Vladislav Pokorný (Department of Condensed Matter Physics, MFF, Charles University and Department of Condensed Matter Theory, FZÚ AV ČR, v.v.i..)

Abstract: A single-level quantum dot connected to superconducting leads is an ideal system for studying the interplay between electronic correlations and the superconducting order. The proximity effect allows the Cooper pairs to leak into the quantum dot, opening a gap in its spectral function. Andreev reflections on the opposite interfaces give rise to discrete subgap states and the Coulomb interaction gives rise to the Kondo effect. This complex behavior in otherwise well controllable setup attracted a lot of attention in the past two decades and lead to many experimental...

Thomas Barthel (Department of Physics, Duke University)

Abstract: Entanglement entropies quantify non-locality and operational costs for quantum systems. In ground states of typical condensed matter systems, they obey area and log-area laws. In contrast, subsystem entropies in random and thermal states are extensive, i.e., obey a volume law. For energy eigenstates, one expects a crossover from the groundstate scaling at low energies and small subsystem sizes to the extensive scaling at high energies and large subsystem sizes. We elucidate this crossover. Due to eigenstate thermalization (ETH), the eigenstate entanglement can be related to...
