Note on the Time Dependent Variational Approach with Quasi-Spin Squeezed State for Pairing Model
Y. Tsue, H. Akaike
Abstract
A simple many-fermion system in which there exists N identical fermions in a single spherical orbit with pairing interaction is treated by means of the time-dependent variational approach with a quasi-spin squeezed state with the aim of going beyond the time-dependent Hartree-Fock or Bogoliubov theory. It is shown that the ground state energy is reproduced well analytically in this approach.
