Charge order and correlations in a clean overdoped cuprate superconductor

Recent RIXS studies on (Bi,Pb)2.12Sr1.88CuO6+δ (Bi2201) and La2-xSrxCuO4 (LSCO) have shown that charge order (CO) persists throughout the phase diagram of high temperature cuprate (HTC) superconductors and, in particular, through the overdoped region. The two compounds studied so far are relatively disordered and scattering is known to strongly suppress the transition temperature and superfluid density. Here propose to search for charge order and charge correlations in the overdoped region in the cleaner system Tl2Ba2CuO6+δ (Tl2201) which has a different Fermi surface topology to LSCO and reduced quasiparticle scattering. The results will shed light on the mechanism of charge ordering.
