Quantum information in curved spacetime

(NTMF095NTMF082, spring term 2023/24)

 

Lecturer: David Kubiznak (david.kubiznak@matfyz.cuni.cz)

Institute of Theoretical Physics, MFF UK

Dotation: 2/0, oral exam

 

Description

We will cover the basics of the gauge/gravity duality, including some of the following aspects: holographic RG flows, fluid/gravity correspondence, applications to condensed matter systems, holographic entanglement entropy, and recent advances in understanding the black hole information paradox. For PhD and Mgr students – basic knowledge of general relativity and quantum field theory is required.

 

Preliminary topics

 

Exam

You will be asked one theoretical and one computational question out of the following two sets. You will have 30 minutes to prepare your answers. After that, we will discuss your answers together with some (un)related problems. The discussion should last about 30 minutes, after which I will provide my feedback to you.
