Holography: Entangled, Applied, and Generalized

Europe/Copenhagen
Description
General

This PhD school in Copenhagen will give PhD students and other interested researchers a state-of-the-art introduction to a number of recent exciting topics in gravity and string theory with a particular focus on entanglement entropy and applications of holography. The course is intended for PhD students and other researchers working in theoretical high energy physics, cosmology and mathematics, but some of the courses (see below) may also be interesting for those working in the area of theoretical condensed matter physics. The school is organized by the Theoretical Particle Physics and Cosmology Group  and will be held at the Niels Bohr Institute in Copenhagen. The course is also an event of the DFG school Models of Gravity.

The deadline for registration is September 14. Participation in the school is free. For participants coming from outside Copenhagen there may be support available for local accommodation. For those wishing to be considered for support, there is an earlier deadline August 31. Those that cannot be supported, or do not need support, can find information on affordable accommodation possibilities on this page.

Scientific Programme

External lecturers
  • Alejandra Castro (University of Amsterdam): 3D Quantum Gravity: A Survey on Non-Perturbative and Non-Local Effects 
  • Jelle Hartong  (Université Libre de Bruxelles): Newton-Cartan Geometry in Holography and Condensed Matter Theory 
  • Tadashi Takayanagi (Kyoto University & IPMU): Entanglement Entropy and Holography
For abstracts of the lectures see the Scientific Programme page in the menu. See also the timetable (subject to minor changes).

Format

On each day there will be one 2-hour morning lecture and one 2-hour afternoon lecture. The 2-hour lectures are divided into two blocks of 50 minutes with a 20 minute coffee break in between. This will provide an extra opportunity for lecturers and students to interact. Further on three afternoons there will be 1-hour exercise sessions.

Dinner

A dinner for all participants will be organized on Tuesday evening; details TBA.

Guided tour of the NBI

We will organize a guided tour of the Niels Bohr Institute during which you will hear about the works and life of Niels Bohr and his contemporaries.  The tour starts at the reception and will be given by Felicity Pors from the Niels Bohr Archive.

Sponsor This PhD school is funded by the Faculty of Science of the University of Copenhagen, the Rosenfeld Foundation, the Niels Bohr Fund, and the Niels Bohr International Academy.

      Seminar: Gravity Dual of Quantum Information Metric 1h Aud. A (NBI)

      Aud. A

      NBI

      We study a quantum information metric (or fidelity susceptibility) in conformal field theories with respect to a small perturbation by a primary operator. We argue that its gravity dual is approximately given by a volume of maximal time slice in an AdS spacetime when the perturbation is exactly marginal. We confirm our claim in several examples.

      Aud. A

      NBI

      After a brief review of holographic techniques derived from the AdS-CFT correspondence, we specialize to a class of spacetimes proposed as duals to non-relativistic systems. We highlight classical and quantum features of these "Lifshitz spacetimes" which limit the reconstructability of bulk spacetime information from boundary data. We additionally discuss the fate of various spacetime reconstruction procedures in Lifshitz spacetimes.

      Mini introductory course on holography for space-times that are no longer asymptotically AdS but instead for example conformally AdS, Lifshitz or Schroedinger. Such cases are interesting for potential applications to condensed matter theory, black hole physics (Kerr/CFT, subtracted geometry) and for generalizing our notions of holography.
