Abstract
Optomechanical Hamiltonians describe a plethora of different systems
with radiation-pressure-like interactions. Its avatars can be found in
microwave optomechanical circuits, superconducting circuits, and cavity
optomechanics. They all share time dependent non-adiabatic boundary
conditions. I will focus on the traditional set-up where mechanical and
electromagnetic energies are exchanged and I will explore a particular
configuration in which a perfect two-sided movable mirror is put inside a
cavity. A classical Hamiltonian for this system is first derived and then
quantised and I will explore different resonance conditions that lead to
a photon hopping effect not due to tunnelling and a bilateral radiating
process that we called the Janus effect.
