Tuesday 20th March: STP Seminar – “From Hilbert’s 16th Problem to Physics”

Title: From Hilbert’s 16th Problem to Physics Speaker: Charles Nash (NUI Maynooth) Abstract: We shall describe a link between Hilbert’s sixteenth problem (part (i)) concerning real algebraic curves and condensed matter physics. The central result is some work of Kenyon and… Read More

Tuesday 6th March: STP Seminar – “Quantum Correlations in Space & Time”

Title: Quantum Correlations in Space & Time Speaker: Joe Fitzsimons (Singapore University of Technology and Design) Abstract: In ordinary, non-relativistic, quantum physics, time enters only as a parameter and not as an observable: a state of a physical system is specified… Read More

Tuesday 27th February: STP Seminar – “Anomalous Transport”

Title: Anomalous Transport Speaker: Karl Landsteiner (Universidad Autónoma de Madrid) Abstract: The concept of symmetry is one cornerstone of modern theoretical physics, quantum mechanics is another. Sometimes they are incompatible with each other. These incompatibilities are called anomalies. They constrain possible… Read More

Thursday 15th March: STP Seminar – “Einstein Gravity From Conformal Field Theory”

Title: Einstein Gravity From Conformal Field Theory Speaker: Andrei Parnachev (TCD) Abstract: We will analyse the Regge limit of certain four point functions in CFTs and will argue that holographic CFTs must be described by the Einstein gravity. Time: Thursday 15th… Read More

Tuesday 13th February: STP Seminar – “An Introduction to Causal Set Theory”

Title: An Introduction to Causal Set Theory Speaker: Dionigi M.T. Benincasa (DIAS) Abstract: Causal set theory is a sum-over-histories approach to quantum gravity, where the histories are discrete spacetimes (called causal sets) defined as locally finite partial orders. Causal sets were… Read More

Tuesday 6th February: STP Seminar – “A Hopf algebra for Feynman diagrams and integral”

Title: A Hopf algebra for Feynman diagrams and integral Speaker: Ruth Britto (Trinity College Dublin) Abstract: I will present a combinatorial operation on one-loop Feynman diagrams, described by cutting and pinching edges, that corresponds to the Hopf-algebraic coaction on the… Read More

Tuesday 5th December: STP Seminar – “An M5-Brane Model”

Title: An M5-Brane Model Speaker: Christian Sämann (Heriot-Watt University) Abstract: We show how to write an action for a classical six-dimensional superconfomal field theory containing a non-abelian tensor multiplet. All of the ingredients of this action have been available in… Read More

Thursday 30th November: STP Seminar – “Commuting Matrices, MacDonald Identities & Supersymmetric Gauge Theory”

Title: Commuting Matrices, MacDonald Identities & Supersymmetric Gauge Theory Speaker: Giovanni Felder (ETH Zurich) Abstract: I will introduce the notion of representation homology, following Berest, Khatchatrian and Ramadoss, and discuss some examples, applications and open problems about pairs of commuting… Read More

Thursday 7th December: STP Seminar – “Quantum Aspects of Black Hole and Fuzzy Sphere in String Theory”

Title: Quantum Aspects of Black Hole and Fuzzy Sphere in String Theory Speaker: Yoshifumi Hyakutake (Ibaraki University, Japan) Abstract: One of important directions in superstring theory is to reveal quantum nature of black hole. In this talk we embed Schwarzschild… Read More
