Microwave–optical conversion is key to future networks of quantum devices, such as those based on superconducting technology. Conversion at the single quantum level requires strong nonlinearity, high bandwidth, and compatibility with a millikelvin

We study the ultrastrong driving of Rydberg excitons in Cu _2 O by a microwave field. The effect of the field is studied using optical absorption spectroscopy, and through the observation of sidebands on the transmitted laser light. A model based on

Lactococcus garvieae is a gram-positive cocci that has primarily been described as a pathogen in various fish species, but has increasingly been reported to cause endocarditis and other infections in humans [1]. Neonatal infection caused by Lactococc

We report exciton-mediated coupling between microwave and optical fields in cuprous oxide (Cu_{2}O) at low temperatures. Rydberg excitonic states with principal quantum number up to n=12 were observed at 4 K using both one-photon (absorption) and two

We present a study of even parity Rydberg exciton states in cuprous oxide using time-resolved second harmonic generation (SHG). Excitonic states with principal quantum number n = 5 - 12 were excited by nanosecond pulses around 1143 nm. Using time-res

High-lying Rydberg states of Mott-Wannier excitons are receiving considerable interest due to the possibility of adding long-range interactions to the physics of exciton-polaritons. Here, we study Rydberg excitation in bulk synthetic cuprous oxide gr
