Geometric Phase and Chiral Anomaly in Path Integral Formulation
Kazuo Fujikawa
All the geometric phases, adiabatic and non-adiabatic, are formulated in a unified manner in the second quantized path integral formulation. The exact hidden local symmetry inheren…

Adiabatic approximation in the second quantized formulation
Kazuo Fujikawa
Recently there have been some controversies about the criterion of the adiabatic approximation. It is shown that an approximate diagonalization of the effective Hamiltonian in the…

On the separability criterion for continuous variable systems
Kazuo Fujikawa
We present an elementary and explicit proof of the separability criterion for continuous variable two-party Gaussian systems. Our proof is based on an elementary formulation of unc…
