Efficient Quasiparticle Determination beyond the Diagonal Approximation via Random Compression
Annabelle Canestraight, Xiaohe Lei, Khaled Ibrahim +1
Calculations of excited states in Green's function formalism often invoke the diagonal approximation, in which the quasiparticle states are taken from a mean-field calculation. Her…

On the unimportance of memory for the time non-local components of the Kadanoff-Baym equations
Cian C. Reeves, Yuanran Zhu, Chao Yang +1
The generalized Kadanoff-Baym ansatz (GKBA) is an approximation to the Kadanoff-Baym equations (KBE), that neglects certain memory effects that contribute to the Green's function a…
