Cavity Quantum Electrodynamics with Frequency-Dependent Reflectors. [PDF]

Physical Review Letters, 2019
We present a general framework for cavity quantum electrodynamics with strongly frequency-dependent mirrors. The method is applicable to a variety of reflectors exhibiting sharp internal resonances as can be realized, for example, with photonic-crystal ...

Hundreds of Nanocoulomb Electron Acceleration Driven by Multipetawatt Laser in Subcritical Density Plasmas

Advanced Photonics Research, EarlyView.
Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...

Cavity quantum electrodynamics for superconducting electrical circuits: An architecture for quantum computation [PDF]

, 2004
We propose a realizable architecture using one-dimensional transmission line resonators to reach the strong-coupling limit of cavity quantum electrodynamics in superconducting electrical circuits.

Non‐Hermitian Topological Lattice Photonics: An Analytic Perspective

Advanced Photonics Research, EarlyView.
This review establishes exact analytical solutions for non‐Hermitian Hatano–Nelson, Su–Schrieffer–Heeger, and generalized Rice–Mele models. We demonstrate non‐Hermitian skin effects via point‐gap topology, hybrid skin‐topological edge states in 2D lattices, and spin‐polarized boundary modes governed by dual bulk‐boundary correspondence.

Quantum electrodynamical formulation of photochemical acid generation and its implications on optical lithography

ETRI Journal
The photochemical acid generation is refined from the first principles of quan-tum electrodynamics. First, we briefly review the formulation of the quantum theory of light based on the quantum electrodynamics framework to establish the probability of ...

Artificial Intelligence‐Assisted Target Design for High‐Intensity Laser‐Driven Neutron Sources

Advanced Intelligent Systems, EarlyView.
This study presents an artificial intelligence (AI)‐assisted target design that combines particle‐in‐cell simulations with gradient ascent algorithm to optimize laser‐driven neutron sources. By enhancing the sheath electric field, the optimized structure increases neutron yield by a factor of 4,000.

Cosmology Due to Thermodynamics of Apparent Horizon

Annalen der Physik, EarlyView.
Effective cosmological constant as a function of the Hubble rate H for different entropy parameters b. Figure shows the asymptotic of the effective cosmological constant. At H = 0 the effective cosmological constant vanishes. Abstract This study proposes new entropy of the apparent horizon Sh=(1/β)arctan(βSBH)$S_h=(1/\beta)\arctan (\beta S_{BH ...

A Physically-Motivated Quantisation of the Electromagnetic Field on Curved Spacetimes

Entropy, 2019
Recently, Bennett et al. (Eur. J. Phys. 37:014001, 2016) presented a physically-motivated and explicitly gauge-independent scheme for the quantisation of the electromagnetic field in flat Minkowski space.

Quantum Jumps in Amplitude Bistability: Tracking a Coherent and Invertible State Localization

Annalen der Physik, EarlyView.
A notable asymmetry is shown to characterize the bistable switching between macroscopic metastable states of light in the strong‐coupling limit of radiation–matter interaction. Transitions from the vacuum to a highly excited state correlate with a highly bunched sequence of emitted photons, while a downward switch to the vacuum involves a coherent ...

Resurgence in the scalar quantum electrodynamics Euler–Heisenberg Lagrangian

European Physical Journal C: Particles and Fields
We explore the ideas of resurgence and Padé–Borel resummation in the Euler–Heisenberg Lagrangian of scalar quantum electrodynamics, which has remained largely unexamined in these contexts.
