Anthony Kent (Nottingham) background is in low temperature physics. His Ph.D. was on 2D helium studied by NMR. He came to Nottingham nearly 38 years studying phonons in low dimensional structures, starting optical measurements at low temperatures. During the past 20 or so years he has been studying optomechanical effects at 100s of GHz to 1 THz including THz acoustic cavities and saser (sound amplification by stimulated emission of radiation). Relevant experimental techniques include ultra-fast pump-probe at low temperatures.
