Symmetry-projected variational calculations with the numerical suite TAURUS I. Variation after particle-number projection

Benjamin Bally, Adrián Sánchez-Fernández, Tomás R. Rodríguez

We present the numerical code TAURUS_vap that solves the variation after particle-number projection equations for symmetry-unrestricted real Bogoliubov quasiparticle states represe…
