Exciton condensation of composite fermions in double layer quantum Hall systems
Xiang-Jian Hou, Lei Wang, Ying-Hai Wu
We study fractional quantum Hall states in double layer systems that can be interpreted as exciton condensates of composite fermions. An electron in one layer is dressed by two flu…
Non-Abelian interlayer coherent fractional quantum Hall states
Xiang-Jian Hou, Lei Wang, Ying-Hai Wu
We study non-Abelian fractional quantum Hall state in double layer systems at total filling factor . Recent progresses in two-dimensional van der Waals materials made it possi…
Bridging conformal field theory and parton approaches to SU(n)_k chiral spin liquids
Tong Liu, Ying-Hai Wu, Hong-Hao Tu +1
We employ the Wess-Zumino-Witten (WZW) model in conformal field theory to construct lattice wave functions in both one and two dimensions. The spins on all latti…
Crosscap states and duality of Ising field theory in two dimensions
Yueshui Zhang, Ying-Hai Wu, Lei Wang +1
We propose two distinct crosscap states for the two-dimensional (2D) Ising field theory. These two crosscap states, identifying Ising spins or dual spins (domain walls) at antipoda…
