My research area spans cold Rydberg physics and quantum information processing. Cold atoms are ubiquitously employed as a promising platform for realizing scalable quantum computing, owing to their strong and tunable long-range interactions in simulating conditional logic gates. Applications include designing quantum gates, such as entangling gates, to create maximally entangled ensembles of atoms distributed over a network of atomic clocks. This can serve to increase  stability of optical lattice clocks, as well as creating a distributed computing platform which takes full advantage of quantum entanglement.

Research problems I am normally interested in involve Rydberg atoms. I have been extensively investigating atomic processes in Rydberg atoms, such as Rydberg-Rydberg interactions, electron-impact ionization, high-harmonic generation, and cascade/excitation/ionization in static and time-dependent external fields. Correspondence between classical and quantum mechanics can easily be studied in these systems, which opens a door for understanding dynamical chaos on a quantum level. I am also interested in problems involving interactions of atoms with strong laser fields, and a variety of rich and interesting phenomena that result from such interactions.  

My research interests cover a range of problems whose solution typically relies on either  numerical simulations of dynamical processes, or on perturbative calculations of atomic properties. The former involves numerical propagation of the time-dependent Schrodinger equation to study non-perturbative physics. These problems are computationally intensive and I make use of various numerical schemes as well as parallel computation.
