On the Chern-Simons Gauge Theory of Anyons in the Fractional Quantum Hall Effect
Hitoshi Ito
This short note was born out of discussions on anyons in the FQHE at the YITP workshop "Fundamental problems of quantum field theories" (December 19-21, 2001, YITP, Kyoto). At that…

Statistics of the Composite Systems
Hitoshi Ito
The commutation relations of the composite fields are studied in the 3, 2 and 1 space dimensions. It is shown that the field of an atom consisting of a nucleus and an electron fiel…

Two-Body Dirac Equation and Its Wave Function at the Origin
Hitoshi Ito
A relativistic equation is deduced for the bound state of two particles, by assuming a proper boundary condition for the propagation of the negative-energy states. It reduces to th…
