Frame representations of quantum mechanics and the necessity of negativity in quasi-probability representations
Christopher Ferrie, Joseph Emerson
Several finite dimensional quasi-probability representations of quantum states have been proposed to study various problems in quantum information theory and quantum foundations. T…
Quantum-Classical Correspondence for the Equilibrium Distributions of Two Interacting Spins
J. Emerson, L. E. Ballentine
We consider the quantum and classical Liouville dynamics of a non-integrable model of two coupled spins. Initially localised quantum states spread exponentially to the system dimen…
Characteristics of Quantum-Classical Correspondence for Two Interacting Spins
J. Emerson, L. E. Ballentine
The conditions of quantum-classical correspondence for a system of two interacting spins are investigated. Differences between quantum expectation values and classical Liouville av…
Measurement of the Neutron Spin Structure Function with a Polarized ^3He Target
The HERMES Collaboration, K. Ackerstaff
Results are reported from the HERMES experiment at HERA on a measurement of the neutron spin structure function in deep inelastic scattering using 27.5 GeV longitudi…
