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…
Emergence of the unexpected charge-density-wave phase driven by artificial gauge field in 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…
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…
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…
