Evaluate a bubble diagram ( \(C\)) from two-time contour functions \(A,B\) at the time step; \( C_{c_1,c_2}(t_1,t_2) = i A_{a_1,a_2}(t_t,t_2) * B_{b_2,b_1}(t_2,t_1) \).

Purpose

Evaluate the two-time contour function \(C\) represented as a bubble diagram with two-time functions \(A,B\); \( C_{c_1,c_2}(t_1,t_2) = i A_{a_1,a_2}(t_t,t_2) * B_{b_2,b_1}(t_2,t_1) \). 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 \( i A_{a_1,a_2}(t_t,t_2) * B_{b_2,b_1}(t_2,t_1)\) is stored at \( C_{c_1,c_2}(t_1,t_2)\). Here \(A\) and \(B\) are assumed to have the hermitian symmetry.

Parameters

tstp	Time step.
C	Two-time contour object in the Matrix form defined as \( C_{c_1,c_2}(t_1,t_2) = i A_{a_1,a_2}(t_t,t_2) * B_{b_2,b_1}(t_2,t_1) \).
c1	First index of the matrix \(C\).
c2	Second index of the matrix \(C\).
A	Two-time contour object in the Matrix form with the hermitian symmetry.
a1	First index of the matrix \(A\).
a2	Second index of the matrix \(A\).
B	Two-time contour object in the Matrix form with the hermitian symmetry.
b1	'Second' index of the matrix \(B\).
b2	'First' index of the matrix \(B\).
