Doping-dependent precursor charge density wave correlations in La2-xBaxCuO4
ORAL
Abstract
Recently using resonant inelastic x-ray scattering (RIXS), we discovered, in La2-xBaxCuO4 x=0.125, precursor charge density wave (CDW) correlations that exist above the CDW transition temperature and observed that its wavevector varies with temperature and becomes unlocked from the spin wavevector [1]. This observation may help to reconcile the distinct doping-dependence of CDW wavevector in different cuprates families [1,2]. Here we show our new RIXS study that reveals the doping-dependent evolution of precursor CDW in La2-xBaxCuO4.
