Chiral boson on a circle revisited
It is a well known result that the scalar field spectrum is composed of two
chiral particles (Floreanini-Jackiw particles) of opposite chiralities. Also,
that a Siegel particle spectrum is formed by a nonmover field (a Hull's noton)
and a FJ particle. We show here that, in fact, the spectrum of the chiral boson
on a circle has a particle not present in its currently well known spectrum.Comment: 11 pages, Latex. Final version to appear in Braz. J. Phy
Dual projection in a two-dimensional curved expanding universe
It is a well known result that the scalar field is composed of two chiral
particles (Floreanini-Jackiw particles) of opposite chiralities. Also, that a
Siegel particle spectrum is formed by a nonmover field (a Hull's noton) and a
FJ particle. In this work we show that in a scalar field spectrum, in a curved
expanding universe scenario, we can find two dynamical chiral fields.Comment: 6 pages, Revtex. Final version to appear in Int. J. Mod. Phys.
