-symmetry as Effective Time Reversal Symmetry for Anderson Localization in a Collinear Antiferromagnet

Kim-Khuong Huynh, Takuma Ogasawara, Motoi Kimata +7

We show that -symmetry acts as the effective time-reversal symmetry governing Anderson localization in the antiferromagnet BaMnBi, whereas the general time-re…

Supercritical fluid of quantum electrons in three-dimensional superconducting fullerides

Xinying Li, Yuki Matsuda, Chongli Yang +10

The supercritical fluid (SCF) of quantum electrons at the Mott metal-insulator transition without symmetry breaking is one of the most elusive phenomena in strongly correlated elec…

Longitudinal magneto-thermal conductivity and magneto-Seebeck of itinerant antiferromagnetic BaMnBi

Takuma Ogasawara, Hailiang Xia, Khuong-Kim Huynh +8

Thermal transport, generally mediated by the direct microscopic exchange of kinetic energy via lattice phonons, can also be modified by contributions from additional quasiparticles…

Insulator-to-metal Mott transition facilitated by lattice deformation in monolayer -RuCl on graphite

Xiaohu Zheng, Ogasawara Takuma, Huaxue Zhou +7

Creating heterostructures with graphene/graphite is a practical method for charge-doping -RuCl, but not sufficient to cause the insulator-to-metal transition. In this study,…

Magnetic-field-induced Anderson localization in orbital selective antiferromagnet BaMnBi

Takuma Ogasawara, Kim-Khuong Huynh, Stephane Yu Matsushita +6

We report a metal-insulator transition (MIT) in the half-filled multiorbital antiferromagnet (AF) BaMnBi that is tunable by a magnetic field perpendicular to the AF sublatt…

Large negative magnetoresistance in BaMnBi antiferromagnet

Takuma Ogasawara, Kim-Khuong Huynh, Time Tahara +7

A very large negative magnetoresistance (LNMR) is observed in the insulating regime of the antiferromagnet BaMnBi when a magnetic field is applied perpendicular to the dire…

Itinerant antiferromagnetic BaMnPn's showing both negative and positive magnetoresistances

Kim-Khuong Huynh, Takuma Ogasawara, Keita Kitahara +7

We report the discovery of a novel giant magnetoresistance (GMR) phenomenon in a family of BaMnPn antiferromagnets (Pn stands for P, As, Sb, and Bi) with a parity-time…
