convolution_density_matrix() [4/4]

template<typename T , class GG >

void cntr::convolution_density_matrix	(	int	tstp,
		cdmatrix &	rho,
		GG &	A,
		GG &	B,
		T	beta,
		T	h,
		int	SolveOrder
	)

Returns the result of the contour convolution for a density matrix

Purpose

Calls convolution routines to compute contour convolution \(\rho=-i (A*B)^<\). The objects A and B are of the class type 'GG'. Works for a scalar and square matrices.

Parameters

tstp	[int] given time-step
rho	[std::complex] Matrix to which the result of the convolution is given
A	[GG] contour Green's function
B	[GG] contour Green's function
beta	inversed temperature
h	time interval
SolveOrder	[int] integrator ordder
