Learning never exhausts the mind. —Leonardo da Vinci



Keeping focused on the big questions, I think really elevates our lives." - Carla Shatz

In this semester (Semester 1, 2021-22),  I am teaching the following courses (i) Statistical Mechanics and (ii) General Theory of Relativity and Cosmology. 

General Theory of Relativity & Cosmology (PHY F415)
Course description

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.

Statistical Mechanics (PHY F312)
Course description

Classical and quantum mechanics describe motion of particles. However, these approaches are successful
only for system of small number of particles. Most realistic systems that we encounter in the real word
involve large number of particles. Statistical mechanics which combines mechanics with statistics tries to
describe the real systems.
