Nearly degenerate ground states of a checkerboard antiferromagnet and their bosonic interpretation
Haiyuan Zou, Fan Yang, Wei Ku
The spin- model system with antiferromagnetic (AF) couplings on a - checkerboard lattice, known as the planar pyrochlore model, is strongly frustrated and associated…

Frustrated superconductivity and sextetting order
Zhiming Pan, Chen Lu, Fan Yang +1
The superconducting state typically favors a uniform spatial distribution akin to ferromagnetism. Nevertheless, the pair-density-wave state exhibits sign changes in the pairing ord…
