Momentum expansions in finite-density perturbative calculations
Mika Nurmela, Juuso Österman
Complex-valued Feynman integrals in the imaginary time formalism and zero-temperature limit suffer from particular types of infrared divergences that can not be regulated by integr…

Augmenting the residue theorem with boundary terms in finite-density calculations
Tyler Gorda, Juuso Österman, Saga Säppi
At zero temperature and finite chemical potential, -dimensional loop integrals with complex-valued integrands in the imaginary-time formalism yield results dependent on the inte…
