论文摘要
物质不同量子阶段之间的界面会引起新颖的物理学，例如外来拓扑阶段或非单身的保形场理论。在这里，我们研究了不同手性相的两个自旋链之间的界面。令人惊讶的是，这种相互作用的复合系统的平均场理论描述是根据弯曲的时空几何形状中的Dirac Fermions给出的。特别是，两个阶段之间的边界代表黑洞的地平线。我们证明，通过采用持续化来获得Luttinger液体模型，并通过使用矩阵产品状态方法来获得Luttinger液体模型，并通过数值来获取Luttinger液体模型。当两种相反的手势之间的淬灭，在界面的一侧淬灭时，出现了来自黑洞等效的惊人预测，这会导致另一侧随着鹰温度的温度而在广泛的参数和初始条件下进行热度。
The interface between different quantum phases of matter can give rise to novel physics, such as exotic topological phases or non-unitary conformal field theories. Here we investigate the interface between two spin chains in different chiral phases. Surprisingly, the mean-field theory description of this interacting composite system is given in terms of Dirac fermions in a curved space-time geometry. In particular, the boundary between the two phases represents a black hole horizon. We demonstrate that this representation is faithful both analytically, by employing bosonisation to obtain a Luttinger liquid model, and numerically, by employing Matrix Product State methods. A striking prediction from the black hole equivalence emerges when a quench, at one side of the interface between two opposite chiralities, causes the other side to thermalise with the Hawking temperature for a wide range of parameters and initial conditions.
