Connor Behan, Lorenzo Di Pietro, Edoardo Lauria, Balt C. van Rees

摘要:

我们提供了证据的存在性的非平凡的酉共形边界条件的三维自由标量场,这可以通过耦合到第m个酉对角线极小模型。对于大的m,我们可以证明存在的不动点扰动,并为较小的值,我们使用数值共形引导,以获得一个尖锐的扭结,顺利匹配到扰动预测。更广泛的数值分析也产生了任何其他边界条件的自由标量场的频谱的普遍范围。在这些边界的第二个扭结暗示在第二类非标准的边界条件,尚未确定。

英文摘要:

We provide evidence for the existence of non-trivial unitary conformal boundary conditions for a three-dimensional free scalar field, which can be obtained via a coupling to the m'th unitary diagonal minimal model. For large m we can demonstrate the existence of the fixed point perturbatively, and for smaller values we use the numerical conformal bootstrap to obtain a sharp kink that smoothly matches onto the perturbative predictions. The wider numerical analysis also yields universal bounds for the spectrum of any other boundary condition for the free scalar field. A second kink in these bounds hints at a second class of non-standard boundary conditions, as yet unidentified.
