Quantum Geometry in the Lab

Standard particle theory is based on quantized matter embedded in a classical geometry. Here, a complementary model is proposed, based on classical matter -- massive bodies, without quantum properties -- embedded in a quantum geometry. It does not describe elementary particles, but may be a better, fully consistent quantum description for position states in laboratory-scale systems. Gravitational theory suggests that the geometrical quantum system has an information density of about one qubit per Planck length squared. If so, the model here predicts that the quantum uncertainty of geometry creates a new form of noise in the position of massive bodies, detectable by interferometers.

Spin observables in charged pion photo-production from polarized neutrons in solid HD at Jefferson Lab

E asymmetries have been extracted from double-polarizationexperiments in Hall-B of the Thomas Jefferson National Accelerator Facility (JLab). Results have been obtained from the E06-101 (g14) experiment, using circularly polarized photon beams, longitudinally polarized Deuterons in solid HD targets, and the CEBAF Large Acceptance Spectrometer (CLAS). The results cover a range inW from 1.48 to 2.32 GeV. Three independent analyses, using distinctly different methods, have been combined to obtain the final values, which have been published recently. Partial wave analyses (PWA), which have had to rely on a sparse neutron data base, havebeen significantly changed with the inclusion of these g14 asymmetries.

National labs examine effects of new fuels on current equipment

Here, studies at two national laboratories show that using existing transportation fuel infrastructure and systems designed for use and compatibility with gasoline and E10 at gas stations likely will create compatibility issues when used with new fuel chemistries. For more than 10 years, The National Renewable Energy Laboratory (NREL) in Golden, Colorado, and Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee, have been evaluating what happens when new fuels come into contact with the current storage and dispensing systems.
