Study of equilibrium properties of Aditya-U Tokamak and DIII-D Tokamak

A python based interface is written, to initially read the EFIT file from Aditya-U, and visualize the limiter boundaries, last closed magnetic flux surface. Magnetic Flux surfaces are generated using Euler-Method of integration which is eventually used for simulation grids construction on top of the flux surface contours in a chosen poloidal plane.

Molecular Dynamics Simulation of a coarse-grained linear polymer chain model under varying conditions; and estimation of the θ-solvent of the model

Polymers are collections of monomers, each made up of atoms and molecules, displaying complex properties when in a solvent. A key property is when a polymer behaves like an ideal chain, leading to the concept of a θ-solvent, where simulations of coarse-grained linear polymer chains help estimate this behavior under various conditions.

Review on the dynamics and coil-globule phase transition of single-stranded polymers in two dimensions

Research on polymers, which began in the 19th century, underscores their significance in daily materials. Understanding polymer dynamics is essential due to its extensive applications in science and technology. This study explores both theoretical and experimental perspectives, focusing on Brownian motion, ideal chain dynamics, and temperature-induced coil-globule transitions. The final chapter provides a summary of the key findings.

A Conformal Treatment of Minkowski and Schwarzschild Spacetime

A brief introduction to physical spacetimes such as Minkowski and Schwarzschild is presented initially. This is followed by a conformal mapping of these spacetimes to explore their asymptotic properties. Lastly, the resulting compact structure from the mapping is discussed.
