Bio

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

PHYS-213
3 Credits
This course provides an introductory survey of elementary quantum physics, as well as basic relativistic dynamics. Topics include the photon, wave-particle duality, deBroglie waves, the Bohr model of the atom, the Schrodinger equation and wave mechanics, quantum description of the hydrogen atom, electron spin, and multi-electron atoms.
PHYS-275
1 Credits
This seminar will assist students in their preparation for the Physics Comprehensive Oral Exam (CORE) required at the end of the course by presenting a unified as opposed to topical approach to physics. Physics majors must pass this course before going on to 300-level Physics courses.
PHYS-450
1 Credits
This course is a preparation for the two-semester physics capstone project to be carried out in the following year. It includes selection of a project and faculty mentor, preparation of a feasibility study, preparation of a paper, and a public oral presentation.
PHYS-601
1 Credits
This course is the first in a two-semester sequence intended to familiarize students with research activities, practices, and 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. As part of the course, students are expected to attend research seminars sponsored by the School of Physics and Astronomy and participate in regular journal club offerings. The course also provides training in scientific writing and presentation skills. Credits earned in this course apply to research requirements.
PHYS-452
3 Credits
In collaboration with faculty mentor(s), students will carry out the final phase of an experimental, theoretical, or computational physics research project, will prepare a written paper and present an oral report on their progress to physics faculty and students. The projects are those planned during the capstone preparatory course taken during the prior Spring semester and commenced during the prior Fall semester.
PHYS-451
3 Credits
In collaboration with faculty mentor(s), students will carry out the first phase of an experimental, theoretical, or computational physics research project, will prepare an interim paper, and will present a short talk on their progress to physics faculty and students. The projects are those planned during the capstone preparatory course taken during the prior Spring semester.
