Low-energy photoexcitations inside the Mott gap in doped Hubbard and t-J ladders

Sumal Chandra, Kazuya Shinjo, Shigetoshi Sota +2

We investigate changes in the optical conductivity of doped Mott insulators by tuning ultrashort pump pulses to target either the Drude or low-energy absorption regions. Using a ho…
