Superlocalization of Excitons in Carbon Nanotubes at Cryogenic Temperature

At cryogenic temperature and at the single emitter level, the optical properties of single-wall carbon nanotubes depart drastically from that of a one-dimensional (1D) object. In fact, the (usually unintentional) localization of excitons in local…

Coherent microwave-to-optical conversion by three-wave mixing in a room temperature atomic system

We experimentally observe coherent generation of a near-infrared optical field through a three-wave mixing phenomenon in an atomic energy level scheme of 85 Rb atoms. This nonlinear generation process in a centro-symmetric thermally broadened atomic…

Exciton-Exciton Annihilation in Two-dimensional Halide Perovskites at Room Temperature

Recently, Ruddlesden–Popper 2D perovskite (RPP) solar cells and light-emitting diodes (LEDs) have shown promising efficiencies and improved stability in comparison to 3D halide perovskites. Here, the exciton recombination dynamics is investigated at…

Susceptibility to ABO and TBOA of LTD and extrasynaptic NMDAR-dependent tonic current in the aged rat hippocampus

Aging, as the major risk factor of Alzheimer's disease (AD), may increase susceptibility to neurodegenerative diseases through many gradual molecular and biochemical changes. Extracellular glutamate homeostasis and extrasynaptic glutamate N-Methyl-D…

Phase-sensitive amplification of an optical field using microwaves

We report phase-sensitive amplification (PSA) of a near-infrared electromagnetic field using room-temperature 85 Rb atoms possessing ground-state coherence. Our novelty is in achieving significant optical PSA by manipulating the intensity and phase…

Thermal phase fluctuations in optically pumped dual–frequency vertical external-cavity surface-emitting lasers for cesium clocks based on coherent population trapping

A fully analytical model is established for the thermal fluctuations of the beatnote phase of an optically pumped dual-frequency Vertical-External-Cavity Surface-Emitting Laser (VECSEL). This model starts with the resolution of the heat equation…
