论文摘要
我们讨论在环境重新归一化组流动下边界熵的变化。我们使用共形扰动理论来计算附近两个固定点之间的边界熵的变化。我们还使用AD $ _ {D+1} $/BCFT $ _D $模型来计算边界熵。我们表明,在整形扰动理论和ADS $ _ {D+1} $/BCFT $ _D $模型中,边界熵都可以在环境RG流下增加。在特殊情况下,广告$ _ {d+1} $/bcft $ _d $模型中边界熵的变化减少了共形扰动理论。
We discuss the change of the boundary entropy under an ambient renormalization group flow. We use conformal perturbation theory to calculate the change of the boundary entropy for $d$-dimensional BCFTs between two nearby fixed points. We also use the AdS$_{d+1}$/BCFT$_d$ model to calculate the boundary entropy. We show that the boundary entropy can increase under the ambient RG flow both in conformal perturbation theory and the AdS$_{d+1}$/BCFT$_d$ model. In a special case, the change of the boundary entropy in the AdS$_{d+1}$/BCFT$_d$ model reduces to that of the conformal perturbation theory.
