Quantum brownian motion on a triangular lattice and c=2 boundary conformal field theory [PDF]
, 2001 We study a single particle diffusing on a triangular lattice and interacting with a heat bath, using boundary conformal field theory (CFT) and exact integrability techniques.

Boundary renormalization group flows in coset conformal field theories [PDF]
Phys.Rev. D67 (2003) 085001, 2003 We propose a new rule for boundary renormalization group flows in fixed-point free coset models. Our proposal generalizes the 'absorption of boundary spin'-principle formulated by Affleck and Ludwig to a large class of perturbations in boundary conformal field theories. We illustrate the rule in the case of unitary minimal models.

Fermion representation of the rolling tachyon boundary conformal field theory [PDF]
JHEP 0505:072,2005, 2005 A free fermion representation of the rolling tachyon boundary conformal field theory is constructed. The representation is used to obtain an explicit, compact, exact expression for the boundary state. We use the boundary state to compute the disc and cylinder amplitudes for the half-S-brane.

Some Issues in Conformal Field Theory with Boundaries and Crosscaps [PDF]
Int.J.Mod.Phys.A19S2:174-178,2004, 2002 This is a brief introduction to the subject of Conformal Field Theory on surfaces with boundaries and crosscaps, which describes the perturbative expansion of open string theory.

Integrable and Conformal Boundary Conditions for sl(2) A-D-E Lattice Models and Unitary Minimal Conformal Field Theories [PDF]
, 2001 Integrable boundary conditions are studied for critical A-D-E and general graph-based lattice models of statistical mechanics. In particular, using techniques associated with the Temperley-Lieb algebra and fusion, a set of boundary Boltzmann weights which satisfies the boundary Yang-Baxter equation is obtained for each boundary condition.

Coulomb-gas approach for boundary conformal field theory [PDF]
, 2002 We present a construction of boundary states based on the Coulomb-gas formalism of Dotsenko and Fateev. It is shown that Neumann-like coherent states on the charged bosonic Fock space provide a set of boundary states with consistent modular properties ...

Support of dS/CFT correspondence from perturbations of three dimensional spacetime [PDF]
, 2002 We discuss the relation between bulk de Sitter three-dimensional spacetime and the corresponding conformal field theory at the boundary, in the framework of the exact quasinormal mode spectrum.

Causal Boundary Entropy from Horizon Conformal Field Theory [PDF]
, 2001 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.

Bootstrapping boundary-localized interactions
Journal of High Energy Physics, 2020 We study conformal boundary conditions for the theory of a single real scalar to investigate whether the known Dirichlet and Neumann conditions are the only possibilities.
