Abstract: The concept of a localized single impurity in a many-body system is at the base of some of the most celebrated problems in condensed matter. The aim of the PlusOne project is to realize the physical paradigm of a single localized impurity in a many-body system to advance quantum simulations of in- and out-of equilibrium many-body physics. Our quantum simulator will consist of a degenerate gas of fermions as a many-body system, with a single trapped ion playing the role of the impurity. We plan to realize an atom-ion hybrid system that can surpass all the limitations that prevent current systems from reaching full control of atom-ion interactions, allowing us to characterize atom-ion collisions in the so-far unexplored ultracold regime.
We will use the single trapped ion to study out-of-equilibrium dynamics of the many-body system by exploiting the entanglement generated in the joint evolution of the degenerate gas and the ion. By this mean, we plan to study the phenomenon of the Anderson Orthogonality Catastrophe and the thermodynamics of a system out of equilibrium by testing the seminal Tasaki-Crooks fluctuation relation in the quantum regime.
Finally, we will use the single trapped ion as a single atom probe and as a density- and time- correlation detector in a system of atoms loaded in an optical lattice. This achievement will significantly improve current methods for probing many-body physics with ultracold atoms.
