From cavity to cavityless optomechanics: Phonon cooling, bistability and lasing

Dr. Mishkat Bhattacharya, Rochester Institute of Technology

Goergen Hall, Room 101

In this talk I will first briefly review the field of cavity optomechanics, i.e. the interaction of mechanical oscillators with electromagnetic modes. Subsequently, I will describe cavityless levitated optomechanics. Theoretical activity on the topic will be reported from our group at RIT, in the context of ongoing experiments in various groups, especially that of A. N. Vamivakas at the Institute of Optics, University of Rochester. Topics such as cooling, force sensing, bistability and phonon lasing will be considered.


Mishkat Bhattacharya obtained his PhD in Physics from the University of Rochester in 2005, and held postdoctoral positions at Georgia Tech, the University of Arizona and the University of Maryland at College Park, before joining the Rochester Institute of Technology as an Assistant Professor in 2011.
