Nonlocal Kondo-exchange-driven intrinsic anomalous Hall effect in localized- antiferromagnetic metals
Akimitsu Kirikoshi, Junya Otsuki
The anomalous Hall effect in antiferromagnetic metals has attracted considerable attention. Most known realizations involve itinerant electrons that simultaneously mediate char…
Magneto-optical imaging of macroscopic altermagnetic domains in MnTe
Gakuto Watanabe, Soichiro Yamane, Ryotaro Maki +6
Altermagnets are a new class of magnets accompanying global time-reversal symmetry breaking (TRSB) without net magnetization. The TRSB results in formation of novel altermagnetic d…
Multipolar fluctuations from localized 4f electrons in CeRh2As2
Koki Numa, Eri Matsuda, Akimitsu Kirikoshi +1
The heavy-fermion superconductor CeRh2As2 exhibits a non-superconducting phase transition that precedes the emergence of superconductivity. The nature of the corresponding order pa…
From localized 4f electrons to anisotropic exchange interactions in ferromagnetic CeRh6Ge4
Shoichiro Itokazu, Akimitsu Kirikoshi, Harald O. Jeschke +1
CeRh6Ge4 is a cerium-based ferromagnetic material exhibiting a quantum critical behavior under pressure. We derive effective exchange interactions, using the framework of density f…
Robust analytic continuation using sparse modeling approach imposed by semi-positive definiteness for multi-orbital systems
Yuichi Motoyama, Hiroshi Shinaoka, Junya Otsuki +1
Analytic continuation (AC) from imaginary-time Green's function to spectral function is essential in the numerical analysis of dynamical properties in quantum many-body systems. Ho…
Spin-Orbital Ordering in Alkali Superoxides
Kohei Shibata, Makoto Naka, Harald O. Jeschke +1
Akali superoxides AO2 (A=Na, K, Rb, Cs), due to an open p shell of the oxygen ion O2^- with degenerate pi orbitals, have spin and orbital degrees of freedom. The complex magnetic,…
Anomalously large spin-dependent electron correlation in nearly half-metallic ferromagnet CoS
Hirokazu Fujiwara, Kensei Terashima, Junya Otsuki +19
The spin-dependent band structure of CoS which is a candidate for a half-metallic ferromagnet was investigated by both spin- and angle-resolved photoemission spectroscopy and t…
Compressed Sensing of Compton Profiles for Fermi Surface Reconstruction: Concept and Implementation
J. Otsuki, K. Yoshimi, Y. Nakanishi-Ohno +3
Compton scattering is a well-established technique that can provide detailed information about electronic states in solids. Making use of the principle of tomography, it is possibl…
Multipolar ordering from dynamical mean field theory with application to CeB6
J. Otsuki, K. Yoshimi, H. Shinaoka +1
Magnetic and multipolar ordering in f electron systems takes place at low temperatures of order 1--10 Kelvin. Combinations of first-principles with many-body calculations for such…
