Current Research
Synthetic and non-equilibrium condensed matter
Topological signatures are widespread in various synthetic topological metamaterials and non-equilibrium setups, with potential applications in photonics and electronics. Non-equilibrium effects lead to a number of new phenomena such as unconventional critical scaling behavior and novel bulk-boundary correspondences.
Specific directions include:
- non-Hermitian dynamics and phase transitions
- Floquet engineering of new phases
- topological photonics, mechanics and circuits
- topology of non-linear dynamics
- non-equilibrium complex networks
Strongly correlated systems
My group also explores the intriguing interplay of energetics and topology on strongly interacting particles. Current directions include:
- entanglement entropy and conformal field theory
- fractional quantum Hall systems
- Simulation of topological and non-unitary systems on quantum computers
