Department of Physics

The Department of Physics started B.Sc. pass course in 1947. The department has faculty with interests ranging from experimental to theoretical aspects of condensed matter physics, optics, spectroscopy, image processing, field theory and quantum computation. The present faculty members are highly dedicated for quality physics education with innovative methods of theory teaching and practices; and inspiring and guiding laboratory classes. The faculty and students in the department are cooperatively contributing towards the advancement of scientific knowledge at the frontiers of human understanding of sciences, in general, and physics in particular. This process essentially intertwines the basic development of scientific temperament in the classroom, laboratory instruction activities within the department in conjunction with the Central Research Laboratory of the college and dissemination through professional channels in the classroom.


The Department of Physics, St. Xavier’s College, Ranchi, will be a national leader in the integration of (i) teaching and learning, (ii) advancement of the knowledge base through research and scholarship, and (iii) leadership in service to mankind and outreach. Further, the Department will be a national leader in preparing young motivated and enlightened individuals who will be providing leadership in creating a working and learning environment that supports research as integral to learning, thinking, and advancing knowledge, within any institution of the world, they associate themselves with.


The Department of Physics is committed to excellence in the education of its undergraduate students in core as well as related areas that encompass understanding of physical concepts, the generation and dissemination of new scientific knowledge involving physical principles and their applications. Its objective is to have a beneficial impact on the society and nation at large, while enhancing the quality of teaching and research.

The mission of the department is to provide student-centered education, with emphases on quality teaching, student-faculty research, scholarly activity, service, and maintaining an active and congenial atmosphere for teaching and learning, in which faculty members set a high priority in teaching and strive to build a caring and learning environment for students.


  • Each and every individual belonging to any section of society is entitled to a high-quality education, grounded in sensitivity to individual dignity, professional integrity, and a positive and nurturing environment.
  • Teaching and learning should be informed by scholarly research and effective practice.
  • Technology should be used to improve the quality of teaching and learning, research and scholarship, and outreach to the state, nation, and the world.
  • An inspired student continues learning throughout life
  • Interdisciplinary programs should be used to enhance human learning, growth, and development across the life span.

Programme Outcomes

The department is very actively involved in teaching and research in areas of Material Science and Nanotechnology. It is equipped with state of art UG labs to cater the needs of students pursuing physics as honors and also to students who have physics as Generic elective subject. UG curriculum, besides the core courses in physics, includes courses like computer programming lab, C/C++ programming which are important for students to grow academically as researchers. Salient features of the programme are listed below

  • The Physics honors course curriculum is designed so as to enable the students develop an advanced theoretical and research skills in fields of contemporary science, and their relevance, from day to day life to current developments in physics.
  • Provide them a platform for higher academic options viz., Master of Science (M Sc)/ Master of Philosophy (M Phil) or Doctor of Philosophy (Ph D)and other professional career.
  • Students pursuing this course are also eligible for other employment opportunities like teaching, research, banking,businessor they can even go for startups etc.The course aims at making graduates successful professionals by demonstrating logical and analytical thinking abilities for solving problems in any sphere they work.
  • The course makes them learn and communicate effectively, either independently or in a team, and demonstrate leadership qualities.
  • Through this program, interested students are provided an opportunity to gain first-hand experience of experimental/theoretical/computational research in different areas, preferably Material Science and Nano-technology, under the supervision of faculty members in the department. This is likely to enhance student’s insight into research work and make him/her compatible for a broad range of career opportunities.

Programme Specific Outcomes

  • Develop ability to choose, analyze and interpret information from variety of sources like books, journals, classroom teaching, open access courseware and the internet.
  • Learn mathematical tools and computational techniques for solving and analyzing complex physical problems.
  • Demonstrate experiments to determine different physical quantities, physical constants and other measurements and to analyze data acquired from those experiments.
  • Critically interpret data using computational and graphical means and write reports of the same.
  • Learn programming languages and apply it to solve various problems related to Quantum mechanics, thermodynamics and other relevant branches of physics.
  • Understand core physical concepts, key principles and theories along with their applications and develop ability to solve complex problems.
  • Familiarize students with current developments in physics and research areas.
  • Learn through participation in multidisciplinary seminars/ workshops as a team and work cooperatively and responsibly as a member of the team.

Course Outcomes
