We calculate logarithmic negativity, a quantum entanglement measure for mixed quantum
states, in quantum error-correcting codes and find it to equal the minimal cross sectional …

A remarkable yet mysterious property of black holes is that their entropy is proportional to the
horizon area. This area law inspired the holographic principle, which was later realized …

A bstract We prove a conjectured lower bound on< T__ (x)> ψ in any state ψ of a CFT on
Minkowski space, dubbed the Quantum Null Energy Condition (QNEC). The bound is given …

A bstract We use the numerical bootstrap to study conformal line defects with O (2) global
symmetry. Our results are very general and capture in particular conformal line defects …

A bstract Recently, a codimension two holography called wedge holography is proposed as
a generalization of AdS/CFT. It is conjectured that a gravitational theory in d+ 1 dimensional …

A bstract We study the constraints of superconformal symmetry on codimension two defects
in four-dimensional superconformal field theories. We show that the one-point function of the …

A bstract We study the spectrum of local operators living on a defect in a generic conformal
field theory, and their coupling to the local bulk operators. We establish the existence of …

A bstract We study monodromy defects in O (N) symmetric scalar field theories in d
dimensions. After a Weyl transformation, a monodromy defect may be described by placing …

We present a summary of recent progress and remaining challenges in applying the
methods and ideas of quantum information theory to the study of quantum field theory and …

A bstract We study co-dimension two monodromy defects in theories of conformally coupled
scalars and free Dirac fermions in arbitrary d dimensions. We characterise this family of …
