Young Researchers Integrability School and Workshop (YRISW) 2019: A modern primer for 2D CFT Mitschnitt einer Veranstaltung des Internationalen Erwin Schrödinger Instituts für Mathematik und Physik (ESI) am Donnerstag, dem 14. Februar 2019 im Lise Meitner-Hörsaal der Fakultät für Physik Teil 20: Andrea Cavaglià: Deformations part 2.1 Kamera: Thomas Kroyer, Kenan Vrabac Schnitt: Daniel Winkler Abstract: This course will focus on a special type of deformation of two-dimensional quantum (not necessarily conformal) field theories driven by the determinant of the stress-energy tensor: the so-called T-Tbar deformation. We will study in detail the case where the deformed theory is a CFT, computing the effects of the T-Tbar-flow on various physical quantities and discussing some applications. Andrea Cavaglià ist Postdoktorand im Fachbereich Theoretische Physik am King's College in London.
