ITAMP Seminar (Note the unusual time and place)

Speaker: Benoit Vermersch (IQOQI Innsbruck)

Date: Friday, July 28th
Time: 10:30am-12:00pm
Location:  Pratt conference room @ Center for Astrophysics (60 Garden Street)

Title: 
Measuring entanglement in many-body quantum systems.

Abstract: 
In the first part of my talk, I will show how to measure the entanglement spectrum of ground states of generic Hamiltonians based on the direct engineering of the entanglement Hamiltonian [1]. Our method, based on the Bisognano-Wichmann theorem, allows to measure the entanglement spectrum via spectroscopy techniques. I will provide numerical examples to support this result and give examples of AMO implementations of entanglement Hamiltonians.

In the second part of my talk, I will present a method to measure Renyi entropies using random quenches. I will illustrate our approach in the context of 2d Hubbard (ultracold atoms) and Quantum Ising (Rydberg atoms, trapped ions) models.
