Symmetry, topology, duality, chirality, and criticality in a spin-1/2 XXZ ladder with a four-spin interaction
Mateo Fontaine, Koudai Sugimoto, Shunsuke Furukawa
We study the ground-state phase diagram of a spin-1/2 XXZ model with a chirality-chirality interaction (CCI) on a two-leg ladder. This model offers a minimal setup to study an inte…
Pump-probe spectroscopy of the one-dimensional extended Hubbard model at half filling
Koudai Sugimoto, Satoshi Ejima
By utilizing time-dependent tensor-network algorithms in the infinite matrix-product-state representation, we theoretically investigate the pump-probe spectroscopy of the one-dimen…
Wannier-Stark ladders and Stark shifts of excitons in Mott insulators
Mina Udono, Tatsuya Kaneko, Koudai Sugimoto
External-field driven energy-level discretization, such as Landau quantization or Stark localization, is one of the most intriguing phenomena in quantum systems. We investigate the…
