The Influence of Perceived Ease of Use on Attitudes in using the GaYa Application in Creating a Social Enterprise in the Field of Fine Arts

Heribertus Himawan, D. P. Sari, Yohan Wismantoro, Ika Novita Dewi

Indonesian painters often encounter significant economic and social challenges, limiting their ability to exhibit work and access the art market. Virtual galleries (VGs) offer a promising avenue to overcome these barriers, with applications like GaYa designed to facilitate digital exhibitions and curation …

Field-Induced Criticality in YbCu4Au

Tomoya Taniguchi, Kiyoshi Osato, Hirotaka Okabe, T. Kitazawa et autres

YbCu4Au is a unique material exhibiting multiple quantum fluctuations simultaneously. In this study, we investigated the field-induced criticality in YbCu4Au, based on comprehensive micro and macro measurements, including powder X-ray diffraction (XRD), neutron powder diffraction (NPD), nuclear magnetic resonance, magnetization, resistivity, specific …

Formation of orbital molecules on a pyrochlore lattice induced by A-O\n bond covalency

A. Krajewska, A. Yaresko, J. Nuss, A. S. Gibbs et autres

The pyrochlore ruthenate In$_2$Ru$_2$O$_7$ displays a subtle competition\nbetween spin-orbital entanglement and molecular orbital formation. At room\ntemperature, a spin-orbit-entangled singlet state was identified. With\ndecreasing temperature, In$_2$Ru$_2$O$_7$ undergoes multiple structural\ntransitions and eventually forms a nonmagnetic ground state with semi-isolated\nRu$_2$O units on the pyrochlore lattice. …
