Observation of a phase transition in KTaO induced by residual niobium impurities
Zijun C. Zhao, Jeremy F. Bourhill, Maxim Goryachev +2
We report the observation of a phase transition in a KTaO crystal, corresponding to a paraelectric-to-ferroelectric transition. The crystal was placed inside a copper cavity to…
Generation of Coherent Phonons via a Cavity Enhanced Photonic Lambda Scheme
Jeremy Bourhill, Natalia do Carmo Carvalho, Maxim Goryachev +2
We demonstrate the generation of coherent phonons in a quartz Bulk Acoustic Wave (BAW) resonator through the photoelastic properties of the crystal, via the coupling to a microwave…
Spin bath maser in a cryogenically cooled sapphire whispering gallery mode resonator
J. Bourhill, K. Benmessai, M. Goryachev +3
We report the observation of a mechanism of maser generation in an ensemble of inter-coupled, inhomogeneously broadened two-level systems, enhanced by high quality factor electroma…
