Semester I, 2025-26: List of student project problems will be uploaded soon. Interested students can fill the google form (to be made available here). He/she needs to attach his/her one page CV(that should contain the list of course that he/she has completed/registered till now, his/her programming efficiency, CGPA, etc.) in the form.
In this semester (Semester II, 2024-25), I am teaching the following two courses: (i) Particle Physics and (ii) General Theory of Relativity(GTR) and Cosmology.
This course aims to introduce the basic concepts of Particle Physics. The main objective is to know how the fundamental particles (e.g. electron, muon, quarks, photon, gluon etc) interact with each other at high energy. After reviewing basic concepts of special relativity (in 4 vector formalism), non- relativistic and relativistic quantum mechanics, the free-particle relativistic wave equations i.e. Klein-Gordan equation (spin-0 particle - pion), Dirac equation(spin-1/2 particle - electron), Maxwell equation(spin-1 article - photon) will be derived. The role of symmetry and conservation laws in Particle Physics will be discussed at a length. A brief overview of group(Lie) theory will be given. The gauge theory of electron-photon interaction(Quantum Electrodynamics(QED)) will be developed and a brief introduction of electron-proton(e-p) deep-inelastic scattering will be given. Few QED processes e.g. the muon pair production in electron-positron annihilation, Bhabha scattering, and decay of neutral Z and Higgs(H) boson will be discussed at a length.

This course aims to introduce the basic concepts of General Theory of Relativity and it's application in Cosmology i.e. to know the behavior of the universe at large scale. After reviewing basic concepts of special relativity (in 4 vector formalism), the notion of tensor, covariant derivative, geodesics, curvature tensor, Ricci tensor, Ricci scalar, Einstein tensor and hence the Einstein equations will be derived. The Schwarzschild black hole solution of the Einstein equation will be discussed, which will be followed by Physics near the massive objects. The FRW cosmology will be discussed at a length and finally inflationary cosmology will be introduced in brief.
