1. Octupole order in Ce 0.7 La 0.3 B 6 probed by resonant X-ray scattering The azimuthal angle dependence observed in the resonant X-ray scattering in phase IV of Ce 0.7 La 0.3 B 6 is analyzed theoretically[1]. It is shown that the peculiar angle dependence observed in the E2 channel is consistent with the Γ 5u-type octupole order with principal axis along(More)
This paper discusses a fully decentralized algorithm able to control the morphology of a two-dimensional modular robot called “Slimebot”, consisting of many identical modules, according to the environment encountered. One of the significant features of our approach is that we explicitly exploit “emergent phenomena” stemming from the(More)

This paper discusses a fully decentralized algorithm able to create a coherent swam of autonomous mobile robots from the viewpoint of “computational physics”. To this end, we particularly focus on the “Molecular Dynamics method” and the “Stokesian Dynamics method”, both of which are widely used to investigate multi-body systems. To verify the feasibility of(More)

We have succeeded in controlling tubular membrane formations in binary giant unilamellar vesicles (GUVs) using a simple temperature changing between the homogeneous one-phase region and the two-phase coexistence region. The binary GUV is composed of inverse-cone (bulky hydrocarbon chains and a small headgroup) and cylinder-shaped lipids. When the(More)
