Symmetry breaking and ascending in the magnetic kagome metal FeGe
Shangfei Wu, Mason Klemm, Jay Shah +12
Spontaneous symmetry breaking-the phenomenon where an infinitesimal perturbation can cause the system to break the underlying symmetry-is a cornerstone concept in the understanding…
Charge density wave order in kagome metal AVSb (A= Cs, Rb, K)
Shangfei Wu, Brenden R. Ortiz, Hengxin Tan +4
We employ polarization-resolved electronic Raman spectroscopy and density functional theory to study the primary and secondary order parameters, as well as their interplay, in the…
High magnetic field ultrasound study of spin freezing in LaSrCuO
M. Frachet, S. Benhabib, I. Vinograd +11
High- cuprate superconductors host spin, charge and lattice instabilities. In particular, in the antiferromagnetic glass phase, over a large doping range, lanthanum bas…
Fermion-boson many-body interplay in a frustrated kagome paramagnet
J. -X. Yin, Nana Shumiya, Sougata Mardanya +22
Kagome-net, appearing in areas of fundamental physics, materials, photonic and cold-atom systems, hosts frustrated fermionic and bosonic excitations. However, it is extremely rare…
Hidden magnetism at the pseudogap critical point of a high temperature superconductor
Mehdi Frachet, Igor Vinograd, Rui Zhou +17
The mysterious pseudogap phase of cuprate superconductors ends at a critical hole doping level p* but the nature of the ground state below p* is still debated. Here, we show that t…
Quadrupolar charge dynamics in the nonmagnetic FeSeS superconductors
W. -L. Zhang, S. -F. Wu, S. Kasahara +3
We use polarization-resolved electronic Raman spectroscopy to study charge dynamics in non-magnetic FeSeS superconductor. We observe two features of the quadrupole…
Collective excitations of dynamic Fermi surface deformations in BaFe(AsP)
S. -F. Wu, W. -L. Zhang, D. Hu +7
We use electronic Raman scattering to study the low-energy excitations in BaFe(AsP) ( K) samples. In addition to a superconducting pair brea…
Tetragonal and collapsed-tetragonal phases of CaFe2As2 -- a view from angle-resolved photoemission and dynamical mean field theory
Ambroise van Roekeghem, Pierre Richard, Xun Shi +8
We present a study of the tetragonal to collapsed-tetragonal transition of CaFe2As2 using angle-resolved photoemission experiments and dynamical mean field theory-based electronic…
Raman scattering investigation of large positive magnetoresistance material WTe
W. -D. Kong, S. -F. Wu, P. Richard +5
We have performed polarized Raman scattering measurements on WTe, for which an extremely large positive magnetoresistance has been reported recently. We observe 5 A phonon…
Unconventional Magnetization of Fe3O4 Thin Film Grown on Amorphous SiO2 Substrate
Zhi-Guo Liu, Shang-Fei Wu, Jia-Xin Yin +6
High quality single crystal Fe3O4 thin films with (111) orientation had been prepared on amorphous SiO2 substrate by pulsed laser deposition. The magnetization properties of the fi…
Three-Dimensional Nanoporous Graphene Substrate for Surface-Enhanced Raman Scattering
Zhiqiang Tu, Shangfei Wu, Fan Yang +5
We synthesized three-dimensional nanoporous graphene films by a chemical vapor deposition method with nanoporous copper as a catalytic substrate. The resulting nanoporous graphene…
Controllable growth of 1-7 layers of graphene by chemical vapour deposition
Zhiqiang Tu, Zhuchen Liu, Yongfeng Li +8
We report that graphene films with thickness ranging from 1 to 7 layers can be controllably synthesized on the surface of polycrystalline copper by a chemical vapour deposition met…
Coexistence of orbital degeneracy lifting and superconductivity in iron-based superconductors
H. Miao, L. -M. Wang, P. Richard +10
In contrast to conventional superconducting (SC) materials, superconductivity in high-temperature superconductors (HTCs) usually emerges in the presence of other fluctuating orders…
