Nonreciprocity and modulation in optomechanics (Dr. Daniel Malz)

In quantum technologies, they serve to protect sensitive quantum systems from excess noise. Conventionally, they rely on on the Faraday effect in ferrite materials and require large magnetic fields. There is large interest in magnetic-field-free alternatives integrable on superconducting chips. I will present recent advances to make such devices with optomechanics, discuss the underlying mechanism for directionality, and show how it is generalised to arbitrary systems, especially fermionic ones.
