Abstract:
A new functional representation for the Hubbard model is obtained.
It uses a construction of “generalized coherent states with
respect to the supergroup”. A way is proposed for constructing
the generators of superalgebras that can be realized in problems
requiring allowance to be made for strong Coulomb interaction. The
physical meaning of the amplitude of the supercoordinate as the
mass of the particles in the fermion sector is discussed.
