Laser &Photonics Reviews, EarlyView.A hybrid semiconductor–dielectric microcavity is demonstrated with embedded InGaAs quantum dots, enabling stable continuous‐wave lasing at room‐temperature. Outperforming thermally limited micropillars, the quasi‐planar design supports elevated‐temperature operation, validated through advanced quantum optical characterization, and offers a scalable ...

Time-Dependent Effective Hamiltonians for Light–Matter Interactions
EntropyIn this paper, we present a systematic approach to building useful time-dependent effective Hamiltonians in molecular quantum electrodynamics. The method is based on considering part of the system as an open quantum system and choosing a convenient ...

Experimentally simulating the dynamics of quantum light and matter at deep-strong coupling
Nature Communications, 2017 Realising deep-strong coupling phenomena for interacting light-matter systems remains an experimental challenge. Here, Langford et al. employ a circuit quantum electrodynamics chip with moderate coupling between a resonator and transmon qubit to realise ...

The relation between classical and quantum electrodynamics [PDF]
, 2008 In this article it is presented the idea that quantum electrodynamics presents intrinsic limitations in the description of physical processes that makes it impossible to recover from it the type of description we have with classical electrodynamics.

Global and microlocal aspects of Dirac operators: Propagators and Hadamard states
Mathematische Nachrichten, EarlyView.Abstract We propose a geometric approach to construct the Cauchy evolution operator for the Lorentzian Dirac operator on Cauchy‐compact globally hyperbolic 4‐manifolds. We realize the Cauchy evolution operator as the sum of two invariantly defined oscillatory integrals—the positive and negative Dirac propagators—global in space and in time, with ...

Interaction Induced Quantum Valley Hall Effect in Graphene
Physical Review X, 2015 We use pseudo-quantum electrodynamics in order to describe the full electromagnetic interaction of the p electrons in graphene in a consistent 2D formulation.

To B or not to B: primordial magnetic fields from Weyl anomaly
Journal of High Energy Physics, 2018 The quantum effective action for the electromagnetic field in an expanding universe has an anomalous dependence on the scale factor of the metric arising from virtual charged particles in the loops.

The renormalization of charge and temporality in quantum electrodynamics [PDF]
, 2008 In this article it is intended a closer look at the renormalization procedure used in quantum electrodynamics to cope with the divergent integrals that appear in higher-order calculations within the theory.

The Chemical Record, EarlyView.In February through April 1965, Hoffmann devised several MO tools to explain the regiochemistry of the Diels‐Alder and the preference of the Cope reaction to proceed by the chair rather than boat orientations, when both were possible. The secret lay in secondary orbital interactions that were revealed through qualitative perturbation theory.

Quantum electrodynamics for vector mesons
, 2005 Quantum electrodynamics for $\rho$ mesons is considered. It is shown that, at tree level, the value of the gyromagnetic ratio of the $\rho^+$ is fixed to 2 in a self-consistent effective quantum field theory.
