Anomalous enhancement of Neel order in the square lattice Heisenberg model under fictitious magnetic field
Takayuki Yokoyama, Yasuhiro Tada
Fictitious magnetic fields can be introduced in quantum magnets by the strain engineering and the Aharonov-Casher effect. Here, we study impacts of a uniform fictitious magnetic fi…

Quantized polarization in a generalized Rice-Mele model at arbitrary filling
Yasuhiro Tada
We discuss the charge polarization in a generalized Rice-Mele model at arbitrary particle filling per site as a model of charge ordered systems in one dimension. The model possesse…

Impurity effects in one dimensional spin nematic liquid
Fumiya Nakamura, Yasuhiro Tada
We study impurity effects in the spin nematic phase of the - frustrated spin chain under an external magnetic field by using the infinite density matrix renormali…
