Nambu-Covariant Many-Body Theory II: Self-Consistent Approximations
M. Drissi, A. Rios, C. Barbieri
The theory of Self-Consistent Green's Function (SCGF) is reformulated in an explicit Nambu-covariant fashion for applications to many-body systems at non-zero temperature in symmet…

Nambu-Covariant Many-Body Theory I: Perturbative Approximations
M. Drissi, A. Rios, C. Barbieri
Symmetry-breaking considerations play an important role in allowing reliable and accurate predictions of complex systems in quantum many-body simulations. The general theory of per…
