Field-theoretic functional renormalization group formalism for non-Fermi liquids and its application to the antiferromagnetic quantum critical metal in two dimensions
Francisco Borges, Anton Borissov, Ashutosh Singh +2
To capture the universal low-energy physics of metals within effective field theories, one has to generalize the usual notion of scale invariance and renormalizable field theory du…
Noncommutativity between the low-energy limit and integer dimension limits in the -expansion: a case study of the antiferromagnetic quantum critical metal
Andres Schlief, Peter Lunts, Sung-Sik Lee
We study the field theory for the SU() symmetric antiferromagnetic quantum critical metal with a one-dimensional Fermi surface embedded in general space dimensions between two…
Emergence of a control parameter for the antiferromagnetic quantum critical metal
Peter Lunts, Andres Schlief, Sung-Sik Lee
We study the antiferromagnetic quantum critical metal in space dimensions by extending the earlier one-loop analysis [Sur and Lee, Phys. Rev. B 91, 125136 (2015)] to higher-l…
Exact critical exponents for the antiferromagnetic quantum critical metal in two dimensions
Andres Schlief, Peter Lunts, Sung-Sik Lee
Unconventional metallic states which do not support well defined single-particle excitations can arise near quantum phase transitions as strong quantum fluctuations of incipient or…
