Theoretical Condensed Matter Physics and Quantum Dynamics

Condensed matter physics deals with phenomena on the energy scales that are much smaller compared to the microscopic ones (for instance, the kinetic energy of electrons in metals corresponds to temperatures of about 10 000°, far higher than room temperature). Systems of many interacting particles at such macroscopic energy scales often behave in a qualitatively different way leading to so-called emergent phenomena. For example, low energy emergent excitations resulting from a “coherent dance” of electrons interacting with the crystal lattice or amongst themselves may not resemble electrons at all. In the celebrated example of carbon monolayer — graphene, electrons while scattering off the crystal lattice, lose their mass and behave like relativistic fermions. In superconductor, electrons pair with each other leading to an emergent quantum-coherent condensate of cooper pairs that can carry an electric current without any resistance.

While microscopically we cannot alter the basic laws of nature, one of the goals of condensed matter physics is to explore and extend the possible range of emergent behaviors. My research is concentrates on uncovering new emergent physics in quantum systems.

One direction of my research pertains to the dynamics of isolated quantum many-body systems. Such dynamics are currently being studied in systems of cold atoms, trapped ions, superconducting qubits, and many others; these are often referred to as “artificial quantum matter”. The presence of strong disorder in such systems may lead to a so-called many-body localized phase, wherein the system fails to reach thermal equilibrium and cannot be described by usual statistical mechanics. The possibility of evading thermal equilibrium, in which the system quickly turns into “featureless hot soup”, is not only interesting from a practical point of view, but can also potentially enable deeper insight into the emergence of statistical mechanics in a variety of quantum systems.

The second direction of my research pertains to probing and exploring interesting emergent physics in the context of solid-state systems. I am interested in unconventional superconductors, systems with spin-orbit coupling, Dirac and topological materials.  I am particularly attracted to theory that is immediately connected with experiments, either explaining existing data or leading to potentially observable predictions.
