The members of the faculty of the department of physics specialize in topics related to materials science, nanomaterials, coupled nanomaterials, scanning tunneling microscopes, first principle study of 2d magnetic/nonmagnetic materials, nuclear structure and decay, and low energy nuclear astrophysics. The faculty have publications in renowned journals in their respective fields. Presently our department has five faculty members in substantive posts.

The department has a well-equipped laboratory facility for conducting practical classes following the present syllabus.

It has a separate computer laboratory with computers with the latest hardware configurations and operating systems (Windows and Linux), a LaserJet printer and internet connection through Wi-Fi and LAN.
The department also has a gallery classroom which is equipped with a projector and a whiteboard in addition to a traditional blackboard to facilitate a smooth teaching-learning experience.

The dedicated non-teaching support-staff of our department help in the day-to-day conduct of the classes, as also in the conduct of the practical examinations.

From session 2023-24 onwards, we offer 4 Year B.Sc. Physics (Honours & Honours with Research), and 3 Year B.Sc. Multi-Disciplinary Course (MDC) under the Curriculum and Credit Framework (CCF) of the New Education Policy (NEP).
Also, the department runs courses under the Choice Based Credit System (CBCS) Framework introduced by the UGC for Honours and General students. At present, 4th and 6th Semester classes are under the CBCS scheme.
