Type-Bound Procedures
procedure, public :: diffusion_current => spinactive_diffusion_current
-
private pure function spinactive_diffusion_current(this, G0, G1) result(I)
Calculate the matrix current at an interface with spin-active properties. The equations implemented here should be valid for an arbitrary interface polarization, and up to 2nd order in the transmission probabilities and spin-mixing angles of the interface.
Arguments
Type Intent Optional Attributes Name class(spinactive), intent(in) :: this type(nambu), intent(in) :: G0 Propagator matrices
type(nambu), intent(in) :: G1 Propagator matrices
Return Value type(nambu)
Matrix current
procedure, public :: kinetic_current => spinactive_kinetic_current
-
private pure subroutine spinactive_kinetic_current(this, G0, G1, C0, C1)
Calculate the kinetic boundary coefficients at an interface with spin-active properties. These can be used to calculate the generalized current according to J = C₀H₀ - C₁H₁.
Arguments
Type Intent Optional Attributes Name class(spinactive), intent(in) :: this type(propagator), intent(in) :: G0 Propagator (this side)
type(propagator), intent(in) :: G1 Propagator (other side)
complex(kind=wp), intent(out), dimension(0:7,0:7) :: C0 Boundary coefficient (this side)
complex(kind=wp), intent(out), dimension(0:7,0:7) :: C1 Boundary coefficient (other side)
procedure, public :: update_prehook => spinactive_update_prehook
-
private subroutine spinactive_update_prehook(this)
Updates the internal variables associated with spin-active interfaces.
Arguments
Type Intent Optional Attributes Name class(spinactive), intent(inout) :: this
