Absence of diffusion and fractal geometry in the Holstein model at high temperature
Chen-Yen Lai, S. A. Trugman
We investigate the dynamics of an electron coupled to dispersionless optical phonons in the Holstein model, at high temperatures. The dynamics is conventionally believed to be diff…
Ultrafast X-ray Absorption Spectroscopy of Strongly Correlated Systems: Core Hole Effect
Chen-Yen Lai, Jian-Xin Zhu
In recent years, ultrafast pump-probe spectroscopy has provided insightful information about nonequilibrium dynamics of excitations in materials. In a typical experiment of time-re…
Correlated Phases of Population Imbalanced Fermi-Fermi Mixtures on an Optical Lattice
Chen-Yen Lai, Chuntai Shi, Shan-Wen Tsai
We study a two species fermion mixture with different populations on a square lattice modeled by a Hubbard Hamiltonian with on-site inter-species repulsive interaction. Such a mode…
Field Induced Spin Supersolidity in Frustrated Spin-1/2 Spin-Dimer Models
Pochung Chen, Chen-Yen Lai, Min-Fong Yang
By means of the recently developed algorithm based on the tensor product states, the magnetization process of frustrated spin-1/2 spin-dimer models on a square lattice is investiga…
Numerical Study of Spin-1/2 XXZ Model on Square Lattice from Tensor Product States
Pochung Chen, Chen-Yen Lai, Min-Fong Yang
By means of the recently proposed algorithm based on the tensor product states, the magnetization process of the spin-1/2 anti-ferromagnetic XXZ model on a square lattice is invest…
Interaction-induced first order correlation between spatially-separated 1D dipolar fermions
Chi-Ming Chang, Wei-Chao Shen, Chen-Yen Lai +2
We calculate the ground-state properties of fermionic dipolar atoms or molecules in a one-dimensional double-tube potential by using the Luttinger liquid theory and the density mat…
