Bogoliubov Quasiparticle on the Gossamer Fermi Surface in Electron-Doped Cuprates
Ke-Jun Xu, Qinda Guo, Makoto Hashimoto +14
In contrast to hole-doped cuprates, electron-doped cuprates consistently exhibit strong antiferromagnetic correlations with a commensurate (π, π) ordering wave vector, leading to t…
Emergent normal fluid in the superconducting ground state of overdoped cuprates
Shusen Ye, Miao Xu, Hongtao Yan +7
The microscopic mechanism for the disappearance of superconductivity in overdoped cuprates is still under heated debate. Here we use scanning tunneling spectroscopy to investigate…
Superconducting valence bond fluid in lightly doped 8-leg - cylinders
Hong-Chen Jiang, Steven A. Kivelson, Dung-Hai Lee
Superconductivity in doped quantum paramagnets has been a subject of long theoretical inquiry. In this work we report a density matrix renormalization group study of lightly doped…
Non-abelian bosonization of fermion symmetry-protected topological states
Yen-Ta Huang, Dung-Hai Lee
Applying the results of Ref.[1], we carry out the non-abelian bosonization for a class of free fermion symmetry-protected topological states (SPTs). The resulting boson theories ar…
The electromagnetic duality and the 3+1D O(6) non-linear sigma model with a level-1 Wess-Zumino-Witten term
Yen-Ta Huang, Dung-Hai Lee
We show that in (3+1)-D space-time dimensions, the O(6) non-linear sigma model, with a level-1 Wess-Zumino-Witten term, exhibits the electromagnetic duality. If we name the six com…
Competing orders, the Wess-Zumino-Witten term, and spin liquids
Yen-Ta Huang, Dung-Hai Lee
In this paper, we demonstrate that in frustrated magnets when several conventional (i.e., symmetry-breaking) orders compete, and are "intertwined" by a Wess-Zumino-Witten (WZW) ter…
