Direct Observation of Coherent Longitudinal and Shear Acoustic Phonons in TaAs Using Ultrafast X-ray Diffraction
Min-Cheol Lee, N. Sirica, S. W. Teitelbaum +18
Using femtosecond time-resolved X-ray diffraction, we investigated optically excited coherent acoustic phonons in the Weyl semimetal TaAs. The low symmetry of the (112) surface pro…
Giant Grüneisen parameter in a strain-tuned superconducting quantum paraelectric: A consequence of the vanishing ferroelectric phonon energy
Jacob Franklin, Bochao Xu, Donovan Davino +3
Superconductivity and ferroelectricity are typically incompatible because the former needs free carriers, but the latter is usually suppressed by free carriers, unless their concen…
Optical observation of spin-density-wave fluctuations in Ba122 iron-based superconductors
B. Xu, Y. M. Dai, H. Xiao +8
In iron-based superconductors, a spin-density-wave (SDW) magnetic order is suppressed with doping and unconventional superconductivity appears in close proximity to the SDW instabi…
Spin-flop transition and magnetic phase diagram in CaCoAs revealed by torque measurements
W. Zhang, K. Nadeem, H. Xiao +4
The magnetic properties of CaCoAs single crystal was systematically studied by using dc magnetization and magnetic torque measurements. A paramagnetic to antiferromagne…
Statistical study of conductance properties in one-dimensional quantum wires focussing on the 0.7 anomaly
L. W. Smith, H. Al-Taie, F. Sfigakis +9
The properties of conductance in one-dimensional (1D) quantum wires are statistically investigated using an array of 256 lithographically-identical split gates, fabricated on a GaA…
A low-temperature device architecture for the statistical study of electrical characteristics of 256 quantum devices
H. Al-Taie, L. W. Smith, B. Xu +7
Research in the field of low-temperature electronics is limited by the small number of electrical contacts available on cryogenic set ups. This not only restricts the number of dev…
Electron-phonon coupling in the superconducting single crystal RbFeSe
B. Xu, Y. M. Dai, J. Han +6
The optical properties of the superconducting single crystal RbFeSe with 31 K have been measured over a wide frequency range in the plane…
Hidden -Linear Scattering Rate in BaKFeAs Revealed by Optical Spectroscopy
Y. M. Dai, B. Xu, B. Shen +5
The optical properties of BaKFeAs have been determined in the normal state for a number of temperatures over a wide frequency range. Two Drude terms, re…
Cryogenic on-chip multiplexer for the study of quantum transport in 256 split-gate devices
H. Al-Taie, L. W. Smith, B. Xu +7
We present a multiplexing scheme for the measurement of large numbers of mesoscopic devices in cryogenic systems. The multiplexer is used to contact an array of 256 split gates on…
Filamentary superconductivity across the phase diagram of Ba(Fe,Co)As
H. Xiao, T. Hu, S. K. He +10
We show magnetotransport results on Ba(FeCo)As () single crystals. We identify the low temperature resistance step at 23 K in the parent c…
Pseudogap in underdoped BaKFeAs as seen via optical conductivity
Y. M. Dai, B. Xu, B. Shen +4
We report the observation of a pseudogap in the \emph{ab}-plane optical conductivity of underdoped BaKFeAs ( and 0.12) single crystals. Both samp…
Doping evolution of the optical scattering rate and effective mass of Bi(2)Sr(2-x)La(x)CuO(6)
Y. M. Dai, B. Xu, P. Cheng +4
We determined the optical conductivity of Bi(2)Sr(2-x)La(x)CuO(6) at dopings covering the phase diagram from the underdoped to the overdoped regimes. The frequency dependent scatte…
