Q-boson coherent states and para-Grassmann variables for multi-particle states
Romina A. Ramirez, Gerardo L. Rossini, Daniel C. Cabra +1
We describe coherent states and associated generalized Grassmann variables for a system of independent -boson modes. A resolution of unity in terms of generalized Berezin in…
