Fractional Mutual Statistics on Integer Quantum Hall Edges
June-Young M. Lee, Cheolhee Han, H. -S. Sim
Fractional charge and statistics are hallmarks of low-dimensional interacting systems such as fractional quantum Hall (QH) systems. Integer QH systems are regarded noninteracting,…
Symmetric inseparability and number entanglement in charge conserving mixed states
Zhanyu Ma, Cheolhee Han, Yigal Meir +1
We explore sufficient conditions for inseparability in mixed states with a globally conserved charge, such as a particle number. We argue that even separable states may contain ent…
Multi-impurity chiral Kondo model: correlation functions and anyon fusion rules
Dor Gabay, Cheolhee Han, Pedro L. S. Lopes +2
The multichannel Kondo model supports effective anyons on the partially screened impurity, as suggested by its fractional impurity entropy. It was recently demonstrated for the mul…
Fractional entropy of multichannel Kondo systems from conductance-charge relations
Cheolhee Han, Zubair Iftikhar, Yaakov Kleeorin +5
Fractional entropy is a signature of nonlocal degrees of freedom, such as Majorana zero modes or more exotic non-Abelian anyons. Although direct experimental measurements remain ch…
