Emergent universality in critical quantum spin chains: entanglement Virasoro algebra
Qi Hu, Adrian Franco-Rubio, Guifre Vidal
Entanglement entropy and entanglement spectrum have been widely used to characterize quantum entanglement in extended many-body systems. Given a pure state of the system and a divi…
Note on anomalous currents for a free theory
Peng-Ju Hu, Qi-Lin Hu, Rong-Xin Miao
Recently it is found that, due to Weyl anomaly, an external magnetic field can induce anomalous currents near a boundary. In this note, we study anomalous currents for complex scal…
Continuous tensor network renormalization for quantum fields
Qi Hu, Adrian Franco-Rubio, Guifre Vidal
On the lattice, a renormalization group (RG) flow for two-dimensional partition functions expressed as a tensor network can be obtained using the tensor network renormalization (TN…
Scaling theory of entanglement entropy in confinements near quantum critical points
Xuanmin Cao, Qijun Hu, Fan Zhong
We propose a unified scaling theory of entanglement entropy in the confinements of finite bond dimensions, dynamics and system sizes. Within the theory, the finite-entanglement sca…
Scaling of the entanglement spectrum in driving critical dynamics
Qijun Hu, Shuai Yin, Fan Zhong
We present a scaling theory for the entanglement spectrum under an external driving. Based on the static scaling of the Schmidt gap and the theory of finite-time scaling, we show t…
