Entanglement susceptibilities and universal geometric entanglement entropy
William Witczak-Krempa
The entanglement entropy (EE) can measure the entanglement between a spatial subregion and its complement, which provides key information about quantum states. Here, rather than fo…

Entanglement signatures of emergent Dirac fermions: kagome spin liquid & quantum criticality
Wei Zhu, Xiao Chen, Yin-Chen He +1
Quantum spin liquids (QSL) are exotic phases of matter that host fractionalized excitations. It is difficult for local probes to characterize QSL, whereas quantum entanglement can…
