Entanglement under the renormalization-group transformations on quantum states and in quantum phase transitions
Tzu-Chieh Wei
We consider quantum states under the renormalization-group (RG) transformations introduced by Verstraete et al. [Phys. Rev. Lett. 94, 140601 (2005)] and propose a quantification of…

Relative entropy of entanglement for certain multipartite mixed states
Tzu-Chieh Wei
We prove conjectures on the relative entropy of entanglement (REE) for two families of multipartite qubit states. Thus, analytic expressions of REE for these families of states can…
