Abstract: Abstract Recently, boundary conformal field theories (BCFTs) have attracted much attention in the context of quantum gravity. This is because a BCFT can be dual to gravity coupled to a heat bath CFT, known as… read more here.

Abstract: Abstract We study operators with large internal charge in boundary conformal field theories (BCFTs) with internal symmetries. Using the state-operator correspondence and the existence of a macroscopic limit, we find a non-trivial relation between the… read more here.

Abstract: We present a novel isogeometric method, namely the Immersed Boundary-Conformal Method (IBCM), that features a layer of discretization conformal to the boundary while employing a simple background mesh for the remaining domain. In this manner,… read more here.

Abstract: We numerically obtain the conformal spectrum of several classical spin models on a two-dimensional lattice with open boundaries, for each boundary fixed points obtained by the Cardy's derivation [J. L. Cardy, Nucl. Phys. B 324,… read more here.
