Dr. Kalaivanan Nagarajan research focuses on exploring the fundamental and applied aspects of light–matter strong coupling, particularly vibrational strong coupling (VSC), to understand and manipulate chemical reactivity and material properties within optical cavities. By integrating principles from physical chemistry, quantum electrodynamics, and materials science, the work investigates how molecular vibrations interact coherently with confined optical modes in Fabry–Perot cavities to form hybrid light–matter states known as vibrational polaritons. These studies reveal how strong coupling conditions can reshape potential energy surfaces, influence molecular structure, dynamics, and reaction kinetics, and ultimately enable control of chemical transformations without the need for external photoexcitation. A key highlight of this research is the demonstration that VSC can modulate phase transition behaviors, such as the glass transition temperature of polymers like polyvinyl acetate and polystyrene, providing experimental evidence of cavity-modified thermomechanical properties. Through systematic spectroscopic, thermodynamic, and theoretical investigations, the research establishes how vacuum electromagnetic fields play an active role in determining material behavior and chemical outcomes. This pioneering approach contributes to the emerging field of polariton chemistry, offering new pathways for designing energy-efficient reactions, reactivity control strategies, and material innovations driven by quantum light–matter interactions.
