Ultra-broadband photodetection of Weyl semimetal TaAs up to infrared 10 μm range at room temperature
Shumeng Chi, Zhilin Li, Ying Xie +8
Photodetectors with broadband optical response have promising applications in many advanced optoelectronic and photonic devices. Especially, those with the detection range up to mi…
Symmetrical broken and nonlinear response of Weyl semimetal TaAs influenced by the topological surface states and Weyl nodes
Shumeng Chi, Zhilin Li, Haohai Yu +4
A Weyl semimetal (WSM) features Weyl fermions in its bulk and topological surface states on surfaces, and is novel material hosting Weyl fermions, a kind of fundamental particles.…
The green light generation by self-frequency-doubled Yb:YCOB crystal
Qiannan Fang, Haohai Yu, Huaijin Zhang +1
Taking advantages of the broad emission bands of a Yb3+ doped calcium yttrium oxoborate (Yb:YCOB) crystal cut along the optimized direction out of principle planes with the maximum…
Broadband black phosphorus optical modulator in visible to mid-infrared spectral range
Rui Zhang, Yuxia Zhang, Haohai Yu +5
Black phosphorous (BP), a two-dimensional (2D) material, has a direct bandgap, which fills up the bandgap lacuna left by graphene topological insulators and transition-metal dichal…
Thermally driven continuous-wave and pulsed optical vortex
Yitian Ding, Miaomiao Xu, Yongguang Zhao +4
We demonstrated the continuous-wave (cw) and pulsed optical vortex with topological charges driven by heat generated during the lasing process without introducing the astigmatism e…
Crossover of Magnetoresistance from Fourfold to Twofold Symmetry in SmB6 Single Crystal, a topological Kondo insulator
Zengji Yue, Xiaolin Wang, Duanliang Wang +3
Topological Kondo insulators have been attracting great attention from the condensed-matter physics community due to their fascinating topological and strongly correlated propertie…
Resolving magnetic frustration in a pyrochlore lattice
Jiyang Wang, Yejun Feng, R. Jaramillo +3
CeFe is a geometrically frustrated ferromagnet that lies close to an instability at which a subtle change in the lattice symmetry couples to a transition to antiferromagnetism.…
Order parameter fluctuations at a buried quantum critical point
Yejun Feng, Jiyang Wang, R. Jaramillo +7
Quantum criticality is a central concept in condensed matter physics, but the direct observation of quantum critical fluctuations has remained elusive. Here we present an x-ray dif…
