Non-Fermi liquid behavior in a simple model of Fermi arcs and pseudogap
Ruojun Wang, Kun Yang
We consider a perturbed version of a very simple and exactly solvable model that supports Fermi arcs and pseudogap in its ground state and excitation spectrum, which includes Hubba…

Dynamics of Quantum Hall Interfaces
Qi Li, Ken K. W. Ma, Ruojun Wang +3
A quantum Hall (QH) interface is different from an ordinary QH edge, as the latter has its location determined by the confining potential, while the former can be unpinned and beha…

Realization of supersymmetry and its spontaneous breaking in quantum Hall edges
Ken K. W. Ma, Ruojun Wang, Kun Yang
Supersymmetry (SUSY) relating bosons and fermions plays an important role in unifying different fundamental interactions in particle physics. Since no superpartners of elementary p…
