Local wave-packet spectroscopy of the Drude weight in Tomonaga-Luttinger liquids
Takayuki Yokoyama, Yasuhiro Tada
We investigate wave packets generated by a local pulse electric field in a Tomonaga-Luttinger liquid (TLL) with a U(1) charge . Bosonization shows that a local pulse field creat…
Evidence for interior-gap pair-density-wave state in Kondo-Heisenberg chains
Yuto Hirose, Shunsuke C. Furuya, Yasuhiro Tada
Interior-gap superconductivity has long been discussed as an exotic paired state in the presence of Fermi-surface mismatch, but its realization in canonical strongly correlated mod…
Artificial-gauge-field-driven reentrant charge-density-wave phase in a three-leg Bose-Hubbard ladder
Takayuki Yokoyama, Yasuhiro Tada
We investigate hard-core bosons at half filling on a three-leg ladder under the uniform artificial gauge field. By analyzing current patterns and correlation functions, we uncover…
Spin nematic order and superconductivity in - Kondo lattice model on square lattice
Sho Uraga, Yasuhiro Tada
We investigate competition and cooperation of magnetic frustration and the Kondo effect in the - Kondo lattice model on the square lattice at zero temperature. In this mo…
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…
