Spin singlet topological superconductivity in the attractive Rashba Hubbard model
Peter Doak, Giovanni Balduzzi, Pontus Laurell +2
Fully gapped, spin singlet superconductors with antisymmetric spin-orbit coupling in a Zeeman magnetic field provide a promising route to realize superconducting states with non-Ab…
Spin dynamics of the generalized quantum spin compass chain
Pontus Laurell, Gonzalo Alvarez, Elbio Dagotto
We calculate the dynamical spin structure factor of the generalized spin- compass spin chain using the density matrix renormalization group. The model, also known as the twist…
Spin sensitive transport in RuCl_3/Pt heterostructures: revealing a field-transverse spin anisotropy in a spin liquid candidate
H. Idzuchi, M. Kimata, S. Okamoto +7
Alpha-phase (a-) RuCl_3 has emerged as a possible candidate for a quantum spin liquid (QSL) that promises exotic quasi-particles relevant for fault-tolerant quantum computation. He…
Magnetic excitations, non-classicality and quantum wake spin dynamics in the Hubbard chain
Pontus Laurell, Allen Scheie, D. Alan Tennant +3
Recent work has demonstrated that quantum Fisher information (QFI), a witness of multipartite entanglement, and magnetic Van Hove correlations , a probe of local real-space…
Extraction of the interaction parameters for RuCl from neutron data using machine learning
Anjana M. Samarakoon, Pontus Laurell, Christian Balz +6
Single crystal inelastic neutron scattering data contain rich information about the structure and dynamics of a material. Yet the challenge of matching sophisticated theoretical mo…
Quantum wake dynamics in Heisenberg antiferromagnetic chains
Allen Scheie, Pontus Laurell, Bella Lake +4
Traditional spectroscopy, by its very nature, characterizes properties of physical systems in the momentum and frequency domains. The most interesting and potentially practically u…
