Two coupled Jaynes-Cummings cells
, 2012 We develop a theoretical framework to evaluate the energy spectrum, stationary states, and dielectric susceptibility of two Jaynes-Cummings systems coupled together by the overlap of their respective longitudinal field modes, and we solve and ...

Quantum Jumps in Amplitude Bistability: Tracking a Coherent and Invertible State Localization
Annalen der Physik, Volume 538, Issue 1, January 2026.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 ...

Physical Review ResearchDecoherence of a charge qubit is usually credited to charge noise in the environment. Here we show that charge noise may not be the limiting factor for the qubit coherence.

Excited States of Coherent Harmonic Qubits With Long‐Range Photon Coupling and Dissipation
Annalen der Physik, Volume 537, Issue 12, December 2025.When N qubits are strongly coupled with photons in a cavity, they can condense into a ground state with negative energy gap. Some new information is found on coherent transitions among excited states of this system, by simulating them numerically for small N.

Multielectron Ground State Electroluminescence
, 2019 The ground state of a cavity-electron system in the ultrastrong coupling regime is characterized by the presence of virtual photons. If an electric current flows through this system, the modulation of the light-matter coupling induced by this non ...

Nanophotonics, Volume 14, Issue 23, Page 3723-3760, 02 November 2025.Abstract Polaritons are quantum mechanical superpositions of photon states with elementary excitations in molecules and solids. The light–matter admixture causes a characteristic frequency‐momentum dispersion shared by all polaritons irrespective of the microscopic nature of material excitations that could entail charge, spin, lattice or orbital ...

Analytical Solutions of the Driven Time‐Dependent Jaynes–Cummings Model
Annalen der Physik, Volume 537, Issue 10, October 2025.Following the great strides made in the last decade towards the control and tunability of physical parameters in cavity quantum electrodynamics, this study presents new solutions to the dynamics of the time‐dependent Jaynes–Cummings model with variable external classical fields acting on the two‐level system and the quantized field mode.

Collective effects in the collapse-revival phenomenon and squeezing in the Dicke model
, 1998 Resonant interaction of a collection of two-level atoms with a single-mode coherent cavity field is considered in the framework of the Dicke model. We focus on the role of collective atomic effects in the phenomenon of collapses and revivals of the Rabi ...

Low‐dimensional solid‐state single‐photon emitters
Nanophotonics, Volume 14, Issue 11, Page 1687-1713, June 2025.Abstract Solid‐state single‐photon emitters (SPEs) are attracting significant attention as fundamental components in quantum computing, communication, and sensing. Low‐dimensional materials‐based SPEs (LD‐SPEs) have drawn particular interest due to their high photon extraction efficiency, ease of integration with photonic circuits, and strong coupling ...
