Photoinduced Dynamics of Commensurate Charge Density Wave in 1T-TaS Based on Three-Orbital Hubbard Model
Tatsuhiko N. Ikeda, Hirokazu Tsunetsugu, Kenji Yonemitsu
We study the coupled charge-lattice dynamics in the commensurate charge density wave (CDW) phase of the layered compound 1T-TaS driven by an ultrashort laser pulse. For descr…
Floquet-Theoretical Formulation and Analysis of High-Harmonic Generation in Solids
Tatsuhiko N. Ikeda, Koki Chinzei, Hirokazu Tsunetsugu
By using the Floquet eigenstates, we derive a formula to calculate the high-harmonic components of the electric current (HHC) in the setup where a monochromatic laser field is turn…
Exploring the Kondo model in and out of equilibrium with alkaline-earth atoms
Márton Kanász-Nagy, Yuto Ashida, Tao Shi +6
We propose a scheme to realize the Kondo model with tunable anisotropy using alkaline-earth atoms in an optical lattice. The new feature of our setup is Floquet engineering of inte…
Revisiting the Floquet-Bloch theory for an exactly solvable model of one-dimensional crystals in strong laser fields
Tatsuhiko N. Ikeda
We revisit the Floquet-Bloch eigenstates of a one-dimensional electron gas in the presence of the periodic Kronig-Penny potential and an oscillating electric field. Considering the…
