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…
Spin wave Hamiltonian and anomalous scattering in NiPS
A. Scheie, Pyeongjae Park, J. W. Villanova +8
We report a comprehensive spin wave analysis of the semiconducting honeycomb van der Waal antiferromagnet NiPS. Using single crystal inelastic neutron scattering, we map out th…
Multipartite entanglement in the 1-D spin- Heisenberg Antiferromagnet
Varun Menon, Nicholas E. Sherman, Maxime Dupont +3
Multipartite entanglement refers to the simultaneous entanglement between multiple subsystems of a many-body quantum system. While multipartite entanglement can be difficult to qua…
Dynamical fractal and anomalous noise in a clean magnetic crystal
Jonathan N. Hallén, Santiago A. Grigera, D. Alan Tennant +2
Fractals -- objects with non-integer dimensions -- occur in manifold settings and length scales in nature, ranging from snowflakes and lightning strikes to natural coastlines. Much…
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…
