SPS Journal Club: ‘Probing the Rigidity of String Theory’
IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, SpainJournal clubs_enSpeaker: Georgina Staudt (Max Planck Institute Munich) Venue&Time: Red Room / 12:00 Abstract: We investigate the deformability of the Veneziano amplitude. If string theory is the unique theory of quantum gravity, the tree level amplitudes of weak coupling limits should be non-deformable. We make progress in this direction for tachyon-free superstring theories by deriving a […]

DIFT Colloquium: ‘Gamma Ray Bursts, Cosmic Rays and the Sociology of Science’
AULA POLIVALENTE UAM Plaza Mayor Campus de Cantoblanco UAM. C. Einstein, 7, Fuencarral-El Pardo, 28049 Madrid, Madrid, Madrid, SpainSeminars_esSpeaker: Álvaro de Rújula from IFT & CERN Venue & Time: Aula Polivalente UAM Abstract: Gamma-Ray Bursts (GRBs) and Cosmic Rays (CRs) are not difficult to comprehend. Quasars and micro-quasars are seen to emit highly relativistic “Cannonballs” (CBs), though the underlying mechanism remains unfathomable. The observation that core-collapse supernovae also emit CBs —plus some trivial […]

Old Journal Club: ‘Renormalization and Effective Lagrangians’
Blue Room Instituto de Física Teórica (IFT) - C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, SpainJournal clubs_enPau Garcia Romeu (IFT) will present Renormalization and Effective Lagrangians by Joseph Polchinski. Venue&Time: Blue Room / 17:00 Abstract: There is a strong intuitive understanding of renormalization, due to Wilson, in terms of the scaling of effective lagrangians. We show that this can be made the basis for a proof of perturbative renormalization. We first […]

Open String Axiverse
IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, SpainJournal clubs_enSpeaker: Giovanni Villadoro from ICTP Venue & Time: Red Room / 15:00 Abstract: Localized charged fields are a general feature of many realistic string compactifications. I will review how in four dimensions they can lead to a multitude of perturbatively-exact global symmetries that, when spontaneously broken, generate a new axiverse compatible with post-inflationary evolutions.

Pheno Journal Club: Coherently enhanced decoherence and cloud substructure of atom interferometers
Gray Room 3 Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, SpainJournal clubs_enSpeaker: Pablo Blanco Mas (IFT) Venue & Time: Grey Room 3 / 15:00 Abstract: We study how coherent scattering of a background gas off an atom (or other matter) interferometer can lead to enhanced signals from phase shifts and contrast loss. We focus on the inclusion of realistic features of atom interferometers such as finite temperature, […]

Bubble wall dynamics from nonequilibrium quantum field theory
IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, SpainJournal clubs_enSpeaker: Matthias Carosi from Munich, Tech. U. Venue & Time: Red Room / 15:00 Abstract: First-order phase transitions in the early universe are a unique probe of physics beyond the Standard Model, with potential implications for electroweak baryogenesis, the formation of primordial black holes, magnetogenesis and the production of dark matter. Upcoming gravitational wave detectors may […]

Old Journal Club: S. W. Hawking, Black holes and thermodynamics
Blue Room Instituto de Física Teórica (IFT) - C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, SpainJournal clubs_enChristian Aoufia (IFT) will present S. W. Hawking, Black holes and thermodynamics, Phys. Rev. D, vol. 13, no. 2, pp. 191–197, 1976. doi: 10.1103/PhysRevD.13.191 Venue & Time: Blue Room / 17:00 Abstract: The concept of entropy is examined with an eye toward gaining insight into the nature of black-hole thermodynamics. Definitions of entropy are given for […]
