- Matsubara_frequency abstract "In thermal quantum field theory, the Matsubara frequency summation is the summation over discrete imaginary frequency. It takes the following form,where the frequencies are usually taken from either of the following two sets (with ):first set: , bosonic frequencies,second set: , fermionic frequencies.The summation will converge if g(z=iω) tends to 0 in z→∞ limit in a manner faster than . The summation over bosonic frequencies is denoted as SB (with η=+1), while that over fermionic frequencies is denoted as SF (with η=-1). η is the statistical sign.In addition to thermal quantum field theory, the Matsubara frequency summation method plays also an essential role in the diagrammatic approach to solid-state physics, namely, if one considers the diagrams at finite temperature.Generally speaking, if at T=0 K a certain Feynman diagram is represented by an integral , at finite temperature it is given by the sum .".
