Open String Axiverse

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

Speaker: 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, Spain

Journal clubs_en

Speaker: 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, […]

Speaker: 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 […]

Axion Physics

Gray Room 1 Instituto de Física Teórica, C/ Nicolás Cabrera 13-15, Cantoblanco, Madrid, Madrid, Spain

Journal clubs_en

Speaker: Giovanni Villadoro from ICTP Venue&Time: Grey Room 1 / 11:00 Abstract: Recent years have seen an increased interest in the phenomenology of the QCD axion and axion dark matter. In this lecture, I will review astrophysical and experimental bounds on axions, as well as the basics of axion detection experiments.

Recent results on the origin of Galactic CRs from gamma-ray astronomy

Speaker: Guillem Martí-Davesa (INFN-Trieste) Venue&Time: Red Room / 15:00 Abstract: Supernovae have traditionally been invoked as the dominant cosmic ray factories within our Galaxy, capable of accelerating protons up to PeV energies. In this seminar we will discuss to what extent such a view holds today, and if alternative source populations could instead be relevant […]

Seminar: ‘Entanglement asymmetry and spontaneously broken symmetries’

Seminars_es

Speaker: Eduardo García-Valdecasas (SISSA, Trieste) Venue&Time: Red Room / 15:00 Abstract: Entanglement asymmetry is a relative entropy that faithfully measures the breaking of a symmetry in a subregion. We explore some applications in theories with spontaneously broken higher form symmetries. We will start with discrete abelian symmetries and then discuss continuous symmetries. We will be […]
