  • Muon g-2: nuts and bolts and lattice QCD

    IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain
    Scientific activities

    Speaker: Andreas Kronfeld (Fermilab) Venue&Time: Red Room / 3:00 PM Abstract: This seminar consists of two parts. First, it is discussed how various approaches to the hadronic vacuum polarization (HVP) for the anomalous magnetic moment of the muon, g-2, are connected. Second, results for the HVP from lattice QCD are presented, focusing on the work […]

  • SPS Journal Club: ‘Landau-Ginzburg Models and Flux Vacua’

    IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain
    Journal clubs

    Speaker: Muthusamy Rajaguru (IFT Madrid) Venue&Time: Red Room / 12:00 PM Abstract: In this talk, I will give an overview of recent progress that has been made in constructing non-geometric flux vacua. In particular, I will focus on type IIB string compactifications where the internal geometry is described by the 2^6 and 1^9 Landau-Ginzburg (LG) models. These […]

  • Fast inference for slow likelihoods with probabilistic machine-learning

    IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain
    Scientific activities

    Speaker: Jesús Torrado from IEM-CSIC Venue&Time: Red Room / 3:00 PM Abstract: Inference for slow likelihoods can require weeks or months, if possible at all, with traditional Monte Carlo samplers. This would be the case, for example, when fitting expensive non-linear matter spectrum models, or when characterizing individual long-duration GW events. I will introduce a […]

  • César Gómez (1954–2025): A rich life in theory

    Blue Room Instituto de Física Teórica (IFT) - C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain
    Scientific activities

    Venue&Time: Blue Room / 10:20 – 17:30 More info: workshops.ift.uam-csic.es/CesarGathering/ César Gómez, whose profound contributions to gauge theory, string theory and quantum gravity were matched by his vision and generosity, passed away on 7 April 2025. After earning his PhD in Salamanca, he held positions at Harvard, the IAS and CERN before joining the CSIC […]

  • SPS Journal Club: Symmetric Moduli Spaces, the Swampland Distance Conjecture (…and the Emergent String Conjecture?)

    IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain
    Journal clubs

    Speaker: Bernardo Fraiman (IFT) Venue&Time: Red Room / 12:00 Abstract: For non-compact, locally symmetric moduli spaces M, the set of geodesics and the geometry of the boundary can be completely characterised using group theory. Under the assumption that M is "compactifiable" and some mild conditions on the spectrum of states, we prove the SDC for […]

  • Large neutrino mass in cosmology and keV sterile neutrino dark matter from a dark sector

    IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain
    Scientific activities

    Speaker: Thomas Schwetz from Karlsruhe Institute of Technology (KIT) Venue&Time: Red Room / 3:00 PM Abstract: Recent results from cosmology place sever upper bounds on the sum of neutrino masses, starting to be in conflict with lower bounds from neutrino oscillations. If this neutrino tension persists, it may indicate new physics in cosmology and/or neutrino […]

  • Holo Club: Explicit Connections Between Krylov and Nielsen Complexity

    Gray Room 3 Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain
    Journal clubs

    Speaker: Le-Chen Qu (IFT) Venue&Time: Grey Room 3 / 11:30 Abstract: We establish a precise correspondence between Krylov complexity and Nielsen complexity in quantum many-body systems. By identifying the Krylov basis with the generators of elementary gates in Nielsen's geometric framework, the Krylov complexity of precursor operators acquires a geometric interpretation as the length of […]
