Dr. Mishkat Bhattacharya is an Assistant Professor of Physics and Astronomy at the Rochester Institute of Technology. He is a program faculty in the Center for Imaging Sciences at RIT and a member of the Center for Coherence and Quantum Optics at the University of Rochester. Dr. Bhattacharya received the B.Tech degree in Engineering Physics from the Indian Institute of Technology, Bombay, and the Ph.D. degree from the University of Rochester. He held postdoctoral positions at the Georgia Institute of Technology, the University of Arizona, and the University of Maryland, College Park, before joining RIT in 2011. Dr. Bhattacharya teaches freshman mechanics, modern physics, quantum mechanics and quantum optics. He reviews regularly for journals such as Physical Review Letters, the Journal of Physics B, and the American Journal of Physics.

The Bhattacharya group is broadly interested in light-matter interactions from the perspective of fundamental science as well as technological applications. Currently it is focused on the interplay of electromagnetic modes of radiation, such as laser light, with nanofabricated components, such as mechanical oscillators and rotors. Major aims are the cooling of macroscopic objects into the quantum regime and establishing the limits to quantum sensing of mechanical displacement, force, and rotation, for example. These investigations are expected to test the foundation of quantum mechanics as well as to yield next generation sensors that circumvent the limits posed by quantum mechanics to their sensitivity. Some of the group effort also goes towards investigating other related platforms for quantum technologies such as ultracold atoms and molecules. The work is fully theoretical, involving mostly analytical calculations, using the techniques of quantum optics and atomic physics, and some medium-scale numerical work. Close collaborations exist with experimental groups locally, nationally, as well as internationally. The program involves researchers at every level, including undergraduate, masters, and doctoral students as well as postdoctoral scholars. Recent funding sources include the Research Corporation for Science Advancement, the Office of Naval Research, and the National Science Foundation.

Currently Teaching

1 Credits
This course is the second in a two-semester sequence intended to familiarize students with research activities, practices, ethics in university, government, industry, and other professional research environments and to introduce students to research tools and skill sets important in various professional environments. The course is intended to help students develop a broad awareness of current professional and funding opportunities. As part of the course, students are expected to attend research seminars sponsored by the School of Physics and Astronomy, to participate in regular journal club offerings, to engage in outreach activities, and to participate in visits to regional laboratories and companies. The course provides training in proposal writing and presentation skills. Credits earned in this course apply to research requirements.
