Universal dynamics of a pair condensate
Qing Huang, Hao Zhang, Yiqing Hao +10
Pair condensates appear in multiple branches of physics, always introducing exotic phenomena. The pair condensate in quantum magnetism is the spin nematic, whose static (quadrupola…
Electronic Raman scattering of antiferromagnetic excitonic insulators
Hidemaro Suwa, Shang-Shun Zhang, Cristian D. Batista
The excitonic insulator, a quantum mechanical state arising from exciton condensation, was proposed theoretically many years ago but has yet to be experimentally confirmed. The dis…
Tetrahedral triple-Q magnetic ordering and large spontaneous Hall conductivity in the metallic triangular antiferromagnet Co1/3TaS2
Pyeongjae Park, Woonghee Cho, Chaebin Kim +14
The triangular lattice antiferromagnet (TLAF) has been the standard paradigm of frustrated magnetism for several decades. The most common magnetic ordering in insulating TLAFs is t…
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…
Free energy and specific heat near a quantum critical point of a metal
Shang-Shun Zhang, Erez Berg, Andrey V. Chubukov
We analyze free energy and specific heat for fermions interacting with gapless bosons at a quantum-critical point (QCP) in a metal. We use the Luttinger-Ward-Eliashberg formula for…
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…
