Theory and Simulation of Complex Quantum Matter

The group focuses on the theory and simulations of complex quantum matter emerging in quantum simulators made of ultracold atoms and molecules using both analitical techniques and quantum algorithms. Their work spans topological phases, vortex dynamics, strongly frustrated quantum systems, and lattice gauge theories, with an emphasis on uncovering emergent phenomena beyond conventional paradigms.
