DOI: 10.1038/s42005-019-0247-0

Abstract: Tuning the electronic properties of a matter is of fundamental interest in scientific research as well as in applications. Recently, the Mott insulator-metal transition has been reported in a pristine layered transition metal dichalcogenide 1T-TaS$${}_{2}$$2,… read more here.

Published in 2017 at "Physical Review B"

DOI: 10.1103/physrevb.96.195141

Abstract: We theoretically investigate pump-probe optical responses in the two-dimensional extended Hubbard model describing cuprates by using a time-dependent Lanczos method. At half filling, pumping generates photoinduced absorptions inside the Mott gap. A part of low-energy… read more here.
