Revisiting spin Hamiltonian parameters in a Kitaev material via Bayesian optimization of magnetization curves
Takahiro Misawa, Ryo Tamura, Kazuyoshi Yoshimi +1
Determining the spin Hamiltonian of a magnetic compound is crucial for understanding its magnetic properties. A standard approach is to derive model parameters from c…
Unified description of cuprate superconductors by fractionalized electrons emerging from integrated analyses of photoemission spectra and quasiparticle interference
Shiro Sakai, Youhei Yamaji, Fumihiro Imoto +6
Electronic structure of high-temperature superconducting cuprates is studied by analyzing experimental data independently obtained from two complementary spectroscopies, one, quasi…
Dome structure in pressure dependence of superconducting transition temperature for HgBaCaCuO -- Studies by low-energy effective Hamiltonian
Jean-Baptiste Morée, Youhei Yamaji, Masatoshi Imada
The superconducting (SC) cuprate HgBaCaCuO (Hg1223) has the highest K (the experimental SC transition temperature at optimal hole doping…
Ground state of the =1/2 pyrochlore Heisenberg antiferromagnet: A quantum spin liquid emergent from dimensional reduction
Rico Pohle, Youhei Yamaji, Masatoshi Imada
The quantum antiferromagnet on the pyrochlore lattice offers an archetypal frustrated system, which potentially realizes a quantum spin liquid characterized by the absence of stand…
