Research Interests
Our group activities are highly interdisciplinary in nature. We study strong interactions between light (photon) and molecules by placing them in the confined electromagnetic field of a cavity or a plasmonic nanostructure. A molecule exchanges energy between the cavity and the molecular state through Rabi oscillations (resonance interaction), creating two new eigenstates called polaritonic states. At ON-resonance conditions, polaritonic states are half-molecule and half-photon-like; they show very interesting chemical and physical properties. Our group mainly focuses on two aspects of these strong interactions. They are broadly divided under the umbrella of chemistry and material science.
Polaritonic Chemistry:
Strong coupling of light to a vibrational transition should affect chemistry because it offers a simple way to modify a given chemical bond and, hence, its reactivity landscape. We control chemical reactions by selective coupling of molecular states to confined photons.
Polaritronics:
Here, more emphasis will be given to improving the efficiency of energy and electron transport in molecular materials via the polaritonic states; a new field of research coined as ‘polaritronics’. Such systems will be tested in a home-built electro-optical workstation and apply them for quantum transport and sensing applications.
