Dear Editors, Tungsten ditelluride (WTe2) is a layered transition-metal dichalcogenide (TMD). The tungsten layers are clipped by adjacent chalcogenide layers. The sandwich structure stacks along the c-axis with Va...

Performances of superconducting nanowire single-photon detectors(SNSPDs) based on low TCmaterials strongly depend on the operating temperatures. We have fabricated infrared-sensitive niobium SNSPDs based on doped niob...

We demonstrate the effect of different coupling strengths between a microscopic two-level system(TLS)and a microwave field on the dynamics of a qubit—TLS system when the bipartite system is subject to resonant microw...

We measured the infrared reflectivity of BaFe1.904Ni0.096As2 single crystal from room temperature down to 20 K. Two Drude terms and a Lorentz term well describe the real part of the optical conductivity σ1 (ω). We...
