Transient Higgs oscillations and high-order nonlinear light-Higgs coupling in terahertz-wave drivenNbN superconductor
Z. X. Wang, J. R. Xue, H. K. Shi +6
We study the nonlinear optical response in a superconducting NbN thin film with strong terahertz (THz)wave. Besides the expected third harmonic generation, we observe a new transie…
Prominent role of spin-orbit coupling in FeSe
Mingwei Ma, Philippe Bourges, Yvan Sidis +6
In most existing theories for iron-based superconductors, spin-orbit coupling (SOC) has been assumed insignificant. Even though recent experiments have revealed an influence of SOC…
The nature of effective interaction in cuprate superconductors: a sign-problem-free quantum Monte-Carlo study
Zi-Xiang Li, Fa Wang, Hong Yao +1
Superconductivity is an emergent phenomena in the sense that the energy scale associated with Cooper pairing is generically much lower than the typical kinetic energy of electrons.…
What makes the Tc of monolayer FeSe on SrTiO3 so high: a sign-problem-free quantum Monte Carlo study
Zi-Xiang Li, Fa Wang, Hong Yao +1
Monolayer FeSe films grown on SrTiO3 (STO) substrate show superconducting gap-opening temperatures (Tc) which are almost an order of magnitude higher than those of the bulk FeSe an…
Magnetic interactions in FeSe studied by first principle calculations
Shuai Wang, Fa Wang
Based on first principle calculations we have investigated the evolution of magnetism in free-standing monolayer FeSe with respect to lattice constant and magnetism in bulk FeSe. T…
Longitudinal spin excitations and magnetic anisotropy in antiferromagnetically ordered BaFe2As2
Chong Wang, Rui Zhang, Fa Wang +4
We report on a spin-polarized inelastic neutron scattering study of spin waves in the antiferromagnetically ordered state of BaFe2As2. Three distinct excitation components are iden…
