Quantum criticality and non-Fermi liquids: the Wilsonian renormalization group perspective
Mateusz Homenda, Pawel Jakubczyk, Hiroyuki Yamase
We develop a theoretical framework based on the nonperturvative renormalization group (RG) in the one-particle irreducible (Wetterich) formulation to tackle the interplay of couple…
Generalized Hertz action and quantum criticality of two-dimensional Fermi systems
Mateusz Homenda, Paweł Jakubczyk, Hiroyuki Yamase
We reassess the structure of the effective action and quantum critical singularities of two-dimensional Fermi systems characterized by the ordering wavevector . B…
Critical temperature and Ginzburg region near a quantum critical point in two-dimensional metals
J. Bauer, P. Jakubczyk, W. Metzner
We compute the transition temperature and the Ginzburg temperature above near a quantum critical point at the boundary of an ordered phase with a broken dis…
Nematic Quantum Criticality Without Order
Hiroyuki Yamase, Pawel Jakubczyk, Walter Metzner
We consider a two-dimensional interacting Fermi system which displays a nematic phase within mean-field theory. The system is analyzed using a non-perturbative renormalization-grou…
Singular non-ordering susceptibility at a Pomeranchuk instability
Hiroyuki Yamase, Pawel Jakubczyk
We study magnetic susceptibilities of two-dimensional itinerant electron systems exhibiting symmetry-breaking Fermi surface distortions, the so-called d-wave Pomeranchuk instabilit…
Finite temperature crossovers near quantum tricritical points in metals
P. Jakubczyk, J. Bauer, W. Metzner
We present a renormalization group treatment of quantum tricriticality in metals. Applying a set of flow equations derived within the functional renormalization group framework we…
