Trapping and cooling single atoms with far-off resonance intracavity doughnut modes [PDF]

, 2002
We investigate cooling and trapping of single atoms inside an optical cavity using a quasi-resonant field and a far-off resonant mode of the Laguerre-Gauss type. The far-off resonant doughnut mode provides an efficient trapping in the case when it shifts

Quantum quincunx in cavity quantum electrodynamics [PDF]

Physical Review A, 2003
We introduce the quantum quincunx, which physically demonstrates the quantum walk and is analogous to Galton's quincunx for demonstrating the random walk. In contradistinction to the theoretical studies of quantum walks over orthogonal lattice states, we introduce quantum walks over nonorthogonal lattice states (specifically, coherent states on a ...

Quantum Computation with Quantum Dots and Terahertz Cavity Quantum Electrodynamics [PDF]

, 1999
A quantum computer is proposed in which information is stored in the two lowest electronic states of doped quantum dots (QDs). Many QDs are located in a microcavity. A pair of gates controls the energy levels in each QD. A Controlled Not (CNOT) operation

Double Helical Plasmonic Antennas

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Emerging Device Applications From Strong Light–Matter Interactions in 2D Materials

Advanced Science, Volume 13, Issue 17, 23 March 2026.
Two‐dimensional semiconductors enable extremely compact optoelectronic devices such as solar cells, sensors, LEDs, and lasers. Their strong light–matter interactions allow efficient light emission, detection, and energy conversion. This review article discusses the recent progress in integrating these materials with optical cavities and nanostructures ...

Coupling Enhancement and Symmetrization in Dissipative Optomechanical Systems

Annalen der Physik, Volume 538, Issue 3, March 2026.
A practical circuit‐QED scheme with dual coherent laser driving and enhanced cross‐Kerr nonlinearity is presented to achieve ultrastrong optomechanical coupling in the few‐photon regime. A symmetric optomechanical dynamical framework is further established to enable a systematic classification of different coupling regimes.

All Optical Switch of Vacuum Rabi Oscillations: The Ultrafast Quantum Eraser

, 2010
We study the all-optical time-control of the strong coupling between a single cascade three-level quantum emitter and a microcavity. We find that only specific arrival-times of the control pulses succeed in switching-off the Rabi oscillations.

Deterministic cavity quantum electrodynamics with trapped ions [PDF]

, 2003
We have employed radio-frequency trapping to localize a single 40Ca+-ion in a high-finesse optical cavity. By means of laser Doppler cooling, the position spread of the ion's wavefunction along the cavity axis was reduced to 42 nm, a fraction of the ...
