Valence changes associated with the metal-insulator transition in BiLaNiO
H. Wadati, M. Takizawa, T. T. Tran +9
Perovskite-type BiNiO is an insulating antiferromagnet in which a charge disproportionation occurs at the Bi site. La substitution for Bi suppresses the charge disproportionati…
Flexible construction of hierarchical scale-free networks with general exponent
J. C. Nacher, N. Ueda, M. Kanehisa +1
Extensive studies have been done to understand the principles behind architectures of real networks. Recently, evidences for hierarchical organization in many real networks have al…
A `checkerboard' electronic crystal state in lightly hole-doped Ca_{2-x}Na_{x}CuO_{2}Cl_{2}
T. Hanaguri, C. Lupien, Y. Kohsaka +5
The phase diagram of hole-doped copper oxides shows four different electronic phases existing at zero temperature. Familiar among these are the Mott insulator, high-transition-temp…
Clustering under the line graph transformation: Application to reaction network
J. C. Nacher, N. Ueda, T. Yamada +2
Many real networks can be understood as two complementary networks with two kind of nodes. This is the case of metabolic networks where the first network has chemical compounds as…
NMR characterization of spin-1/2 alternating antiferromagnetic chains in the high-pressure phase of (VO)2P2O7
J. Kikuchi, K. Motoya, T. Saito +2
Local-susceptibility measurements via the NMR shifts of P and V nuclei in the high-pressure phase of (VO)PO confirmed the existence of a unique alte…
Two complementary representations of a scale-free network
J. C. Nacher, T. Yamada, S. Goto +2
Several studies on real complex networks from different fields as biology, economy, or sociology have shown that the degree of nodes (number of edges connected to each node) follow…
