Aspects of inflation beyond the single-field, slow-roll regime

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

PhD Dissertation_es

Speaker: Alejandro Pérez Rodríguez Location&Place: Red Room Abstract: In this thesis, we explore two departures from the single field, slow-roll paradigm of inflation. The first part is dedicated to warm inflation. We revisit the theory of linear perturbations in this framework, develop computational techniques for the calculation of the primordial power spectrum and apply them to […]

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

Seminars_es

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

Seminars_es

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 […]

God plays dice with the world. The story of quantum mechanics

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

Seminars_es

What is matter? A question that has fascinated—and at times tormented—some of the brightest minds of the twentieth century. Max Planck, Albert Einstein, Niels Bohr, Erwin Schrödinger, Werner Heisenberg, Max Born, Wolfgang Pauli, and Paul Dirac all grappled with it, debating fiercely, colliding over equations and experiments, in their attempt to decipher the very essence of […]

PhD Dissertation_es

Gonzalo Morrás PhD dissertation. Supervisor: Juan García-Bellido Venue&Time: Blue Room / 10:30 AM Abstract: Gravitational wave (GW) astronomy has opened a new window onto the Universe, allowing us to study compact objects and fundamental physics. This thesis develops new methods and models to improve the detection and interpretation of GW signals, with a focus on […]

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_en

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

Seminars_es

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_en

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 […]
