A class of entanglement monotones for general pure multipartite states based on complex projective variety
Hoshang Heydari
We construct a measure of entanglement for general pure multipartite states based on Segre variety. We also construct a class of entanglement monotones based on the Plücker coordin…
Charge quantization conditions based on the Atiyah--Singer index theorem
Shinichi Deguchi, Kaoru Kitsukawa
Dirac's quantization condition, (), and Schwinger's quantization condition, (), for an electric charge and a magnetic charge are…
The ~U(12)-Classification Scheme, Static U(4)-Spin Symmetry for Light-Quarks and "Exotic" Hadrons
Shin Ishida
Several years ago we have proposed a manifestly covariant -classification scheme of hadrons, which maintains the successful framewo…
Analysis of the generation of photon pairs in periodically poled lithium niobate
Jonas Soderholm, Keiichi Hirano, Shigehiko Mori +2
The process of spontaneous parametric down-conversion (SPDC) in nonlinear crystals makes it fairly easy to generate entangled photon states. It has been known for some time that th…
Quantum anomaly and geometric phase; their basic differences
Kazuo Fujikawa
It is sometimes stated in the literature that the quantum anomaly is regarded as an example of the geometric phase. Though there is some superficial similarity between these two no…
Berry's phases and topological properties in the Born-Oppenheimer approximation
Kazuo Fujikawa
The level crossing problem is neatly formulated by the second quantized formulation, which exhibits a hidden local gauge symmetry. The analysis of geometric phases is reduced to a…
