Fermi surface truncation from thermal nematic fluctuations
Hiroyuki Yamase, Walter Metzner
We analyze how thermal fluctuations near a finite temperature nematic phase transition affect the spectral function for single-electron excitations in a two-dimensio…
Singular order parameter interaction at nematic quantum critical point in two dimensional electron systems
Stephan Thier, Walter Metzner
We analyze the infrared behavior of effective N-point interactions between order parameter fluctuations for nematic and other quantum critical electron systems with a scalar order…
Functional renormalization group approach to correlated fermion systems
Walter Metzner, Manfred Salmhofer, Carsten Honerkamp +2
Numerous correlated electron systems exhibit a strongly scale-dependent behavior. Upon lowering the energy scale, collective phenomena, bound states, and new effective degrees of f…
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…
