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...

Abstract: I discuss a holographic duality between the SYK model in a double scaling limit and a 2d theory of quantum cosmology called sine dilaton gravity.

Abstract: I will explore one of the most profound open question in particle physics, focusing on some exciting directions of my ongoing research activity: the strong CP problem. I will begin with an overview of the strong CP problem, highlighting...

Abstract: Global symmetry and anomaly have long served as powerful organizing principles for understanding quantum phases of matter in ground states. In this talk I will discuss recent progress in extending these ideas to many-body mixed states. I...
