New Spectroscopy Methods :: Quantum Dynamics & Exciton Physics :: Theory & Computational Spectroscopy
who we are
We are an interdisciplinary group of physicists and physical chemists who work at the interface of experiment and theory.
We are broadly interested in how exciton physics manifests in materials and molecular assemblies from the perspective of quantum dynamics.
We like playing with ultrafast optical components, electronics and femtosecond laser pulses in a dark optics lab. We also like to play with toy model Hamiltonians on a computer to understand our experiments through analytic theory and computation. Alongside answering fundamental questions, we also leverage our expertise in optics and electronics to invent applied optical devices for sensing and imaging applications.
questions that excite us
What fundamental photophysics make a material functional ? For example, what determines quantum transport in dissipative systems ?
Our group develops advanced optical spectroscopy techniques and quantum dynamical models to probe a variety of questions in condensed matter physics and chemistry, which ultimately determine material functionality. Such questions include - how does an exciton transport in a lattice, how does it dissociate to yield charge carriers, and why is this yield efficient in certain materials versus poor in others? Can we learn quantum transport principles from natural photosynthesis ? Can natural photosynthesis guide the design of new photovoltaics with improved charge generation, etc. ?
Visit our publications page to learn more about such questions and our recent insights, and our current systems of interest.
research theme
Discovering new phenomenon to refine existing theoretical models necessarily requires inventing experiments that surpass the state-of-the-art
We strive to gain a fundamental understanding of the electronic properties of materials from a quantum dynamical perspective. Emerging light harvesting and electronics technologies depend on functional materials such as organic semiconductors, inorganic perovskites, and layered 2D materials. Femtosecond timescales are the natural scales to probe the initial steps of electronic relaxation in these systems that eventually governs the performance of these technologies.
Typically all projects in our group involve both, experimental and theoretical components. Visit our research page or directly contact us to know more about our current research directions.
