Boundary conformal field theory and a boundary central charge [PDF]

Journal of High Energy Physics, 2017
We consider the structure of current and stress tensor two-point functions in conformal field theory with a boundary. The main result of this paper is a relation between a boundary central charge and the coefficient of a displacement operator correlation

Causal Boundary Entropy From Horizon Conformal Field Theory [PDF]

Physical Review Letters, 2000
The quantum theory of near horizon regions of spacetimes with classical spatially flat, homogeneous and isotropic Friedman-Robertson-Walker geometry can be approximately described by a two dimensional conformal field theory.

c=1 Boundary Conformal Field Theory Revisited [PDF]

Classical and Quantum Gravity, 2004
Correlation functions of discrete primary fields in the c=1 boundary conformal field theory of a scalar field in a critical periodic boundary potential are computed using the underlying SU(2) symmetry of the model.

Holographic boundary conformal field theory within Horndeski gravity

Journal of High Energy Physics
We investigate entanglement islands and the Page curve in the framework of Horndeski gravity on a Karch-Randall braneworld background. In particular, treating the holographic boundary conformal field theory analytically we find that the Horndeski ...

Exact C=1 Boundary Conformal Field Theories [PDF]

Physical Review Letters, 1993
We present a solution of the problem of a free massless scalar field on the half line interacting through a periodic potential on the boundary. For a critical value of the period, this system is a conformal field theory with a non-trivial and explicitly ...

Boundary Liouville conformal field theory in four dimensions

Journal of High Energy Physics
Higher dimensional Euclidean Liouville conformal field theories (LCFTs) consist of a log-correlated real scalar field with a background charge and an exponential potential. We analyse the LCFT on a four-dimensional manifold with a boundary.

An interacting, higher derivative, boundary conformal field theory

Journal of High Energy Physics
We consider a higher derivative scalar field theory in the presence of a boundary and a classically marginal interaction. We first investigate the free limit where the scalar obeys the square of the Klein-Gordon equation.

Boundary conformal fields and Tomita–Takesaki theory [PDF]

Journal of Mathematical Physics, 2003
Motivated by formal similarities between the continuum limit of the Ising model and the Unruh effect, this paper connects the notion of an Ishibashi state in boundary conformal field theory with the Tomita–Takesaki theory for operator algebras. A geometrical approach to the definition of Ishibashi states is presented, and it is shown that, when ...
