The evolution of electron correlation and charge density wave (CDW) in 1T-TaS2 single crystal has been investigated by temperature-dependent Raman scattering, which undergoes two obvious peaks of A1g modes about 70.8 cm-1 and 78.7 cm-1 at 80 K, respectively. The former peak at 70.8 cm-1 is accordant...

Dirac semimetals are materials in which the conduction and the valence bands have robust crossing points protected by topology or symmetry. Recently, a new type of Dirac semimetals, so called the Dirac line-node semimetals (DLNSs), have attracted a lot of attention, as they host robust Dirac points ...

We report an optical spectroscopy study on intermediate valence system Yb1-xLuxAl3 with x=0, 0.25, 0.5, 0.75, and 1. The Kondo temperature in the system is known to increase with increasing Lu concentration. Therefore, it is expected that the energy scale of the hybridization gap should increase wit...

We have carried out magneto-transport measurements for single crystal SrMnSb2. Clear Shubnikov-de Haas oscillations were resolved at relatively low magnetic field around 4 T, revealing a quasi-2D Fermi surface. We observed a development of quantized plateaus in Hall resistance (Rxy) at high pulsed f...
