ABSTRACT
The development of qualitatively new measurement capabilities is often a prerequisite for critical scientific and technological advances. Here we introduce an unconventional quantum probe, an entangled neutron beam, where individual neutrons can be entangled in spin, trajectory and energy. The spatial separation of trajectories from nanometers to microns and energy differences from peV to neV will enable investigations of microscopic magnetic correlations in systems with strongly entangled phases, such as those believed to emerge in unconventional superconductors. We develop an interferometer to prove entanglement of these distinguishable properties of the neutron beam by observing clear violations of both Clauser-Horne-Shimony-Holt and Mermin contextuality inequalities in the same experimental setup. Our work opens a pathway to a future of entangled neutron scattering in matter.
ABSTRACT
Of 200 consecutively admitted leg fracture patients, 101 consented to be screened for psychopathology using the BSI and SMAST questionnaires. Probable cases of psychopathology were referred for diagnostic psychiatric evaluation. Of the participants, 80.2 percent were identified as possible psychiatric cases. Diagnostic evaluation revealed high prevalence of substance abuse (66.0%), depression (46.8%), and personality pathology (38.3%). Accident victims tended to be single young males. Accidents occurred mostly during leisure hours, and were often associated with alcohol use. Psychiatric assistance appears essential in the management of such patients. Psychiatrists need to be especially knowledgeable about chemical dependency, interpersonal issues and psychotherapy.
