The Halogenation of Aromatic Carbinols

In recent years many efforts have been made aiming to define the conditions of the reaction of substitution which lead to inversion of configuration (Walden inversion). The investigations in this direction of Polanyi et al.,’ of Olson,2 of Hughes, Ingold, et aL3 are most outstanding. Polanyi et al. and Olson came to the conclusion that all reactions of substitution by a negative group or ion ar...

9 v 3 1 5 N ov 1 99 9 Fisher information in quantum statistics

Braunstein and Caves (1994) proposed to use Helstrom’s quantum information number to define, meaningfully, a metric on the set of all possible states of a given quantum system. They showed that the quantum information is nothing else than the maximal Fisher information in a measurement of the quantum system, maximized over all possible measurements. Combining this fact with classical statistica...

9 v 1 9 A ug 1 99 5 NONLOCALITY AS AN AXIOM FOR QUANTUM THEORY

Quantum mechanics and relativistic causality together imply nonlocality: nonlo-cal correlations (that violate the CHSH inequality) and nonlocal equations of motion (the Aharonov-Bohm effect). Can we invert the logical order? We consider a conjecture that nonlocality and relativistic causality together imply quantum mechanics. We show that correlations preserving relativistic causality can viola...

9 v 1 2 5 A pr 1 99 5 Results from the LSND Neutrino Oscillation

The Liquid Scintillator Neutrino Detector (LSND) at the Los Alamos Meson Physics Facility sets bounds on neutrino oscillations in the appearance channel νμ → νe by searching for the signature of the reaction νep → e +n : an e+ followed by a 2.2MeV gamma ray from neutron capture. Five e–γ coincidences are observed in time with the LAMPF beam, with an estimated background of 6.2 events. The 90% c...
