Optomechanical sideband cooling of a micromechanical oscillator close to the quantum ground state
quantum ground optomechanical micromechanical oscillator
2010/11/8
Cooling a mesoscopic mechanical oscillator to its quantum ground state is elementary for the preparation and control of low entropy quantum states of large scale objects. Here, we pre-cool a 70-MHz mi...
Resolved-sideband cooling and measurement of a micromechanical oscillator close to the quantum limit
Resolved-sideband cooling measurement micromechanical oscillator quantum limit
2010/4/8
The observation of quantum phenomena in macroscopic mechanical oscillators has been a subject of interest since the inception of quantum mechanics. Prerequisite to this regime are both preparation of ...
Orbital Period Modulation in Chromospherically Active Close Binaries
Orbital Period Modulation Chromospherically Active Close Binaries
2010/4/16
The orbital period changes in some chromospherically active close binaries have been interpreted as a consequence of magnetic activity. At least in two active close binaries a possible relationship be...
