Work Experience

A study of AdS Black Holes and Branes (MS project)

  27/07/2020-current      Dr. Rajesh Nayak, IISER Kolkata

I have taken up this project as my Master’s thesis. I will be studying AdS Black Holes and Black Branes.

Independent study on Magnetohydodynamics and Fluid Dynamics

  17/08/2020-current      Dr. Dibyendu Nandi, IISER Kolkata

I have taken up this project as an Independent Study project. I am studying about Magnetohydrodynamics from Dr. Arnab Rai Choudhuri’s textbook “The Physics of Fluids and Plasmas: An Introduction for Astrophysicists” .

EMRI surrogate modeling and late time Kerr tails with spinning primary Black Hole using discontinuous Galerkin method

  15/05/2020-current      Dr. Gaurav Khanna and Dr. Scott Field, UMass Dartmouth

This project was supposed to be carried out in the U.S. but due to COVID-19, this project is being carried out remotely. This work has significantly improved my skills in General Relativity, Matlab and Python coding. I studied Teukolsky equation for s=0 and computed the coupled differential equations for m=0. To get the quasinormal modes, I first used a finite difference method in Python and then used Jan Hesthaven's discontinuos galerkin codes in Matlab. The project is currently ongoing and I will upload the report soon.

Finesse (Frequency domain INterfErometer Simulation SoftwarE) Workshop and Hackathon

  17/12/2019-11/03/2020      IUCAA Pune

Finesse is a sophisticated simulation package for modelling optics and laser interferometers. This interferometer modelling software was developed for the design of gravitational wave detectors, but is easy to use for students with simpler lab-based setups as well. It includes advanced features such as higher-order modes, quantum noise and radiation pressure effects.

Reducing the flexing of the arms of LISA - a space based Gravitational Wave detector

  15/05/2019-15/07/2019      Dr. Rajesh Nayak, IISER Kolkata

LISA stands for Laser Interferometer Space Antenna, it will be a spaced based gravitational wave detector with an array of three spacecrafts in heliocentric orbit. I show how a three body system can be used to model the system and reduce the flexing in the arms of LISA over a period of time.

Deriving Geodesic equations for different types of metrics

  08/12/2018-25/12/2018      Dr. Naresh Dadhich, IUCAA Pune

A reading project of paper “Curved Space, curved Time, and curved Space-Time in Schwarzschild geodetic geometry (arxiv:1812.03259) This project was primarily a reading project, I derived and calculated all the geodesic equations for different types of metrics associated with Schwarzschild geometry, considering space and time curvatures separately.

Reading project in Cosmology, General Relativity and Dark Matter

  15/05/2018-15/07/2018      Dr. Subhadip Mitra, IIIT Hyderabad

A reading project in General Relativity, Cosmology and Dark Matter I studied General Relativity and Cosmology following textbooks by Scott Dodelson, Bernard F. Schutz and James Hartle. The report for the project can be found here

Quantum transport in mesoscopic system

  20/05/2017-20/07/2017      Dr. Sourin Das, IISER Kolkata

I primarily simulated quantum and mesoscopic systems in Python using Kwant module of Python. I simulated different types of topological insulators and varied the position of gates in it and show the periodicity in conductance offered. I also simulated Quantum Hall effect as well as 2D electron gas.
