Abstract: The $\epsilon$-expansion is a widely used technique to study aspects of renormalization group flows and critical phenomena. In this talk, I will discuss  recent developments of the $\epsilon$-expansion in the study of boundary and defect...

Abstract: I will argue on the possibility that compact extra dimensions obtain large size by higher dimensional inflation, relating the weakness of the actual gravitational force to the size of the observable universe. Although this can be realised...

Abstract: Recently, a qualitatively new class of rigorous bounds on CFT data was shown to be numerically computable from the crossing equations of six-point functions. However, this six-point bootstrap requires solving non-standard optimization...

Abstract: In a spacetime with asymptotically anti-de-Sitter boundaries, localized bulk events produce characteristic signals at boundary locations that are lightlike from the event. I will describe (thought) experiments that use boundary wavepackets...

Abstract: Motivated by Swampland conjectures, I will present a string theory inspired cosmological model with a coupled dark sector that evolves with a scalar field. When fitted to the recent DESI DR2 results (together with the CMB data and...

Abstract: Studying the Higgs boson and the mechanism of electroweak symmetry breaking remains one of the primary goals of current and future colliders, in the hope of resolving fundamental questions left unanswered in the Standard Model. A future...

Abstract: Quantum information science seeks to exploit the collective behavior of a large quantum system to enable tasks that are impossible (or less possible!) with classical resources alone. This burgeoning field encompasses a variety of...

Abstract: One-loop studies of de Sitter thermodynamics revealed universal codimension-2 “edge” degrees of freedom on the horizon of a static patch. I will show how to determine their spectra for fields of arbitrary mass and spin. For the graviton...

Abstract: The PADME experiment is a fixed-target high-energy physics setup located in Frascati, Italy, originally designed to search for dark photon production via collisions between a positron beam and a thin diamond target. In 2022, the experiment...
