void cntr::Bubble2	(	int	tstp,
		GGC &	C,
		GGA &	A,
		GGB &	B
	)

Evaluate a bubble diagram ( \(C\)) from two-time contour functions \(A,B\) at the time step; \( C_{0,0}(t_1,t_2) = i A_{0,0}(t_1,t_2) * B_{0,0}(t_1,t_2) \).

Purpose

Evaluate the two-time contour function \(C\) represented as a bubble diagram with two-time functions \(A,B\); \( C_{0,0}(t_1,t_2) = i A_{0,0}(t_1,t_2) * B_{0,0}(t_1,t_2) \). Here it is assmued that \(A\), \(B\) and \(C\) are \(1\times 1\) matrices. This evaluation is done at the time step (i.e. \( t_1 \) or \( t_2 \) is the time step) for all components (retarded, lesser, left-mixing and Matsubara). The evaluated value of \( i A_{0,0}(t_1,t_2) * B_{0,0}(t_1,t_2)\) is stored at \( C_{0,0}(t_1,t_2)\). Here \(A\) and \(B\) are assumed to have the hermitian symmetry.

Parameters

tstp	Time step.
C	Two-time contour object in the \(1\times 1\)-Matrix form defined as \( C_{0,0}(t_1,t_2) = i A_{0,0}(t_1,t_2) * B_{0,0}(t_1,t_2) \).
A	Two-time contour object in the \(1\times 1\)-Matrix form with the hermitian symmetry.
B	Two-time contour object in the \(1\times 1\)-Matrix form with the hermitian symmetry.
