Vortex excitations and Josephson supercurrents in quantum bosonic mixtures
Mixtures of ultracold quantum gases offer an exceptional playground to study macroscopic quantum phenomena — from quantized vortices, the signature of superfluidity, and the phase separation to Josephson supercurrents. Our research explores the dynamics, the stability properties of massive quantum vortices, and the intervortex supercurrents they sustain. We are interested in how these systems give rise to emergent behaviors such as a chaotic dynamics and scattering effects, in the intriguing role of dipolar interactions and in the study of the vortex phenomenology in fluids of light and fermionic systems. These studies and their extension to lattice models pave the way toward innovative applications in the growing field of atomtronics.
Strongly interacting quantum matter
Our research focuses on the quantum simulation of strongly correlated and exotic phases of matter. We investigate topological phases, lattice gauge theories, and frustrated many-body systems using synthetic quantum materials based on ultracold atoms. By combining advanced tensor-network methods with the theoretical design of atomic quantum simulators, we aim to uncover emergent phenomena that are difficult or impossible to access with classical approaches. Our work bridges theory and experiment, providing insights into novel quantum states and offering pathways for their realization in state-of-the-art quantum platforms.
