Prospect of Studying Nonperturbative QED with Beam-Beam Collisions.

Published: May 2019

We demonstrate the experimental feasibility of probing the fully nonperturbative regime of quantum electrodynamics with a 100 GeV-class particle collider. By using tightly compressed and focused electron beams, beamstrahlung radiation losses can be mitigated, allowing the particles to experience extreme electromagnetic fields. Three-dimensional particle-in-cell simulations confirm the viability of this approach. The experimental forefront envisaged has the potential to establish a novel research field and to stimulate the development of a new theoretical methodology for this yet unexplored regime of strong-field quantum electrodynamics.

Quantum Dynamics Simulations of Exciton Polariton Transport.

Nano Lett

Department of Chemistry, University of Rochester, Rochester, New York 14627, United States.

Recent experiments have shown that exciton transport can be significantly enhanced through hybridization with confined photonic modes in a cavity. The light-matter hybridization generates exciton-polariton (EP) bands, whose group velocity is significantly larger than the excitons. Dissipative mechanisms that affect the constituent states of EPs, such as exciton-phonon coupling and cavity loss, have been observed to reduce the group velocities in experiments.

Phaseless Auxiliary-Field Quantum Monte Carlo Method for Cavity-QED Matter Systems.

J Chem Theory Comput

Center for Computational Quantum Physics, The Flatiron Institute, 162 Fifth Avenue, New York, New York, 10010, United States.

We present a generalization of the phaseless auxiliary-field quantum Monte Carlo (AFQMC) method to cavity quantum-electrodynamical (QED) matter systems. The method can be formulated in both the Coulomb and the dipole gauge. We verify its accuracy by benchmarking calculations on a set of small molecules against full configuration interaction and state-of-the-art QED coupled cluster (QED-CCSD) calculations.

Entanglement and quantum discord in the cavity QED models.

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. Through the resolution of the quantum master equation, we can derive the dissipative dynamics in open systems. To assess the extent of quantum correlation, several measures are introduced: von Neumann entropy, concurrence and quantum discord.

Enhanced Light-Matter Interaction with Bloch Surface Wave Modulated Plasmonic Nanocavities.

Article Synopsis
  • Strong coupling between nanocavities and single excitons at room temperature is crucial for studying cavity quantum electrodynamics, influenced by factors like light confinement and electric field orientation.
  • A hybrid cavity design combining a one-dimensional photonic crystal and plasmonic nanocavity enhances quality factor, minimizes mode volume, and allows control of electric field direction using Bloch surface waves.
  • Achieving a Rabi splitting of around 186 meV with only 8 excitons involved marks a significant advance, producing an effective coupling strength of 17.6 meV per exciton, which is nearly double the previously reported values for TMD-based systems.
