The DRSTP Postgraduate AIO/OIO School 2015 Literature/abstracts First week: Ana Achúcarro (Leiden University, the Netherlands): From inflation to dark energy Abstract: The course will present the concepts of modern cosmology and the great advances made during the last decade, both theoretically and observationally. Cliff Burgess (McMaster University, Canada): Physics beyond the standard model Abstract: The goal of the lectures is to present generic BSM ideas that could be relevant to the physics of the LHC, and that could help understanding the phenomenon of Electroweak Symmetry Breaking, as well as other open questions in the Standard Model of Particle Physics. Carlos Nuñez (Swansea University, UK): Lectures on gauge/gravity duality Abstract: The goal is to introduce the fundamental properties of the AdS/CFT duality through models that have a welldefined construction within superstring theory. Second week minicourse lectures: Nima ArkaniHamed (IAS Princeton,New Jersey, USA):Scattering amplitudes and the amplituhedron In these lectures, a new formulation for scattering amplitudes in planar N=4 SYM will be described where the usual picture of unitary evolution though spacetime is not primary. Instead, amplitudes are associated the “the volume” of a new geometric object, “the Amplituhedron”, closely connected to another object studied by algebraic geometers and physicists in recent years, known as “the Positive Grassmannian”. It wil be described how locality and unitarity arise as derived notions from the positive geometry. The following reading material is recommended: (1) There is an excellent review of scattering amplitudes by Elvang and Huang, arXiv:1308.1697 (2) The Introduction of this early paper of ArkaniHamed and Cachazo, arXiv:0808.1446 (3) The positive grassmannian paper arXiv:1212.5605 (4) The amplituhedron paper arXiv:1312.2007 Jan de Boer (University of Amsterdam, the Netherlands): Entanglement entropy and its uses In these lectures we first review a few basic notions from quantum information theory with an emphasis on entanglement and its properties. We then discuss properties of entanglement in various systems, how they can be used to diagnose various phases, and how it can be computed in weakly and some strongly coupled field theories. Finally, we will discuss some aspects of the relation between entanglement and spacetime geometry that has emerged in recent years. some reading: * Lindesay, Susskind, “An introduction to black holes, information, and the string theory revolution”, world scientific, 2005 * chapter 2 and 4 of the lectures notes of John Preskill, http://www.theory.caltech.edu/~preskill/ph219/index.html#lecture * Daniel Harlow, Jerusalem lectures on black holes and quantum information, http://arxiv.org/abs/1409.1231 Cumrun Vafa (Harvard University, Massachusetts, USA): Topological strings and supersymmetric amplitudes Reading material: arXiv:1412.4793 Twistorial Topological Strings and a tt* Geometry for N=2 Theories in 4d Sergio Cecotti, Andrew Neitzke, Cumrun Vafa arXiv:1312.1008 [pdf, other] tt* Geometry in 3 and 4 Dimensions Sergio Cecotti, Davide Gaiotto, Cumrun Vafa arXiv:hepth/0410178 Topological strings and their physical applications Andrew Neitzke, Cumrun Vafa Topological antitopological fusion (Download pdf here) Sergio Cecotti (SISSA, Trieste & INFN, Trieste), Cumrun Vafa (Harvard U.).
