A general track reconstruction scheme and its application to the OPERA drift tubes
A general reconstruction and calibration procedure for tracking and wire
position determination of the OPERA drift tubes is presented. The mathematics
of the pattern recognition and the track fit are explained.Comment: 19 page
Quantum discord and quantum phase transition in spin chains
Quantum phase transitions of the transverse Ising and antiferromagnetic XXZ
spin S=1/2 chains are studied using quantum discord. Quantum discord allows the
measure of quantum correlations present in many-body quantum systems. It is
shown that the amount of quantum correlations increases close to the critical
points. The observations are in agreement with the information provided by the
concurrence which measures the entanglement of the many-body system.Comment: 8 pages, 9 figure
Mind-Body Interpretation of Quantum Mechanics
The wave-particle duality is a mind-body one. In the real 3D-space there
exists only the particle, the wave exists in its consciousness. If there are
many particles, their distribution in accordance with the wave function
represents a real wave in real space. Many worlds, Schroedinger cat, etc.,
exist only as mental constructions. The "waves of matter" are non-material.
Feynman et al. taught quantum world "is like neither". Alas, they forgot living
matter.Comment: 7 pages including 5 figures and 6 references. The shortened version
