Localized states of the non-Hermitian Schr{ö}dinger equation with a complex $1/ r^{2}$ potential: from Efimov states to bipolarons

Kyoka Tsunoda, Kazuki Yamamoto, Shimpei Endo

We study the non-Hermitian Schrödinger equation with a complex $1/ r^{2}$ potential, which bridges Hermitian few-body and non-Hermitian many-body physics: a real attractive potentia…

Efficiency of Continuous-Time Quantum Monte Carlo Updates in the Ferromagnetic State of the Doped SU(3) Fermi-Hubbard Model

Juntaro Fujii, Kazuki Yamamoto, Akihisa Koga

We investigate the sampling efficiency in a segment-based continuous-time hybridization-expansion quantum Monte Carlo solver within dynamical mean-field theory for the doped SU(3)…

Impact of Stealthy Hyperuniform Magnetic Impurity Configurations on Bulk Magnetism in a Two-dimensional Heisenberg Model

K. Asakura, K. Yamamoto, A. Koga

We investigate an antiferromagnetic quantum Heisenberg model on a square lattice with high-spin magnetic impurities to clarify how random and stealthy hyperuniform impurity configu…
