Measuring Stochastic Gravitational Wave Backgrounds with Pulsar Timing Arrays

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

Scientific activities

Speaker: Mauro Pieroni Institution: IEM-CSIC Location&Place: Red Room Abstract: My talk focuses on using Pulsar Timing Array (PTA) data to measure Gravitational Waves (GWs). In particular, I will focus on Stochastic GW Background (SGWB) measurements. After a general introduction to the topic, I will discuss a new (simplified) approach to constrain SGWBs with PTA data.

Vacuum stability for gravity compactifications

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

Scientific activities

Speaker: Alessandro Tomasiello (Milano Bicocca) Venue&Time: 15:00 / Red Room Abstract: Compactifying from higher dimensions typically produces many different vacuum solutions; this leads to multiple possible decay channels, mediated by the nucleation of bubbles. In string theory, the latter can be expanding D-branes. Supersymmetry provides a stabilization mechanism; I will describe how to replicate it […]

QIJC: Higher Abelian Quantum Double Models: Introduction to the Characterization and Classification of the Ground State Subspace

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

Journal clubs

Quantum Information Journal Club Speaker: Javier Ignacio Lorca Espiro (Universidad de la Frontera, Chile) Venue&Time: Grey Room 3 / 11:30 AM Abstract: Higher dimensional abelian quantum double models have been shown to be well defined in any finite dimension and exhibit the characteristic behavior of SPT phases models. In this talk, we will introduce the […]

Kaluza-Klein Amplitudes in AdS: the Virasoro-Shapiro and the Veneziano Amplitudes

Scientific activities

Speaker: Bo Wang from Zhejiang U. Inst. Mod. Phys. Venue&Time: Red Room / 3:00 PM Abstract: I will report recent progress on AdS Virasoro-Shapiro and Veneziano amplitudes for half-BPS operators with arbitrary Kaluza-Klein modes. The key ingredient is a bootstrap built directly in the world-sheet representation, together with a novel formalism. This approach yields a […]

SPS JC: de Sitter and Machine Learning

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

Journal clubs

SPS Journal Club Speaker: Bruno De Luca Venue&Time: Red Room / 12:00 Abstract: The problem of constructing de Sitter vacua in quantum theories of gravity is constrained by no-go theorems and made computationally challenging by the absence of supersymmetry. A popular approach to make it more tractableis to start from a supersymmetric compactification, such as […]

Stirring up the intracluster medium with substructures

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

Scientific activities

Speaker: Go Ogiya from Zhejiang University Venue&Time: Red Room / 3:00 PM Abstract: The origin of the turbulent motion of the intracluster medium (ICM) has been a longstanding open question. Stirring by substructures (member galaxies and dark matter subhaloes) orbiting within a galaxy cluster is a possible mechanism to generate and maintain the ICM turbulence. […]

To bind or not to bind, a tale of two nucleons

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

Scientific activities

Speaker: André Walker-Loud (LBNL) Venue&Time: Red Room / 11:30 AM Abstract: Our ability to understand the emergence of nuclear physics from the Standard Model requires an understanding two nucleon interactions from the underlying quark and gluon degrees of freedom. Due to the non-perturbative nature of QCD at low-energies, the only method to provide such predictions, […]

Delta N formalism: non-linear evolution of scalar and tensor perturbations during inflation

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

Scientific activities

Speaker: Danilo Artigas Institution: Kyoto University Location&Place: IFT Seminar Room/Red Room Abstract: Linear-perturbation theory has proven to be an extremely powerful tool to compare inflationary models with observational data. Recently, the newcoming high-precision observations call for predictions beyond linear perturbations. Such effects are known to be relevant for example in the production of primordial black […]
