quantum emitter up to 1010 at ...

Electromagnetically induced phase grating controlled by spontaneous emission

, 2012
Electromagnetically induced phase grating controlled by spontaneous emission is studied. The results show that the diffraction efficiency of phase grating is strikingly enhanced due to the existence of spontaneously generated coherence (SGC), and the ...

Benchmarking the Cumulant Expansion Method Using Dicke Superradiance

Photonics
Collective superradiant decay of a tightly packed inverted quantum emitter ensemble is among the most intensely studied phenomena in quantum optics. Since the seminal work of Dicke more than half a century ago, a plethora of theoretical calculations in ...
