singlet.m

Returns a two-spin singlet state.

Syntax

    rho=singlet(spin_system,spin_a,spin_b)

Parameters

  spin_a  - the number of the first spin in the 
            singlet state

  spin_b  - the number of the second spin in the 
            singlet state

Outputs

  rho     - a density matrix (Hilbert space) or
            a state vector (Liouville space)
