Luther-Emery liquid and dominant singlet superconductivity in the hole-doped Haldane spin-1 chain
Pontus Laurell, Jacek Herbrych, Gonzalo Alvarez +1
We investigate the pairing tendencies in the hole-doped Haldane spin-1 chain. To allow for doping, we extend the original spin chain Hamiltonian into a fermionic model involving a…
Spinon continuum in the Heisenberg quantum chain compound SrVO
Shang Gao, Ling-Fang Lin, Pontus Laurell +11
Magnetic excitations in the spin chain candidate SrVO have been investigated by inelastic neutron scattering on a single crystal sample. A spinon continuum with a bandw…
Reconstructing the spatial structure of quantum correlations in materials
Allen Scheie, Pontus Laurell, Elbio Dagotto +2
Quantum correlations are a fundamental property of quantum many-body states. Yet they remain experimentally elusive, hindering certification of genuine quantum behavior, especially…
