public interface propagator
Module Procedures
private pure function propagator_construct_vacuum() result(this)
Construct a vacuum propagator, i.e. a propagator which satisfies G=0.
Arguments
NoneReturn Value type(propagator)
Constructed object
private pure function propagator_construct_riccati(g, gt, dg, dgt) result(this)
Construct an arbitrary state by explicitly providing Riccati parameters. Unspecified Riccati parameters default to zero due to spin constructors. The distribution function defaults to equilibrium at zero temperature.
Arguments
| Type | Intent | Optional | Attributes | Name | ||
|---|---|---|---|---|---|---|
| type(spin), | intent(in) | :: | g |
Riccati parameter γ |
||
| type(spin), | intent(in) | :: | gt |
Riccati parameter γ~ |
||
| type(spin), | intent(in), | optional | :: | dg |
Riccati parameter ∇γ |
|
| type(spin), | intent(in), | optional | :: | dgt |
Riccati parameter ∇γ~ |
Return Value type(propagator)
Constructed object
private pure function propagator_construct_bcs(energy, gap) result(this)
Constructs the state of a a BCS superconductor at a given energy, which may have an imaginary term representing inelastic scattering. The second argument 'gap' is used to provide the superconducting order parameter Δ. The distribution function defaults to equilibrium at zero temperature.
Arguments
| Type | Intent | Optional | Attributes | Name | ||
|---|---|---|---|---|---|---|
| complex(kind=wp), | intent(in) | :: | energy |
Quasiparticle energy |
||
| complex(kind=wp), | intent(in) | :: | gap |
Order parameter |
Return Value type(propagator)
