Inhomogeneous transformations in a gauged twistor formulation of a massive particle
Shinichi Deguchi, Satoshi Okano
In this paper, we show that the mass-shell constraints in the gauged twistor formulation of a massive particle given in [Deguchi and Okano, Phys. Rev. D 93, 045016 (2016) [Erratum…
Quantization of the damped harmonic oscillator based on a modified Bateman Lagrangian
Shinichi Deguchi, Yuki Fujiwara
An approach to quantization of the damped harmonic oscillator (DHO) is developed on the basis of a modified Bateman Lagrangian (MBL); thereby some quantum mechanical aspects of the…
Square-integrable eigenfunctions in quantizing the Bateman oscillator model
Shinichi Deguchi, Yuki Fujiwara
In a recent paper [Phys. Lett. A 383 (2019) 2836; arXiv:1906.05121 [quant-ph]], Bagarello, Gargano, and Roccati have claimed that no square-integrable vacuum exists in quantizing t…
A new magnetic monopole inspired by Berry's phase
Shinichi Deguchi, Kazuo Fujikawa
A new static and azimuthally symmetric magnetic monopolelike object, which looks like a Dirac monopole when seen from far away but smoothly changes to a dipole near the monopole po…
Topology change from a monopole to a dipole in Berry's phase
Shinichi Deguchi, Kazuo Fujikawa
The smooth topology change of Berry's phase from a Dirac monopole-like configuration to a dipole configuration, when one approaches the monopole position in the parameter space, is…
No anomalous canonical commutators induced by Berry's phase
Shinichi Deguchi, Kazuo Fujikawa
The monopole-like singularity of Berry's adiabatic phase in momentum space and associated anomalous Poisson brackets have been recently discussed in various fields. With the help o…
