On the Magic Matrix by Makhlin and the B-C-H Formula in SO(4)
Kazuyuki Fujii, Tatsuo Suzuki
A closed expression to the Baker-Campbell-Hausdorff (B-C-H) formula in SO(4) is given by making use of the magic matrix by Makhlin. As far as we know this is the {\bf first nontriv…
How To Treat An N-Level System : A Proposal
Kazuyuki Fujii
In this paper we propose a Hamiltonian of the n-level system by making use of generalized Pauli matrices.
Introduction to Coherent States and Quantum Information Theory
Kazuyuki Fujii
The purpose of this paper is to introduce several basic theorems of coherent states and generalized coherent states based on Lie algebras su(2) and su(1,1), and to give some applic…
Coherent states, Path integral, and Semiclassical approximation
K. Funahashi, T. Kashiwa, S. Sakoda +1
Using the generalized coherent states we argue that the path integral formulae for and (in the discrete series) are WKB exact,if the starting point is expressed a…
