COOLIO · Controlled Dynamics in Cold Quantum Matter

Quantum physics lies at the heart of many phenomena in modern physics, from the microscopic world to in superconductors, topological insulators, and quantum magnets. In many cases the ground-state properties are understood, but dynamical processes in interacting quantum many-body systems largely evade a general understanding. One way of circumventing the computational complexity challenge is to engineer artificial model systems in order to quantum-simulate with high control the properties and dynamics of real-world quantum materials with the goal to identify the crucial ingredients of a specific quantum system and possibly to pinpoint universal properties. Performing faithful simulations of the dynamical response of interact-ing quantum many-body systems is one of the great frontiers in modern physics. The goal of COOLIO is to address an interconnected set of dynamical quantum simulation tasks with the aim to go significantly beyond the state-of-the-art and to significantly advance the understanding of dynam-ical phenomena in interacting quantum systems. The platform of choice are strongly-interacting one-dimensional bosons. With full parameter control we will investigate the transition from localization to chaos and thermalization in a driven quantum many-body system, test the limits of of generalized hydrodynamics in the emergence of Bethe string states, probe the anyonization of dressed bosons in a quantum transport experiment, test for transport and inhibition thereof in an attractively-interacting integrable system, and probe strongly-interacting chiral superfluids and their transition to insulating states in a coupled-spin system. With the completion of our newest 1D-bosons platform, for combining strongly interacting bosons with local readout and control, the project will be transformative as it will give unprecedented experi-mental access to higher-order correlations for dynamical quantum matter deeply in the quantum regime.
