Charge-orbital-lattice coupling effects in the dd-excitation profile of one dimensional cuprates

J. J. Lee, B. Moritz, W. S. Lee +12

We identify dd-excitations in the quasi-one dimensional compound Ca${}_2$Y${}_2$Cu${}_5$O${}_{10}$ using resonant inelastic x-ray scattering. By tuning across the Cu L${}_3$-edge, we observe…
