Chiral symmetries associated with angular momentum
M. Bhattacharya, M. Kleinert
In beginning quantum mechanics courses, symmetries of a physical system are usually introduced as operators which commute with the Hamiltonian. In this article we will consider chi…
Mechanical memory for photons with orbital angular momentum
H. Shi, M. Bhattacharya
We propose to use an acoustic surface wave as a memory for a photon carrying orbital angular momentum. We clarify the physical mechanism that enables the transfer of information, d…
Ray transfer matrix for a spiral phase plate
M. Eggleston, T. Godat, E. Munro +3
We present a ray transfer matrix for a spiral phase plate. Using this matrix, we determine the stability of an optical resonator made of two spiral phase plates, and trace stable r…
Quantum mechanical study of a generic quadratically coupled optomechanical system
H. Shi, M. Bhattacharya
Typical optomechanical systems involving optical cavities and mechanical oscillators rely on a coupling that varies linearly with the oscillator displacement. However, recently a c…
Coupling a small torsional oscillator to large optical angular momentum
H. Shi, M. Bhattacharya
We propose a new configuration for realizing torsional optomechanics: an optically trapped windmill-shaped dielectric interacting with Laguerre-Gaussian cavity modes containing bot…
