High Energy Physics Research

The central objective of all particle physics research is to understand the fundamental interactions of the basic forms of matter and their ultimate structure. The high energy theory group's activity centers on a quantum-field-theoretical study of these interactions, with specific emphasis on gauge field theories, which are indispensable for the description of all interactions.

My research work is in the areas of Theoretical and Mathematical Physics, High Energy Physics and Elementary Particle Physics. Some of the topics of research interest to me include Solitons (Skyrmions), Anomalies in gauge theories, Twistors and scattering amplitudes, Chern-Simons theories, Field theories at finite temperature, Nonperturbative aspects of gauge theories (particularly in 2+1 dimensions), Noncommutative geometry and gravity, Group theoretic approach to fluid dynamics, Quantum Hall systems, Casimir effect.

The Standard Model relies on a single Higgs to give masses to all particles. The large spectrum of masses is attributed to families of 3 x 3 complex Yukawa coupling matrices. What if the Higgs is not a solitary field, but belongs to a bigger family? We enrich the SM by reducing the Yukawa coupling matrices to a single Yukawa coupling constant, and enrich the SM with a family of Higgs fields. Also of recent interest is the Quantum Nature of the Vacuum. What if the vacuum is itself a crystalline solid , with each point in space carrying a half-integer spin. The solid is an eigenstate with vanishing energy-momentum, i.e., the solid is translational invariant. The resulting theory is an emergent field theory of particle physics.
