Prominent electron-hole asymmetry in thermoelectric transport of LaCoO
Ryuji Okazaki, Keisuke Tomiyasu
We have measured the electrical resistivity and the thermopower of the electron-doped perovskite cobaltites LaCoTeO. In contrast to the hole-doped systems such as m…
Spin dynamics simulation of the -vortex fluctuations
Yo P. Mizuta, Kazuki Aoyama, Keisuke Tomiyasu +2
Motivated by the recent quasi-elastic neutron scattering experiment, we extend the spin-dynamics simulation on the triangular-lattice Heisenberg antiferromagnet, to observe a sharp…
Observation of topological vortex fluctuations in the frustrated Heisenberg magnet NaCrO
K. Tomiyasu, Y. P. Mizuta, M. Matsuura +2
Spin fluctuations in the triangular-lattice Heisenberg antiferromagnet NaCrO are investigated by means of quasi-elastic neutron scattering with high energy resolution and wide…
A Sufficient Statistic for Influence in Structured Multiagent Environments
Frans A. Oliehoek, Stefan Witwicki, Leslie P. Kaelbling
Making decisions in complex environments is a key challenge in artificial intelligence (AI). Situations involving multiple decision makers are particularly complex, leading to comp…
Color theorems, chiral domain topology and magnetic properties of FexTaS2
Yoichi Horibe, Junjie Yang, Yong-Heum Cho +8
Common mathematical theory can have profound applications in understanding real materials. The intrinsic connection between aperiodic orders observed in the Fibonacci sequence, Pen…
Direct observation of the proliferation of ferroelectric loop domains and vortex-antivortex pairs
S. C. Chae, N. Lee, Y. Horibe +5
We discovered "stripe" patterns of trimerization-ferroelectric domains in hexagonal REMnO3 (RE=Ho, ---, Lu) crystals (grown below ferroelectric transition temperatures (Tc), reachi…
