Charge-density wave transition in magnetic topological semimetal EuAl
R. Yang, C. C. Le, P. Zhu +5
The interplay among topology, charge-density wave (CDW), and magnetism can give rise to a plethora of exotic quantum phenomena. Recently, a group of magnetic topological semimetals…
Temperature-driven Topological Phase Transition and Intermediate Dirac Semimetal Phase in ZrTe
B. Xu, L. X. Zhao, P. Marsik +6
We present an infrared spectroscopy study of ZrTe, which confirms a recent theoretical proposal that this material exhibits a temperature-driven topological quantum phase trans…
Optical study of Dirac fermions and related phonon anomalies in antiferromagnetic compound CaFeAsF
B. Xu, H. Xiao, B. Gao +8
We performed optical studies on CaFeAsF single crystals, a parent compound of the 1111-type iron-based superconductors that undergoes a structural phase transition from tetragonal…
Precision Measurement of the Proton Flux in Primary Cosmic Rays from 1 GV to 1.8 TV with the Alpha Magnetic Spectrometer on the International Space Station
Cristina Consolandi
A precision measurement of the proton flux in primary cosmic rays with rigidity from 1 GV to 1.8 TV is presented based on 300 million events. The results show that the proton flux…
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…
