We are exploiting the results of the exact solution for the ground state of the one-dimensional spinless quantum gas of Fermions with =x 2 ij particle-particle interaction, and analyze particle-number uctuations for = -1 4 ; 0; and 2. These are suppressed by repulsive interaction ( ¿ 0), enhanced by
We use the collective field theory known for the Calogero Sutherland model to study a variety of low-energy properties. These include the ground state energy in a confining potential up to the two leading orders in the particle number, the dispersion relation of sound modes with a comparison to the
