The nature of effective interaction in cuprate superconductors: a sign-problem-free quantum Monte-Carlo study
Zi-Xiang Li, Fa Wang, Hong Yao +1
Superconductivity is an emergent phenomena in the sense that the energy scale associated with Cooper pairing is generically much lower than the typical kinetic energy of electrons.…
Fermion-induced quantum critical points
Zi-Xiang Li, Yi-Fan Jiang, Shao-Kai Jian +1
A unified theory of quantum critical points beyond the conventional Landau-Ginzburg-Wilson paradigm remains unknown. According to Landau cubic criterion, phase transitions should b…
What makes the Tc of monolayer FeSe on SrTiO3 so high: a sign-problem-free quantum Monte Carlo study
Zi-Xiang Li, Fa Wang, Hong Yao +1
Monolayer FeSe films grown on SrTiO3 (STO) substrate show superconducting gap-opening temperatures (Tc) which are almost an order of magnitude higher than those of the bulk FeSe an…
Visualizing the elongated vortices in -Ga nanostrips
Hui-Min Zhang, Zi-Xiang Li, Jun-Ping Peng +10
We study the magnetic response of superconducting -Ga via low temperature scanning tunneling microscopy and spectroscopy. The magnetic vortex cores rely substantially on the Ga…
