This year’s APS March Meeting in Baltimore was unquestionably a good one. It seemed like everyone showed up. We were happy to be able to give an invited talk on cavity quantum phonodynamics and two theory talks on our work on quantum dot spin-valley relaxation with the Australians and on the theory of proposed many-body phononic systems. Also of note were the two sessions on Quantum Characterization, Verification, and Validation (I, II) and the four(!) on nano/optomechanics (I, II, III, IV).
