Theory of Fractionally-magnetized Quantum Ferromagnet
Isao Maruyama, Shin Miyahara
We present a theory to realize entangled quantum spin states with fractional magnetization. The origin of magnetization reduction is partly emergent antiferromagnetism, that is, sp…
Flat-band solutions in -dimensional decorated diamond and pyrochlore lattices: Reduction to molecular problem
Tomonari Mizoguchi, Hosho Katsura, Isao Maruyama +1
Flat-band models have been of particular interest from both fundamental aspects and realization in materials. Beyond the canonical examples such as Lieb lattices and line graphs, a…
Fractionally quantized Berry phases of magnetization plateaux in spin- Heisenberg multimer chains
Isao Maruyama, Shin Miyahara
We study the fractionally quantized Berry phase, , to characterize local -mer spin structures at magnetization pl…
Determination of Tomonaga-Luttinger parameters for a two-component liquid
Olabode M. Sule, Hitesh J. Changlani, Isao Maruyama +1
We provide evidence for the mapping of critical spin-1 chains, in particular the SU(3) symmetric bilinear-biquadratic model with additional interactions, to free boson theories usi…
Magnetic correlation effects by the topological zero mode in a hydrogenated graphene vacancy
Naoki Morishita, Gagus Ketut Sunnardianto, Koichi Kusakabe +3
Electron correlation effects caused by the topological zero mode of a hydrogenated graphene vacancy, , with three adsorbed hydrogen atoms is discussed theoretically. A Kon…
Orbital mixture effect on the Fermi surface- correlation in the cuprate superconductors --- bilayer vs single layer
Hirofumi Sakakibara, Katsuhiro Suzuki, Hidetomo Usui +6
By constructing two-orbital models from first principles, we have obtained a systematic correlation between the Fermi surface warping and the evaluated …
