Exploring the holographic entropy cone via reinforcement learning
Temple He, Jaeha Lee, Hirosi Ooguri
We develop a reinforcement learning algorithm to study the holographic entropy cone. Given a target entropy vector, our algorithm searches for a graph realization whose min-cut ent…
Continuous Family of Conformal Field Theories and Exactly Marginal Operators
Shota Komatsu, Yuya Kusuki, Marco Meineri +1
Does a conformal manifold imply the existence of exactly marginal operators? We answer this question affirmatively under the assumption that there exists a conformal interface with…
Universality of Rényi Entropy in Conformal Field Theory
Yuya Kusuki, Hirosi Ooguri, Sridip Pal
We use the thermal effective theory to prove that, for the vacuum state in any conformal field theory in dimensions, the -th Rényi entropy behaves as $S_A^{(n)}…
Nonrenormalization Theorem for Interface Entropy
Andreas Karch, Hirosi Ooguri, Mianqi Wang
We derive a formula for the half-BPS interface entropy between any pair of theories on the same conformal manifold. This generalizes the diastasis formula derived…
Entanglement asymmetry and symmetry defects in boundary conformal field theory
Yuya Kusuki, Sara Murciano, Hirosi Ooguri +1
A state in a quantum system with a given global symmetry, , can be sensitive to the presence of boundaries, which may either preserve or break this symmetry. In this work, we in…
