BCS-BEC Crossover of Triplet Exciton Condensation in Bilayer Systems
Hidemaro Suwa, Shang-Shun Zhang, Cristian D. Batista
We study the BCS-BEC crossover phenomenon of triplet exciton condensation using a half-filled bilayer Hubbard model. We calculate the dynamical spin structure factor and the excito…
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…
Odd frequency pairing in a quantum critical metal
Yi-Ming Wu, Shang-Shun Zhang, Artem Abanov +1
We analyze a possibility for odd-frequency pairing near a quantum critical point(QCP) in a metal. We consider a model with dynamical pairing interaction (the…
Evidence of Two-Spinon Bound States in the Magnetic Spectrum of BaCoSbO
E. A. Ghioldi, Shang-Shun Zhang, Yoshitomo Kamiya +3
Recent inelastic neutron scattering (INS) experiments of the triangular antiferromagnet BaCoSbO revealed strong deviations from semiclassical theories. We demonstrate t…
