Berry's phase and chiral anomalies
Kazuo Fujikawa, Koichiro Umetsu
The basic materials of Berry's phase and chiral anomalies are presented to appreciate the phenomena related to those notions. As for Berry's phase, a general survey of the subject…
A path integral derivation of the equations of anomalous Hall effect
Kazuo Fujikawa, Koichiro Umetsu
A path integral (Lagrangian formalism) is used to derive the effective equations of motion of the anomalous Hall effect with Berry's phase on the basis of the adiabatic condition $…
Lensing of Dirac monopole in Berry's phase
Kazuo Fujikawa, Koichiro Umetsu
Berry's phase, which is associated with the slow cyclic motion with a finite period, looks like a Dirac monopole when seen from far away but smoothly changes to a dipole near the l…
Parity and CP operations for Majorana neutrinos
Kazuo Fujikawa
The parity transformation law of the fermion field is usually defined by the "-parity" with eigenvalues , while the "$…
Path integral of neutrino oscillations
Kazuo Fujikawa
We propose an idea of the constrained Feynman amplitude for the scattering of the charged lepton and the virtual W-boson, , from which the conventi…
Parity of the neutron consistent with neutron-antineutron oscillations
Kazuo Fujikawa, Anca Tureanu
In the analysis of neutron-antineutron oscillations, it has been recently argued in the literature that the use of the parity which…
