Title: Quantum transport in many-body quantum systems: Theory and Experiments
Speaker: Dario Poletti
Time: Nov. 7th (Tue.), 10:00
Location: Room 215
Abstract:
As in many-body quantum systems one can observe the emergence of different phases of matter, when they are coupled to baths interactions can lead the system to have very different transport properties. Can allow an interesting degree of control of transport at the quantum scale. In this talk we aim to give an overview of quantum transport in many-body quantum systems, with an emphasis on models and phenomenology. We will then discuss the experimental testing on quantum simulators. For this we will show a novel approach based on pure state statistical physics. We will show that this allows the study of non-equilibrium steady states, typically needing thermodinamically large baths, in finite and close quantum systems. More specifically we will show how non-equilibrium steady states properties can be probed and tuned, at the single component level, on superconducting quantum processors. We will conclude with an outlook on possible future directions.
