Irrationality Measure Controls Long-Wavelength Charge Fluctuations in Quasiperiodic Systems
Junmo Jeon, Shiro Sakai
Quasiperiodic order is characterized by irrational frequencies whose rational approximability known as irrationality measure defines distinct arithmetic classes. We establish that…
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 e…
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…
Hyperuniform properties of the square-triangle tilings
Akihisa Koga, Shiro Sakai, Yushu Matsushita +1
We study hyperuniform properties for the square-triangle tilings. The tiling is generated by a local growth rule, where squares or triangles are iteratively attached to its boundar…
Hyperuniformity in two-dimensional periodic and quasiperiodic point patterns
A. Koga, S. Sakai
We study hyperuniform properties in various two-dimensional periodic and quasiperiodic point patterns. Using the histogram of the two-point distances, we develop an efficient metho…
