Low-energy collective dynamics of charge stripes in the doped nickelate La2-xSrxNiO4+delta observed with optical conductivity measurements
We have investigated charge dynamics in the static stripe ordered phase of La2-x Srx Ni O4+δ at lattice temperatures below the charge ordering transition, via optical conductivity measurements at low energies (1-10 meV). The thermally activated dynamic response of the charge stripes is found to be c...
