Quantum fluctuations approach to the nonequilibrium $GW$ approximation

Condensed Matter Physics, 2022, vol. 25, No. 2, 23401 The quantum dynamics of fermionic or bosonic many-body systems following external excitation can be successfully studied using two-time nonequilibrium Green's functions (NEGF) or single-time reduced density matrix methods. Approximations are...
