SUMMARY:Groningen Scanning New Horizons Meeting (SNH2019)
DESCRIPTION:This meeting is part of the Dutch national program `Scanning New Horizons: Emergent Space-Time\, Black Holes and Quantum Information’ which is based upon a collaboration between the universities of Amsterdam\, Groningen\, Leiden and Utrecht. \nMay 24th\, 2019 @ Het Kasteel\, Melkweg 1\, 9718 EP Groningen. \nIt is a pleasant 15-minute walk from the Central Station. \n\nPROGRAMME \n10:30 Coffee/Tea \n11:15 Erik Tonni (SISSA) \nTitle: On entanglement hamiltonians in 1D free lattice models \n\nAbstract: The reduced density matrix can be written as the exponential\n of the entanglement hamiltonian\, hence this operator contains a lot of \ninformation about the entanglement of the bipartition when the entire \nsystem is in certain pure state. We discuss the derivation of the \nentanglement hamiltonian of an interval for a massless Dirac fermion\n in the ground state through the continuum limit of the corresponding\n lattice results in the free fermions chain. We also present numerical\n studies about the temporal evolution of the entanglement hamiltonians\n and of the contours for the entanglement entropy of an interval after\n a global quench in a harmonic chain and in a chain of free fermions. \n\n12:15 Lunch \n13:30 Julian Sonner (Geneva) \nTitle: Quantum Thermalization in AdS/CFT \nAbstract: via the AdS/CFT duality we can view black holes as thermal\nensembles of the dual field theory. In my talk I will report on several\ndetailed studies of low-dimensional examples such as 2D CFTs and\nSYK-like models\, which investigate and extend the scenario of\nthermalization via eigenstates as the boundary description of black\nholes and their dynamics. \n14:30 Coffee/tea \n15:00 Jeff Murugan (Kaapstad) \nTitle: Developments in randomness and chaos. \nAbstract: Motivated by trying to understand the difference between\nrandomness and true chaos in quantum many-body systems\, I will review a\nselection of recent developments in the field. I will focus on two\nexamples; the first is a variant of the more familiar SYK model while\nthe second is a new class of problem we call quantum small worlds. \n16:00 David Berenstein (Santa Barbara) \nTitle:Topology\, superposition and typicality in quantum gravity \nAbstract: I will describe recent advances in the study of quantum\n gravity where one can explicitly show in examples that superpositions\n of states with fixed topology can change the topology of spacetime.\n These effects lead to paradoxes that are resolved in effective field\n theory by the introduction of code subspaces. I will also talk about\n more typical states and issues related on how to decide if a \nblack hole horizon is smooth or not. \n17:00 Drinks \n
