downfolding based on the GW approximation for infinite-layer nickelates
Motoaki Hirayama, Yusuke Nomura, Ryotaro Arita
We derive an effective three-orbital model for the infinite-layer nickelates based on the band structure obtained by the GW approximation (GWA), where we consider the Ni 3$d_{x^2-y…
Investigating Network Parameters in Neural-Network Quantum States
Yusuke Nomura
Recently, quantum-state representation using artificial neural networks has started to be recognized as a powerful tool. However, due to the black-box nature of machine learning, i…
Fully filling-controlled pyrochlore ruthenates: emergent ferromagnetic-metal state and geometrical Hall effect
Ryoma Kaneko, Kentaro Ueda, Shiro Sakai +4
Carrier doping to the Mott insulator is essential to produce highly correlated metals with emergent properties. Pyrochlore ruthenates, PrRuO (Ru- electron num…
Purifying Deep Boltzmann Machines for Thermal Quantum States
Yusuke Nomura, Nobuyuki Yoshioka, Franco Nori
We develop two cutting-edge approaches to construct deep neural networks representing the purified finite-temperature states of quantum many-body systems. Both methods commonly aim…
Geometrical Hall effect and momentum-space Berry curvature from spin-reversed band pairs
Max Hirschberger, Yusuke Nomura, Hiroyuki Mitamura +10
When nanometric, noncoplanar spin textures with scalar spin chirality (SSC) are coupled to itinerant electrons, they endow the quasiparticle wavefunctions with a gauge field, terme…
Magnetic exchange coupling in cuprate-analog nickelates
Yusuke Nomura, Takuya Nomoto, Motoaki Hirayama +1
Motivated by the recent discovery of superconductivity in doped NdNiO, we study the magnetic exchange interaction in layered nickelates from first principles. The mot…
