Euclidean path integral of the scalar Lee-Wick model
Seiji Sakoda, Kohei Suzuki
On the basis of the canonical quantization procedure, in which we need the indefinite metric Hilbert space, we formulate field diagonal representation for the scalar Lee-Wick model…
Path Integrals of the Vector Field --- Covariance of a Path Integral ---
Seiji Sakoda
On the basis of the canonical quantization procedure of a system defined on a cubic lattice, we propose a new method, in which resolutions of unity expressed in terms of eigenvecto…
Path integrals of systems on the half-line
Seiji Sakoda
It is wellknown that the Feynman kernel for the free particle on the half-line can be expressed as a sum over classical paths if we take the contribution from the reflected path in…
Decomposition of the Feynman kernel for a particle in a box
Seiji Sakoda
We study the decomposition of the Feynman kernel for a particle in a box with potential to find that the wellknown phase factor , which is correct for the case of…
Path integrals of a particle in a finite interval and on the half-line
Seiji Sakoda
We make use of point transformations to introduce new canonical variables for systems defined on a finite interval and on the half-line so that new position variables should take a…
On the effective potential of Duru-Kleinert path integrals
Seiji Sakoda
We propose a new method to evaluate the effective potential in the path integral for the fixed-energy amplitude as well as for the pseudotime evolution kernel in the formalism by D…
