Anisotropy of incommensurate spin and charge fluctuations in detwinned YBa${}_2$Cu${}_3$O${}_{6+\delta }$

T. Zhou, Jian-Xin Li

Motivated by a recent neutron scattering experiment on detwinned YBa${}_2$Cu${}_3$O${}_{6+\delta }$ superconductor, we examine the frequency and doping dependence of the anisotropy in the spin…
