Superconductivity, pair density wave, and Neel order in cuprates
Li-Han Chen, Da Wang, Yi Zhou +1
We investigate in underdoped cuprates possible coexistence of the superconducting (SC) order at zero momentum and pair density wave (PDW) at momentum in the pres…

Matrix element interference in -patch functional renormalization group
Li-Han Chen, Zhen Liu, Jian-Ting Zheng
We show that the N-patch functional renormalization group (pFRG), a theoretical method commonly applied for correlated electron systems, is unable to implement consistently the mat…

Comment on "Unconventional Fermi Surface Instabilities in the Kagome Hubbard Model" by M. Kiesel, C. Platt, and R. Thomale, Phys. Rev. Lett. {\bf 110}, 126405 (2013)
Li-Han Chen, Zhen Liu, Jian-Ting Zheng
This is a comment on Phys. Rev. Lett. {\bf 110}, 126405 (2013), showing it biases the ferromagnetic order more than mean field theories would do. With over-biases like this, the th…
