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 in quantum magnets using neutron scattering
A. Scheie, Pontus Laurell, A. M. Samarakoon +6
We demonstrate how quantum entanglement can be directly witnessed in the quasi-1D Heisenberg antiferromagnet KCuF. We apply three entanglement witnesses --- one-tangle, two-tan…
Detection of Kardar-Parisi-Zhang hydrodynamics in a quantum Heisenberg spin- chain
A. Scheie, N. E. Sherman, M. Dupont +5
Classical hydrodynamics is a remarkably versatile description of the coarse-grained behavior of many-particle systems once local equilibrium has been established. The form of the h…
PyCrystalField: Software for Calculation, Analysis, and Fitting of Crystal Electric Field Hamiltonians
Allen Scheie
We introduce PyCrystalField, a Python software package for calculating single-ion crystal electric field (CEF) Hamiltonians. This software can calculate a CEF Hamiltonian \textit{a…
