Ultrafast observation of electron hybridization and in-gap states formation in Kondo insulator SmB6

Sanjay Adhikari, Yanjun Ma, Zachary Fisk +3

SmB6 is a promising candidate for topological Kondo insulator. In this letter, we report ultrafast carrier dynamics of SmB6. Two characteristic temperatures: T1=100 K and T2= 20 K…
