Article Synopsis
- Retinal degenerative diseases are a major cause of blindness with no current treatments, but retinal prostheses aim to restore vision by activating remaining retinal cells.
- A new photoacoustic retinal stimulation technology was developed using a flexible film that converts near-infrared laser pulses into localized acoustic waves, effectively targeting retinal cells with high precision.
- Testing showed that this method can activate retinal ganglion cells in both normal and degenerated retinae, and the film was safe for use in living rats, suggesting its potential for restoring vision in blind patients with high spatial accuracy.
Quantum Rabi Oscillations in Coherent and in Mesoscopic Cat Field States.
Phys Rev Lett
October 2019
The simple resonant Rabi oscillation of a two-level system in a single-mode coherent field reveals complex features at the mesoscopic scale, with oscillation collapses and revivals. Using slow circular Rydberg atoms interacting with a superconducting microwave cavity, we explore this phenomenon in an unprecedented range of interaction times and photon numbers. We demonstrate the efficient production of cat states, which are the quantum superposition of coherent components with nearly opposite phases and sizes in the range of few tens of photons.

It is induced by a radio frequency field with a high-purity σ^{+} polarization resonant on Stark transitions inside the hydrogenic Rydberg manifold. We observe over a few microseconds more than 20 coherent Rabi oscillations between the initial Rydberg state and the circular level.

Case Presentation: We report a case of serious anaphylactic reaction occurring after a first intraoperative injection of thymoglobulin during renal transplantation in a patient with undiagnosed respiratory allergy to rabbit allergens.
