Outline

We perform research in theoretical condensed matter physics, atomic physics, quantum information, computational physics, transport phenomena, energy conversion and solar energy. Our research work is interdisciplinary and also explores the interface between atomic physics, quantum optics, nano-science, and computing. We are also studying superconducting Josephson-junction qubits, nano-mechanics, hybrid quantum electro-mechanical systems, quantum nano-electronics, quantum emulators, artificial photosynthesis, and light-to-electricity conversion. An underlying theme of our work is to better understand nano-scale quantum systems and devise methods to control them. We use physical models to make predictions that can be tested experimentally and that can be used to better understand the observed phenomena.

Results

Interdisciplinary theoretical investigations in atomic physics, quantum optics, and condensed matter physics, applied to quantum nano-electronics

Our group has obtained various new research results doing interdisciplinary theoretical and computational investigations in atomic physics, quantum optics, and condensed matter physics, in the context of engineered quantum nano-electronics. We have uncovered new phenomena in semi- and super-conducting electrical devices, behaving as artificial atoms, which provide an unprecedented platform for experimentally realizing controlled and designable quantum systems. These devices allow the creation of circuit analogues and simulations of quantum phenomena from a wide range of fields of physics and chemistry. We also pioneered the study of electron vortex beams and other optics-like phenomena. Interdisciplinary research on this type (often in collaboration with experimentalists) will continue catalyzing discoveries and make new connections between various subfields of physics.
