Gauge-independent emission spectra and quantum correlations in the ultrastrong coupling regime of open system cavity-QED

open access: yesNanophotonics, 2022
A quantum dipole interacting with an optical cavity is one of the key models in cavity quantum electrodynamics (cavity-QED). To treat this system theoretically, the typical approach is to truncate the dipole to two levels. However, it has been shown that

Resolving ambiguities of the mode truncation in cavity quantum electrodynamics.

open access: yesOptics Letters, 2022
This work provides the fundamental theoretical framework for few-mode cavity quantum electrodynamics by resolving the gauge ambiguities between the Coulomb gauge and the dipole gauge Hamiltonians under the photonic mode truncation.

Cavity Quantum Electrodynamics with Second‐Order Topological Corner State [PDF]

open access: yesLaser & Photonics reviews, 2020
Topological photonics provides a new paradigm in studying cavity quantum electrodynamics with robustness to disorder. In this work, the coupling between single quantum dots and the second‐order topological corner state are demonstrated.

Kerr-Nonlinearity-Triggered Nonclassicality of Magnons in a Photon-Magnon Coupling System

open access: yesPhotonics, 2022
Hybrid quantum systems have attracted much attention due to the fact that they combine the advantages of different physical subsystems. Cavity QED (cavity quantum electrodynamics) with magnons is a hybrid quantum systems that combines a YIG (Yttrium Iron

Time-resolved physical spectrum in cavity quantum electrodynamics

open access: yesPhysical Review Research, 2022
The time-resolved physical spectrum of luminescence is theoretically studied for a standard cavity quantum electrodynamics system. In contrast to the power spectrum for the steady state, the correlation functions up to the present time are crucial for ...

Cavity quantum electrodynamics with color centers in diamond [PDF]

open access: yes, 2020
Coherent interfaces between optical photons and long-lived matter qubits form a key resource for a broad range of quantum technologies. Cavity quantum electrodynamics (cQED) offers a route to achieve such an interface by enhancing interactions between ...

Resolution of Gauge Ambiguities in Molecular Cavity Quantum Electrodynamics. [PDF]

open access: yesPhysical Review Letters, 2020
This work provides the fundamental theoretical framework for molecular cavity quantum electrodynamics by resolving the gauge ambiguities between the Coulomb gauge and the dipole gauge Hamiltonians under the electronic state truncation. We conjecture that

Nonperturbative cavity quantum electrodynamics: is the Jaynes-Cummings model still relevant? [PDF]

open access: yesJournal of the Optical Society of America B
In this tutorial review, we briefly discuss the role that the Jaynes-Cummings model occupies in present-day research in cavity quantum electrodynamics with a particular focus on the so-called ultrastrong coupling regime.

Polaritonics: from microcavities to sub-wavelength confinement

open access: yesNanophotonics, 2019
Following the initial success of cavity quantum electrodynamics in atomic systems, strong coupling between light and matter excitations is now achieved in several solid-state set-ups.

Coupled Cluster Theory for Molecular Polaritons: Changing Ground and Excited States

open access: yesPhysical Review X, 2020
We present an ab initio correlated approach to study molecules that interact strongly with quantum fields in an optical cavity. Quantum electrodynamics coupled cluster theory provides a nonperturbative description of cavity-induced effects in ground and ...
