DESCRIPTION:Speakers: Katharina Wölfl\, Jakob Hollweck\, Martin Ammon\, F
ederico Capone\n\nThe first edition of the TPI School focuses on quantum e
ntanglement and generalized symmetries in QFT and Holography. While the fo
rmer topic is long known to play a crucial role in our understanding of su
ch theories\, the latter has recently attracted the attention of the scien
tific community. The aim of the School is to form PhD students and postdoc
toral researchers in these fields and discuss the connections of these tw
o very hot topics...in cool weather! \n\nThe School comprises two in-dept
h classes\, each involving about ten hours of blackboard lectures and tuto
rials. We are delighted that our lecturers are \n\nNele Callebaut (Instit
ute for Theoretical Physics\, University of Cologne\, Germany)\n\nNabil Iq
bal (Department of Mathematical Sciences\, Durham University\, UK). \n\nP
articipants are strongly encouraged to contribute to the scientific activi
ty by registering to the gong-show\, planned on the 14th of February\, or
via a poster. Contributing students can apply for partial funding until t
he 15th of December 2023.\n\nRegistration is open until 20 Jan 2024.\n\n
\n\nProgram\n\nEntanglement in CFT and Holography - Nele Callebaut\n\nIn
these lectures we give a pedagogical account of the replica trick derivat
ion of CFT entanglement and its holographic counterpart\, i.e. the Lewkowy
cz Maldacena derivation of the Ryu-Takayanagi formula. The application to
an 'island set-up' for the calculation of black hole radiation entropy is
briefly discussed. Further topics focused on are the relation to thermal e
ntropy\, thermofield double constructions and statements about the emergen
ce of gravity from entanglement through reinterpretations of gravitational
first laws.\n\nIntroduction to Generalized Symmetries: Principles and App
lications - Nabil Iqbal\n\nSymmetries are one of our most fundamental tool
s in the understanding of nature. We have recently learned of a new way to
think about global symmetries in quantum field theories. Just as ordinary
global symmetries are associated with a conserved density of particles\,
the new concept of higher-form symmetries are associated with a density of
extended objects\, such as strings and branes. Similarly\, Non-invertible
symmetries refer to symmetry operations where the charge generators don
’t satisfy a simple group conservation law. Such symmetries exist in ver
y familiar systems and present the possibility of constructing a new enlar
ged Landau paradigm that will include all of the phases of the matter. I w
ill provide an elementary introduction to these new generalized symmetry p
rinciples and present some applications to gauge theories\, statistical ph
ysics\, and hydrodynamics.\n(I’ll assume basic knowledge of quantum fiel
d theory\; exposure to conformal field theory will also be helpful).\n\n
