Cluster Mean-Field Signature of Entanglement Entropy in Bosonic Superfluid-Insulator Transitions
Li Zhang, Xizhou Qin, Yongguan Ke +1
Entanglement entropy (EE), a fundamental conception in quantum information for characterizing entanglement, has been extensively employed to explore quantum phase transitions (QPTs…
