Non-Fermi-Liquid Behaviors in Weakly Interacting Two-Dimensional Quasicrystals
Junmo Jeon, Shiro Sakai
Non-Fermi-liquid (NFL) behavior is usually associated with strong electronic correlations, quantum criticality, or singular fluctuations that invalidate the quasiparticle picture.…
Hyperuniform charge distributions and phase transitions in a generalized Aubry-André model
Lujia Xiang, Junmo Jeon, Shiro Sakai
We show the existence of distinct inhomogeneous charge distributions and a phase transition between them in aperiodic fermion systems. Using a generalized Aubry-André model as an…
Electron Model on Truchet Tiling: Extended-to-Localized Transitions, Mobility Edge, and Asymmetric Spectrum
Junmo Jeon, Shiro Sakai
Motivated by recent advances in the realization of Truchet-tiling structures in molecular networks and metal-organic frameworks, we investigate the wave localization issue in this…
Critical behavior of the Ising model on square-triangle tilings
Akihisa Koga, Shiro Sakai
We investigate magnetic properties of the ferromagnetic Ising model on square-triangle tilings to explore how the hyperuniformity, which characterizes long-range behavior of the po…
