Density of states and spectral function of a superconductor out of a quantum-critical metal
Shang-Shun Zhang, Andrey V. Chubukov
We analyze the validity of a quasiparticle description of a superconducting state at a metallic quantum-critical point (QCP). A normal state at a QCP is a non-Fermi liquid with no…
Superconductivity out of a non-Fermi liquid. Free energy analysis
Shang-Shun Zhang, Yi-Ming Wu, Artem Abanov +1
In this paper, we present in-depth analysis of the condensation energy for a superconductor in a situation when superconductivity emerges out of a non-Fermi liquid due to pai…
Interplay between superconductivity and non-Fermi liquid at a quantum-critical point in a metal. VI. The model and its phase diagram at
Shang-Shun Zhang, Yi-Ming Wu, Artem Abanov +1
In this paper, the sixth in series, we continue our analysis of the interplay between non-Fermi liquid and pairing in the effective low-energy model of fermions with singular dynam…
Interplay between superconductivity and non-Fermi liquid at a quantum-critical point in a metal: V. The model and its phase diagram. The case
Yi-Ming Wu, Shang-Shun Zhang, Artem Abanov +1
This paper is a continuation and a partial summary of our analysis of the pairing at a quantum-critical point (QCP) in a metal for a set of quantum-critical systems, whose low-ener…
Interplay between superconductivity and non-Fermi liquid at a quantum-critical point in a metal. IV: The model and its phase diagram at
Yi-Ming Wu, Shang-Shun Zhang, Artem Abanov +1
In this paper we continue our analysis of the interplay between the pairing and the non-Fermi liquid behavior in a metal for a set of quantum-critical (QC) systems with an effectiv…
Pairing from strong repulsion in triangular lattice Hubbard model
Shang-Shun Zhang, Wei Zhu, Cristian D. Batista
We propose a paring mechanism between holes in the dilute limit of doped frustrated Mott insulators. Hole pairing arises from a hole-hole-magnon three-body bound state. This pairin…
