Boundary Entropy Can Increase Under Bulk RG Flow [PDF]

, 2007
The boundary entropy log(g) of a critical one-dimensional quantum system (or two-dimensional conformal field theory) is known to decrease under renormalization group (RG) flow of the boundary theory.

Boundary Liouville Field Theory: Boundary Three Point Function [PDF]

Nucl.Phys.B622:309-327,2002, 2001
Liouville field theory is considered on domains with conformally invariant boundary conditions. We present an explicit expression for the three point function of boundary fields in terms of the fusion coefficients which determine the monodromy properties of the conformal blocks.

Composite operators near the boundary

Journal of High Energy Physics, 2020
We use renormalization group methods to study composite operators existing at a boundary of an interacting conformal field theory. In particular we relate the data on boundary operators to short-distance (near-boundary) divergences of bulk two-point ...

Exact Solutions in SFT and Marginal Deformation in BCFT

, 2003
In this note we will study solution of open bosonic string field theory based on action of operators from chiral algebra of boundary conformal field theory on identity element of string field theory star algebra. We will demonstrate that the string field

On analytic bootstrap for interface and boundary CFT

Journal of High Energy Physics, 2021
We use analytic bootstrap techniques for a CFT with an interface or a boundary. Exploiting the analytic structure of the bulk and boundary conformal blocks we extract the CFT data.

Gravitational Perturbation and Kerr/CFT Correspondence

, 2015
We find the explicit form of two-point function for the conformal spin-2 energy momentum operators on the near horizon of a near extremal Kerr black hole by variation of a proper boundary action. In this regard, we consider an appropriate boundary action

Entanglement properties of boundary state and thermalization

Journal of High Energy Physics, 2018
We discuss the regularized boundary state e−τ0H|Ba $$ {e}^{-{\tau}_0H}\Big|{\left.B\right\rangle}_a $$ on two aspects in both 2D CFT and higher dimensional free field theory.

Fermionic CFTs and classifying algebras

Journal of High Energy Physics, 2020
We study fermionic conformal field theories on surfaces with spin structure in the presence of boundaries, defects, and interfaces. We obtain the relevant crossing relations, taking particular care with parity signs and signs arising from the change of ...

A Note on Einstein Gravity on AdS$_3$ and Boundary Conformal Field Theory [PDF]

, 1998
We find a simple relation between the first subleading terms in the asymptotic expansion of the metric field in AdS$_3$, obeying the Brown-Henneaux boundary conditions, and the stress tensor of the underlying Liouville theory on the boundary. We can also

Is boundary conformal in CFT? [PDF]

, 2012
We discuss boundary conditions for conformal field theories that preserve the boundary Poincare invariance. As in the bulk field theories, a question arises whether boundary scale invariance leads to boundary conformal invariance. With unitarity, Cardy's condition of vanishing momentum flow is necessary for the boundary conformal invariance, but it is ...
