Tidal Effects in the Vicinity of Compact Objects

Santanu Pradhan

PhD Research, Department of Physics, IIT Kanpur

Investigating tidal gravitational effects near black holes and neutron stars, focusing on tidal deformability, Love numbers, and their signatures in gravitational wave observations from LIGO-Virgo-KAGRA. This research aims to develop new frameworks for testing strong-field gravity using compact binary mergers.

MSc Thesis

Quasi-Normal Modes of Black Holes

Santanu Pradhan

MSc Thesis, IIT Indore

A comprehensive study of quasi-normal modes (QNMs) for Kerr black holes using a novel computational technique, with detailed comparison against Leaver's continued fraction method. The work explores the QNM spectrum across different spin parameters and multipole moments, analyzing the ringdown phase of black hole perturbations.

Properties of Anti-de Sitter Black Holes

Santanu Pradhan

Academic Project, IIT Indore

A study of black holes in Anti-de Sitter (AdS) spacetime, exploring their thermodynamic properties through the lens of the AdS/CFT correspondence. The report covers black hole thermodynamics, Hawking–Page phase transitions, holographic duality, and connections to condensed matter physics via holographic superconductors.

Unruh Radiation

Santanu Pradhan

Academic Project, IIT Indore

An exploration of the Unruh effect — the theoretical prediction that an accelerating observer in vacuum perceives thermal radiation. The report covers general relativity foundations, quantum field theory in curved spacetime, Rindler coordinates, Bogoliubov transformations, and connections to Hawking radiation and the equivalence principle.
