Deterministic Nanofabrication of Quantum Dot ‐ Circular Bragg Grating Resonators with High Process Yield Using In Situ Electron Beam Lithography

Advanced Quantum Technologies, EarlyView.
We demonstrate that deterministic in situ electron‐beam lithography enables precise integration of single quantum dots into compact circular Bragg grating resonators, achieving high extraction efficiency with only 3–4 rings. Across 95 devices, the approach delivers >$>$90% alignment yield and bright, narrow‐linewidth single‐photon emission, providing a

Sign-Changing Photon-Mediated Atom Interactions in Multimode Cavity Quantum Electrodynamics. [PDF]

Physical Review Letters, 2018
Sign-changing interactions constitute a crucial ingredient in the creation of frustrated many-body systems such as spin glasses. We present here the demonstration of a photon-mediated sign-changing interaction between Bose-Einstein-condensed atoms in a ...

Integrated Metallo‐Dielectric 3D Hotspots From High Refractive Index Nanodiamond‐Plasmonic Gold Cryosoret Nano‐Assemblies for Photonic Crystal Enhanced Fluorescence

Advanced Functional Materials, Volume 36, Issue 5, 15 January 2026.
This work presents a novel sensing platform using metallo‐dielectric cryosoret nano‐assemblies and lossless photonic crystals to overcome limitations of conventional plasmonic biosensors. The hybrid system enhances both electric and magnetic field interactions, enabling amplified fluorescence, ultralow detection limits, and prism‐free, objective‐free ...

Cavity Quantum Electrodynamics of Continuously Monitored Bose-Condensed Atoms

Atoms, 2015
We study cavity quantum electrodynamics of Bose-condensed atoms that are subjected to continuous monitoring of the light leaking out of the cavity. Due to a given detection record of each stochastic realization, individual runs spontaneously break the ...

Spontaneous emission in micro- or nanophotonic structures

PhotoniX, 2021
Single-photon source in micro- or nanoscale is the basic building block of on-chip quantum information and scalable quantum network. Enhanced spontaneous emission based on cavity quantum electrodynamics (CQED) is one of the key principles of realizing ...

Beyond Conventional Cooling: Advanced Micro/Nanostructures for Managing Extreme Heat Flux

Advanced Materials, Volume 38, Issue 5, 22 January 2026.
This review examines the design, application, and manufacturing of biomimetic or engineered micro/nanostructures for managing high heat‐flux in multi‐level electronics by enhancing conductive, convective, phase‐changing, and radiative heat transfer mechanisms, highlighting their potential for efficient, targeted thermal management, and future prospects.

Mode Interference Effect in Optical Emission of Quantum Dots in Photonic Crystal Cavities

Physical Review X, 2022
Radiation properties of a pointlike source of light, such as a molecule or a semiconductor quantum dot, can be tailored by modifying its photonic environment. This phenomenon lies at the core of cavity quantum electrodynamics (CQED).

Narrow Linewidth Spontaneous and Lasing Emissions from Open‐Access Microcavity‐Embedded Perovskite Quantum Dots

Advanced Optical Materials, Volume 14, Issue 1, 9 January 2026.
Continuous‐wave lasing from a small number of perovskite quantum dots is achieved by coupling their photoluminescence to open‐access curved dielectric cavities. This geometry confines their emission into a single optical mode, sharply narrowing linewidths in both spontaneous and lasing regimes.

Entanglement and quantum discord in the cavity QED models

Heliyon
We investigate the quantum correlation between light and matter in bipartite quantum systems, drawing on the Jaynes–Cummings model and the Tavis–Cummings model, which are well-established in cavity quantum electrodynamics.
