Nonlinear light cone spreading of correlations in a triangular quantum magnet: a hard quantum simulation target
A. Scheie, J. Willsher, E. A. Ghioldi +6
Dynamical correlations of quantum many-body systems are typically analyzed in the momentum space and frequency basis. However, quantum simulators operate more naturally in real spa…
Intrinsic quantum disorder in Yb2Ti2O7 and the quantum S=1/2 pyrochlore phase diagram
Shang-Shun Zhang, Anish Bhardwaj, S. M. Koohpayeh +4
We present an experimental and theoretical study of the anisotropic pyrochlore phase diagram. Inelastic field-dependent neutron scattering on YbTiO shows intrinsic broa…
Tutorial: Extracting entanglement signatures from neutron spectroscopy
Allen Scheie, Pontus Laurell, Wolfgang Simeth +2
This tutorial is a pedagogical introduction to recent methods of computing quantum spin entanglement witnesses from spectroscopy, with a special focus on neutron scattering on quan…
Witnessing Entanglement and Quantum Correlations in Condensed Matter: A Review
Pontus Laurell, Allen Scheie, Elbio Dagotto +1
The detection and certification of entanglement and quantum correlations in materials is of fundamental and far-reaching importance, and has seen significant recent progress. It im…
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…
