Non-equilibrium dynamics of spin-lattice coupling
Hiroki Ueda, Roman Mankowsky, Eugenio Paris +18
Interactions between the different degrees of freedom form the basis of many manifestations of intriguing physics in condensed matter. In this respect, quantifying the dynamics of…
Collective nature of orbital excitations in layered cuprates in the absence of apical oxygens
Leonardo Martinelli, Krzysztof Wohlfeld, Jonathan Pelliciari +19
We have investigated the 3d orbital excitations in CaCuO2 (CCO), Nd2CuO4 (NCO), and La2CuO4 (LCO) using high-resolution resonant inelastic x-ray scattering. In LCO they behave as w…
Unravelling the Nature of Spin Excitations Disentangled from Charge Contributions in a Doped Cuprate Superconductor
Wenliang Zhang, Cliò Efthimia Agrapidis, Yi Tseng +7
The nature of the spin excitations in superconducting cuprates is a key question toward a unified understanding of the cuprate physics from long-range antiferromagnetism to superco…
Terahertz displacive excitation of a coherent Raman-active phonon in VO
Flavio Giorgianni, Mattia Udina, Tommaso Cea +7
Nonlinear processes involving frequency-mixing of light fields set the basis for ultrafast coherent spectroscopy of collective modes in solids. In certain semimetals and semiconduc…
Crossover of the high-energy spin fluctuations from collective triplons to localized magnetic excitations in doped Sr14-xCaxCu24O41 cuprate ladders
Y. Tseng, J. Thomas, W. Zhang +13
We studied the magnetic excitations in the quasi-one-dimensional (q-1D) ladder subsystem of Sr_(14-x) Ca_x Cu_24 O_41(SCCO) using Cu L_3-edge resonant inelastic X-ray scattering (R…
Resonant Inelastic X-ray Scattering Study of Electron-Exciton Coupling in High-Tc Cuprates
F. Barantani, M. K. Tran, I. Madan +14
Explaining the mechanism of superconductivity in the high- cuprates requires an understanding of what causes electrons to form Cooper pairs. Pairing can be mediated by phonons…
