Entanglement of a Relativistic Field in the Vacuum State
Benni Reznik - Tel Aviv University
We discuss gedanken experiments for measuring local and non-local observables in QFT that respect causality, and can by used to test the entanglement between two spatially distant regions in the vacuum. It is shown that the entanglement decays exponentially with the distance between the regions and…
The Quest for Localization
Juan José León García - Instituto de Física Fundamental (IFF - CSIC)
This talk aims to review the obstacles met in QFT to reach an appropriate definition for such a basic concept as localization. The anti-local character of the square root of the "- Laplace-Beltrami + mass^2" operator prevents the existence of localized states with a finite number of quanta. (Bosonic…
Pyrochlore Material Yb_2Ti_2O_7: A Model Quantum Spin Ice
We discuss the thermodynamic properties of the model exchange quantum spin ice material Yb_2Ti_2O_7. Using exchange parameters recently determined from high-field neutron scattering measurements, we calculate the thermodynamic properties of this model system. We find very good agreement with the…
Looking for Quantum Gravity in the Space of Conformal Field Theories
Joao Penedones - L'Ecole Polytechnique Federale de Lausanne (EPFL)
Conformal field theories have many applications ranging from continuous phase transitions in Statistical Mechanics to models of beyond the Standard Model physics in Particle Physics. In this talk, I will explain another remarkable application: some conformal field theories can be used to define and…

Dynamics of AdS-CMT Quenches
Toby Wiseman - Imperial College London
I will describe numerical simulations of quenches in AdS-CMT superconductors where we are able to construct a dynamical phase diagram for the system. I will describe how the late time behaviour is understood in terms of the quasinormal modes of the system, and how a rather generic behaviour of the…
