Abstract: For Pauli stabilizer codes—such as surface codes and color codes—transversal logical gates are strongly constrained by the Bravyi–König bound. In particular, implementing a non-Clifford gate transversally (as required for universality)...

Abstract: In this talk, I will discuss Cosmohedra. These are geometric objects which encode the vacuum wavefunction for theories with colored scalars with cubic interactions. I will start by introducing the vacuum wavefunction, both in Minkowski and...

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 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: I will explain how the irreversibility of the renormalization group together with anomalies, including anomalies in the space of coupling constants, can be used to constrain the IR phases of defects in familiar quantum field theories. As...

Abstract: Drawing inspiration from AdS/CFT holography, I will discuss the idea that a static patch in de Sitter space admits a fundamental description based upon standard quantum mechanics. Taking a bottom-up perspective, I compute correlation...

Abstract: Black hole perturbation theory captures a few important effects in the dynamics of binary mergers, such as tidal deformations and the decay of ringdown modes. It also describes the physics of the photon ring. However, extracting...

Abstract: Mostly concerning Lorentz-invariance and the matrix-approximation of membranes ( GH1982: http:/dspace.mit.edu/handle/1721.1/15717, G1985, BFFS1997: Phys.Rev.D 55, 5512 ), as well as non-commutative string-theory ( JH1996: hep-th/9602020...

Abstract: Quantum condensed matter has traditionally focused on ground states and equilibrium properties of spatially extended systems, such as electrons in crystalline materials. However, the advent of noisy-intermediate-scale-quantum (NISQ)...

Abstract: Despite the undeniable success of the Large Hadron Collider (LHC), Beyond the Standard Model (BSM) physics remains elusive. In this talk, I will outline a multifaceted strategy to maximize discovery potential at current and future high...
