'LIGHT, SOUND and TOPOLOGY'

Abstract:
The interaction between radiation and mechanical motion on the nanoscale 
is now
being studied intensively. Known as cavity optomechanics, this field 
promises applications
in quantum communication, sensitive measurements, and fundamental 
studies of quantum
physics. After a general introduction, I will turn to some recent ideas 
of ours that envisage
controllable transport of photons and phonons in so-called 
optomechanical arrays. Once
realized, these systems could feature engineered chiral edge channels 
for light and sound
that are topologically protected against disorder- scattering.
