Observation of complex orbital order in MnV2O4
Chihaya Koyama, Shunsuke Kitou, Taishun Manjo +8
Orbital ordering in vanadium spinel oxides with a geometrically frustrated pyrochlore structure has been a subject of controversy, owing to competing theoretical models and the abs…
Observation of g-wave altermagnetic multipole
Ryo Misawa, Rikuto Oiwa, Shunsuke Kitou +16
Over the past few years, altermagnets have emerged as a new class of collinear magnets with broken time-reversal symmetry, offering novel opportunities for spintronics beyond conve…
Probing the Dynamical Structure Factor of Quantum Spin Chains via Low-Temperature Gibbs States with Matrix Product State Subspace Expansion
Tomoya Takahashi, Wei-Lin Tu, Ji-Yao Chen +1
Studying finite-temperature properties with tensor networks is notoriously difficult, especially at low temperatures, due to the rapid growth of entanglement and the complexity of…
Luttinger surface and exchange splitting induced by ferromagnetic fluctuations
Motoharu Kitatani, Yusuke Nomura, Shiro Sakai +1
Ferromagnetism in the single-orbital Hubbard model, which contains only local Coulomb repulsion and no explicit ferromagnetic exchange interactions, has been extensively studied. H…
Ab initio study on heavy-fermion behavior in LiVO: Role of Hund's coupling and stability
Steffen Backes, Yusuke Nomura, Ryotaro Arita +1
LiVO is a member of the so-called heavy fermion compounds, with effective electron mass exceeding 60 times the free electron mass, comparable to heavy fermion com…
Quantum many-body solver using artificial neural networks and its applications to strongly correlated electron systems
Yusuke Nomura, Masatoshi Imada
With the evolution of numerical methods, we are now aiming at not only qualitative understanding but also quantitative prediction and design of quantum many-body phenomena. As a no…
