Entanglement entropy plays a variety of roles in quantum field theory, including the
connections between quantum states and gravitation through the holographic principle. This …

In this review article, we discuss the distinction and possible equivalence between scale
invariance and conformal invariance in relativistic quantum field theories. Under some …

A bstract Recent progress in our understanding of the black hole information paradox has
lead to a new prescription for calculating entanglement entropies, which involves special …

A bstract Motivated by recent studies of holographic complexity, we examine the question of
circuit complexity in quantum field theory. We provide a quantum circuit model for the …

A bstract We use holography to study sensitive dependence on initial conditions in strongly
coupled field theories. Specifically, we mildly perturb a thermofield double state by adding a …

A bstract Setting the cosmological constant to be dynamical, we study the bulk and boundary
thermodynamics of charged Anti-de Sitter black holes. We develop mass/energy formulas in …

The 3D Ising transition, the most celebrated and unsolved critical phenomenon in nature,
has long been conjectured to have emergent conformal symmetry, similar to the case of the …

We consider line defects in d-dimensional conformal field theories (CFTs). The ambient CFT
places nontrivial constraints on renormalization group (RG) flows on such line defects. We …

A bstract We examine holographic complexity in the doubly holographic model introduced in
[1, 2] to study quantum extremal islands. We focus on the holographic complexity= volume …

A bstract Entanglement entropy obeys a 'first law', an exact quantum generalization of the
ordinary first law of thermodynamics. In any CFT with a semiclassical holographic dual, this …
