We propose a real-space renormalization group method to explicitly decouple into independent components a many-body system that, as in the phenomenon of spin-charge separation, exhibits separation of degrees of freedom at low energies. Our approach produces a branching holographic description of such systems that opens the path to the efficient simulation of the most entangled phases of quantum matter, such as those whose ground state violates a boundary law for entanglement entropy.

我们提出了一种实空间重整化群方法，以将表现出低能自由度分离的多体系统（如自旋电荷分离现象）显式地分解为独立的分量。我们的方法为这样的系统产生了一个分支全息描述，为有效模拟量子物质的最纠缠相开辟了道路，例如那些其基态违反纠缠熵边界定律的物质。就像 Vidal 的粗粒化变换一样[Phys. Rev. Lett. 99, 220405 (2007).
