Abstract: I discuss physical motivations from black hole physics and holography for expecting finite quantum entanglement entropy in quantum gravity. I describe recent and earlier results in defining such a notion in perturbative string theory by a...

Abstract: Gravitational wave and electromagnetic observations of strongly gravitating systems allow us not only to probe black holes and neutron stars, but also have the potential to uncover new fundamental physics. Superradiant bosonic clouds and...

Abstract: In this talk, I will introduce a new framework of quantum convolution to study stabilizer states and magic states in discrete-variable systems. Within this convolutional framework, we find that the stabilizer states play a similar role to...

Abstract: The moduli space of curves, M_g, is an object of pivotal interest in mathematics and theoretical physics. Even though it has been studied with tremendous effort, little is known about its topology. For instance, the total dimension of the...

Abstract: Both physics and neuroscience seek to understand how the edges and nodes of a network dictate its function. But until recently, it was not possible to quantitatively explore the relation between the structure and function of a biological...

Abstract: I will briefly review the factorisation of soft and collinear singularities in massless gauge theory amplitudes, and the structure of the soft anomalous dimension matrix. I will then discuss the implications of this factorisation for the...

Abstract: The spectrum of single-trace operators of order-one dimension, of holographic CFTs at strong coupling and large N, can be mapped to the spectrum of Kaluza-Klein (KK) excitations over the dual AdS supergravity solutions. Computing these KK...

Dark matter interactions with Standard Model particles can inject energy at early times, altering the standard evolution of the early universe. In particular, this energy injection can perturb the spectrum of the cosmic microwave background (CMB)...

Abstract: The density of states of a unitary conformal field theory is known to have a universal behavior at high energy. In two dimensions, this behavior is described by the Cardy formula. If the theory has symmetry, it is interesting to understand...
