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…

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 $V (Ω_{n}) \sim 1/∣ Ω_{n} ∣^{γ}$ (the…

Evidence of Two-Spinon Bound States in the Magnetic Spectrum of Ba $_{3}$ CoSb $_{2}$ O $_{9}$

E. A. Ghioldi, Shang-Shun Zhang, Yoshitomo Kamiya +3

Recent inelastic neutron scattering (INS) experiments of the triangular antiferromagnet Ba $_{3}$ CoSb $_{2}$ O $_{9}$ revealed strong deviations from semiclassical theories. We demonstrate t…
