• Abstract summary: We report on measurements of photon induced heating of silica nanospheres levitated in vacuum by a thermal light source formed by a superluminescent diode. We find the measured trap heating rates are dominated by the much larger heating rates expected from the recoil of thermal photons.

• Abstract: We report on measurements of photon induced heating of silica nanospheres levitated in vacuum by a thermal light source formed by a superluminescent diode. Heating of the nanospheres motion along the three trap axes was measured as a function of gas pressure and for two particle sizes. Heating rates were also compared with the much lower reheating of the same sphere when levitated by a laser. We find the measured trap heating rates are dominated by the much larger heating rates expected from the recoil of thermal photons.

  We present the master equation describing the impact of heat radiation on the motional quantum state of arbitrarily sized and shaped rigid rotors. A counter-intuitive implication is that orientational superpositions of optically isotropic bodies are not protected by their symmetry, even in the small-particle limit.

  We experimentally demonstrate how to generate a state in condensed matter at moderate cryogenic temperatures. This state is then used to efficiently remove microwave photons from a cavity. Such an "anti-maser" device could be extremely beneficial for applications that would normally require cooling to millikelvin temperatures.

• Realising Einstein's mirror: Optomechanical damping with a thermal photon gas [0.0]
  In 1909 Einstein described the thermalization of a mirror within a blackbody cavity by collisions with thermal photons. We show that the time to thermalize the motion of even a microscale or nanoscale object is so long that it is not feasible. We predict damping of the center-of mass motion due to this effect on times amplified scales of seconds for small optomechanical systems.
