My present research focuses on open quantum systems and non-Hermitian dynamics, with a particular emphasis on how dissipation and non-Hermiticity can be engineered as functional resources in quantum technologies. I develop analytical frameworks to understand light-matter platforms where non-Hermiticity emerges naturally from the system-reservoir interactions, spanning cavity optomechanics and atomic superflows in cavities.
During my PhD, I built the foundations for this program by studying dissipative quantum systems, particularly quantum oscillators strongly coupled to passive reservoirs beyond the Born-Markov-based weak-coupling regime paradigm. In parallel, I worked on the quasi-Hermitian formulation of non-Hermitian quantum mechanics, emphasizing on metric-operator structure, open-system interpretation, and entanglement-entropy-based signatures of non-Hermitian phase transitions.
My current postdoctoral research hinges on developing theoretical frameworks for understanding light-matter interactions along with environmental effects. Concretely, I have been focusing on two related settings, namely, conventional cavity optomechanics and ring-trapped Bose-Einstein condensates (BECs) in cavities, which are formally connected through a common light-matter description and the latter setting amalgamates superfluid and optomechanical behavior. By integrating tools from quantum optomechanics, open quantum systems, and non-Hermitian physics, I study how dissipation and non-Hermiticity lead to 'exceptional behavior', sensing protocols, heat engines, and quantum memories.
In the past, I have worked on various aspects of theoretical and mathematical physics, including geometric mechanics, black hole thermodynamics, classical and quantum exactly-solvable models.
