Pheno Journal Club: ‘Is the Strong CP Problem Really a Problem?’
Gray Room 3 Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, SpainJournal clubsSpeaker: Giulio Barni (IFT) Venue & Time: 14:30 – 15:30 Abstract: The vanishingly small value of the QCD θ-angle inferred from neutron EDM bounds is usually taken as evidence for the Strong CP Problem, prompting a wide range of proposed solutions. In this talk, I will first review what the Strong CP Problem is: why […]

String, Pheno and the Swampland Journal Club: ‘Anomaly-induced vanishing of brane partition functions’
IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, SpainJournal clubsSpeaker: Michelangelo Tartaglia (IFT) Venue & Time: Red Room / 12:00 Abstract: In the presence of 't Hooft anomalies, backgrounds for the symmetries of a quantum field theory can lead to non-conservation of Noether currents, or more generally, to the presence of charged insertions in the path integral. When there is a net background charge, […]

Holo Club: ‘Complexity equals anything for multi-horizon black holes’
Gray Room 3 Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, SpainJournal clubsSpeaker: Hong-Yue Jiang (Lanzhou University) Venue&Time: 11:30 / Gray Room 3 Abstract: We investigate the ``complexity equals anything" proposal with codimension-one and codimension-zero gravitational observables for multi-horizon black holes, using the Bardeen-AdS class black hole as an example. In particular, we compare the results with the ``complexity equals volume" (CV) proposal and find that the […]

Quantum Information Journal Club: ‘Programming quantum matter made with light and atoms’
Gray Room 3 Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, SpainJournal clubsSpeaker: Cristian Tabares Venue & Time: 11:30 / Gray Room 3 Abstract: Current experimental quantum devices do not yet meet the requirements for building fault-tolerant quantum computers, but they can still be used to address many-body problems as analogue quantum simulators. Furthermore, recent experimental advances are enabling these simulators to operate in a programmable manner , […]

SPS Journal Club: ‘On the K-point in moduli space’
IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, SpainJournal clubsSpeaker: Alessandra Grieco (IFT) Venue & Time: Red Room / 12:00 Abstract: We study a class of infinite-distance loci, referred to as K-points, in one-parameter complex-structure moduli spaces of type IIB string theory compactified on Calabi-Yau manifolds. We show that around K-points the effective four-dimensional supergravity exhibits certain unusual properties. The two most prominent being […]

Old Journal Club: ‘Field Theories with Superconductor Solutions’
Blue Room Instituto de Física Teórica (IFT) - C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, SpainJournal clubsLorenzo Paoloni (IFT) will present :“Field Theories with Superconductor Solutions", Nuovo Cim. 19 (1961) 154–164 de J. Goldstone. Venue & Time: Blue Room / 17:00 Abstract: The conditions for the existence of non-perturbative type « superconductor » solutions of field theories are examined. A non-covariant canonical transformation method is used to find such solutions for […]

Pheno Journal Club: ‘How large can lepton mixing be?’
Gray Room 3 Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, SpainJournal clubsSpeaker: Sergio Rodríguez Benítez (IFT) Venue & Time: Grey Room 3 / 15:00 Abstract: We show that, contrary to common expectations, the observed charged leptons can have a substantial mixing with new heavier fermions, at the level of 20%. This can happen, in the language of effective theories, when the effect of mixing with heavier […]
