Spacetime as a resource

Regular Seminar Joan Simon (U. of Edinburgh)

at:
14:00 QMW
room G O Jones 610
abstract:

The relation between black holes and thermodynamics leading to the holographic principle is well known. Formulating thermodynamics as the theory of transformations performing some work or task allows us to reinterpret recent developments in AdS/CFT, such as the holographic description of entanglement entropy, as a measure of the connectivity of space (resource). Whether spacetime in the interior of a black hole also allows an understanding as a resource is an interesting open question.

Quantum entanglement of localized excited states at finite temperature

Regular Seminar Joan Simon (University of Edinburgh)

at:
13:15 KCL
room G.01
abstract:

Motivated by either condensed matter or quantum gravity holographic considerations, I will discuss some preliminary work on how to compute the time evolution in Renyi entropies in 2d CFTs in the large c limit for thermal states perturbed by localized primary operators. Time permitting, I will comment on the potential relation between this work and previous holographic calculations in the context of the EPR=ER conjecture.

Extremal black holes: a status report

Regular Seminar Joan Simon (Edinburgh)

at:
14:00 QMW
room 602
abstract:

I will review some recent attempts at providing a microscopic description for extremal black holes. First, I will explain a constituent model for extremal non-rotating non-BPS asymptoticaly flat black holes. Second, I will summarise the main claims in the so called extremal BH/CFT correspondence, pointing out how a chiral CFT can emerge as a limit of a non-chiral CFT. Finally, I will use R-charge AdS black holes to derive the existence of emergent IR CFTs, similar to the ones that have been argued to capture some interesting quantum criticality phenomena in some strongly coupled condensed matter systems.
