Quantifying and controlling entanglement in the quantum magnet CsCoCl
Pontus Laurell, Allen Scheie, Chiron J. Mukherjee +7
The lack of methods to experimentally detect and quantify entanglement in quantum matter impedes our ability to identify materials hosting highly entangled phases, such as quantum…
Early experimental evidence of a topological quantum state: The signature of the Haldane ground state revealed by scattered neutrons
M. Enderle, M. Kenzelmann, W. J. L. Buyers
Neutron scattering played an important role in the experimental exploration of the theoretical ideas of Thouless, Haldane, and Kosterlitz, who won the Nobel Prize in Physics in 201…
Fractional excitations in the square-lattice quantum antiferromagnet
B. Dalla Piazza, M. Mourigal, N. B. Christensen +7
The square-lattice quantum Heisenberg antiferromagnet displays a pronounced anomaly of unknown origin in its magnetic excitation spectrum. The anomaly manifests itself only for sho…
Quantum dynamics and entanglement of spins on a square lattice
N. B. Christensen, H. M. Ronnow, D. F. McMorrow +6
Bulk magnetism in solids is fundamentally quantum mechanical in nature. Yet in many situations, including our everyday encounters with magnetic materials, quantum effects are maske…
Magnetic-field-induced spin excitations and renormalized spin gap of the underdoped superconductor LaSrCuO
J. Chang, A. P. Schnyder, R. Gilardi +15
High-resolution neutron inelastic scattering experiments in applied magnetic fields have been performed on LaSrCuO (LSCO). In zero field, the temperature…
Evolution of spin excitations in a gapped antiferromagnet from the quantum to the high-temperature limit
M. Kenzelmann, R. A. Cowley, W. J. L. Buyers +3
We have mapped from the quantum to the classical limit the spin excitation spectrum of the antiferromagnetic spin-1 Heisenberg chain system CsNiCl3 in its paramagnetic phase from T…
