Scaling of entanglement entropy across Lifshitz transitions
Marlon Rodney, H. Francis Song, Sung-Sik Lee +2
We investigate the scaling of the bipartite entanglement entropy across Lifshitz quantum phase transitions, where the topology of the Fermi surface changes without any changes in s…

Fractionalized topological insulators from frustrated spin models in three dimensions
Subhro Bhattacharjee, Yong Baek Kim, Sung-Sik Lee +1
We present a theory of three dimensional fractionalized topological insulators in the form of U(1) spin liquids with gapped fermionic spinons in the bulk and topologically protecte…
