Temperature dependence of charge-to-spin conversion in rhombohedral (110) bismuth thin film
K. Tatsuoka, N. Fukumoto, S. Sakamoto +7
The amplitude of charge-to-spin conversion, namely the spin Hall effect (SHE), in bismuth (Bi) strongly depends on its crystal orientation. The conversion efficiency at room temper…
Survival of the metallic state in a single-hole multiband -orbital molecular system
Keisuke Matsui, Ryan A. Klein, Naoya Yoshikane +14
Strong correlations and ferromagnetic Hund's coupling lead to diverse electronic phenomena in transition-metal oxides that sensitively depend on the -orbital electron filling. F…
Optical vortex probe of loop-current chirality in moiré materials

GW240925 and GW250207 are two loud gravitational-wave signals from binary black hole coalescences observed with network signal-to-noise ratios and , respectively…
UCd: A strongly localized 5 material
Martin Sundermann, Naoki Ito, Daisuke Takegami +11
UCd is an antiferromagnetic uranium intermetallic compound ( = 5.3K) with enhanced electron mass and uranium-uranium spacings nearly twice the Hill limit, suggest…
Searches for Continuous Gravitational Waves from Supernova Remnants in the first part of the LIGO-Virgo-KAGRA Fourth Observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1764
We present results from directed searches for continuous gravitational waves from a sample of 15 nearby supernova remnants, likely hosting young neutron star candidates, using data…
Anomalous waiting-time distributions in postselection-free quantum many-body dynamics under continuous monitoring
Kazuki Yamamoto, Ryusuke Hamazaki
We investigate waiting-time distributions (WTDs) of quantum jumps in continuously monitored quantum many-body systems, whose unconditional dynamics lead to the trivial infinite-tem…
