Spectral Control of an X-Ray L-Edge Transition via a Thin-Film Cavity.

Summary of "Spectral Control of an X-Ray L-Edge Transition via a Thin-Film Cavity."

By embedding a thin layer of tantalum in an x-ray cavity, we observe a change in the spectral characteristics of an inner-shell transition of the metal. The interaction between the cavity mode vacuum and the L_{III}-edge transition is enhanced, permitting the observation of the collective Lamb shift, superradiance, and a Fano-like cavity-resonance interference effect. This experiment demonstrates the feasibility of cavity quantum electrodynamics with electronic resonances in the x-ray range with applications to manipulating and probing the electronic structure of condensed matter with high-resolution x-ray spectroscopy in an x-ray cavity setting.

Nonlinear Control of Electromagnetic Topological Edge States.

Topological photonics has emerged recently as a smart approach for realizing robust optical circuitry, and the study of nonlinear effects is expected to open the door for tunability of photonic topolo...

Bright Mid-Infrared Photoluminescence from Thin-Film Black Phosphorus.

Recently rediscovered layered black phosphorus (BP) provides rich opportunities for the investigations of device physics and applications. The bandgap of BP is widely tunable by its layer number and a...

Cavity Formation in Confined Growing Crystals.

Growing crystals form a cavity when placed against a wall. The birth of the cavity is observed both by optical microscopy of sodium chlorate crystals (NaClO_{3}) growing in the vicinity of a glass sur...

NO2 gas sensing performance enhancement based on reduced graphene oxide decorated V2O5 thin film.

Here, we demonstrate the improved NO2 gas sensing properties based on reduced graphene oxide (rGO) decorated V2O5 thin film. Excluding the DC sputtered grown V2O5 thin film, rGO was spread over V2O5 t...

Medical and Biotech [MESH] Definitions

The thin serous membrane enveloping the lungs (LUNG) and lining the THORACIC CAVITY. Pleura consist of two layers, the inner visceral pleura lying next to the pulmonary parenchyma and the outer parietal pleura. Between the two layers is the PLEURAL CAVITY which contains a thin film of liquid.

Use of a device (film badge) for measuring exposure of individuals to radiation. It is usually made of metal, plastic, or paper and loaded with one or more pieces of x-ray film.

An inner coating, as of varnish or other protective substance, to cover the dental cavity wall. It is usually a resinous film-forming agent dissolved in a volatile solvent, or a suspension of calcium hydroxide in a solution of a synthetic resin. The lining seals the dentinal tubules and protects the pulp before a restoration is inserted. (Jablonski, Illustrated Dictionary of Dentistry, 1982)

A film base coated with an emulsion designed for use with x-rays.

The measurement of radiation by photography, as in x-ray film and film badge, by Geiger-Mueller tube, and by SCINTILLATION COUNTING.
