Analytic continuation of multipoint correlation functions
Anxiang Ge, Johannes Halbinger, Seung-Sup B. Lee +2
Conceptually, the Matsubara formalism (MF), using imaginary frequencies, and the Keldysh formalism (KF), formulated in real frequencies, give equivalent results for systems in ther…
Emergent Properties of the Periodic Anderson Model: a High-Resolution, Real-Frequency Study of Heavy-Fermion Quantum Criticality
Andreas Gleis, Seung-Sup B. Lee, Gabriel Kotliar +1
We study paramagnetic quantum criticality in the periodic Anderson model (PAM) using cellular dynamical mean-field theory, with the numerical renormalization group (NRG) as an impu…
Symmetric improved estimators for multipoint vertex functions
Jae-Mo Lihm, Johannes Halbinger, Jeongmin Shim +3
Multipoint vertex functions, and the four-point vertex in particular, are crucial ingredients in many-body theory. Recent years have seen significant algorithmic progress toward nu…
