Biography

I am a doctoral researcher in theoretical physics at the University of Turku. I received my master’s degree in theoretical physics from the same institution, where I focused on the optical properties of quantum dots through simulations using hierarchical methods. My PhD research explores phenomena related to polaritonic quantum batteries, such as superabsorption, pump-probe spectroscopy, and transient absorption.

Research

My research focuses on theoretical investigation of polaritonic quantum batteries that leverage the hybrid nature of polaritons for efficient energy storage and transfer. Polaritons are quasi-particles resulting from strong coupling between light and matter. I study the interactions of these polaritons to find new mechanisms for increased energy absorption and emission. Main aspects of my research include exploring superabsorption, a phenomenon where cooperative effects between polaritons enhance the absorption of energy, pump-probe spectroscopy, non-linear effects and transient absorption.
