Progress towards measuring the standard quantum limit using a monolithic sapphire transducer

The operation of a novel monolithic sapphire transducer (MST) that has low mechanical and electrical losses is presented. The MST senses the motion of internal acoustic resonances through the interaction between electric and acoustic fields. Progress towards measuring the standard quantum limit by i...

Zusammenfassung:The operation of a novel monolithic sapphire transducer (MST) that has low mechanical and electrical losses is presented. The MST senses the motion of internal acoustic resonances through the interaction between electric and acoustic fields. Progress towards measuring the standard quantum limit by implementing a cryogenic MST is described.
