Direct characterization of photo-induced lattice dynamics in BaFe2As2
S. Gerber, K. W. Kim, Y. Zhang +21
Ultrafast light pulses can modify the electronic properties of quantum materials by perturbing the underlying, intertwined degrees of freedom. In particular, iron-based superconduc…
A Random Access Reconfigurable Metamaterial and a Tunable Flat Lens
W. M. Zhu, Q. H. Song, A. Q. Liu +9
The ability to control resonant properties of individual metamolecule in a metamaterial structure will offer an ultimate freedom for dynamically shaping wavefronts of electromagnet…
Ubiquitous antinodal quasiparticles and deviation from simple d-wave form in underdoped Bi-2212
I. M. Vishik, M. Hashimoto, W. -S. Lee +2
The momentum dependence of the superconducting gap in the cuprates has been debated, with most experiments reporting a deviation from a simple form in the underdoped…
Dynamic competition between spin density wave order and superconductivity in underdoped
M. Yi, Y. Zhang, Z. -K. Liu +13
An intriguing aspect of unconventional superconductivity is that it always appears in the vicinity of other competing phases, whose suppression brings the full emergence of superco…
Angle-resolved photoemission spectroscopy study of HgBaCuO
I. M. Vishik, N. Barišić, M. K. Chan +9
HgBaCuO (Hg1201) has been shown to be a model cuprate for scattering, optical, and transport experiments, but angle-resolved photoemission spectroscopy (ARPES) data a…
Electronic structure of BaNiP observed by angle-resolved photoemission spectroscopy
S. Ideta, T. Yoshida, M. Nakajima +16
We have performed an angle-resolved photoemission spectroscopy (ARPES) study of BaNiP which shows a superconducting transition at 2.5 K. We observed hole and e…
