Algebraic relations between Dyson and Liouvillian self-energy field approaches

Mostrar todas las versiones(2)

Through the superoperator algebraic formalism it is shown that Liouvillian self-energies derived from the equations of motion hierarchy for two-time propagators in stationary states of time independent Hamiltonians of N-particle systems are closely related to those obtained from the solution of the...
