The electric structure of twisted bilayer GeSe, which shows a rectangular moir\'{e} pattern, is analyzed using $\bm{k}\cdot\bm{p}$ type effective continuum model. model constructed on the basis local approximation method, where lattice system approximated by its untwisted with parallel displacement, and required parameters are fixed help first-principles method. By inspecting twist angle depend...

Given ω ≥ 1, let Z2(ω) be the graph with vertex set Z 2 in which two vertices are joined if they agree in one coordinate and differ by at most ω in the other. (Thus Z2(1) is precisely Z .) Let pc(ω) be the critical probability for site percolation in Z2(ω). Extending recent results of Frieze, Kleinberg, Ravi and Debany, we show that limω→∞ ωpc(ω) = log(3/2). We also prove analogues of this resu...

We consider nanometer-sized fluid annuli (rings) deposited on a solid substrate and ask whether these rings break up into droplets due to the instability of Rayleigh-Plateau-type modified by the presence of the substrate, or collapse to a central drop due to the presence of azimuthal curvature. The analysis is carried out by a combination of atomistic molecular dynamics simulations and a contin...

The subject of research in this paper is RM-ODP, an ISO/ITU-T international standard. We investigate an important challenge that the standard faces, specifically the absence of a satisfactory formalization of its proposed conceptual framework. We report on the definition and implementation of a concrete resolution for this challenge: a single consistent formalization of the RM-ODP conceptual fr...

We show that, in the continuum limit, the dynamics of Hamiltonian systems defined on a lattice with long-range couplings is well described by the Vlasov equation. This equation can be linearized around the homogeneous state, and a dispersion relation, which depends explicitly on the Fourier modes of the lattice, can be derived. This allows one to compute the stability thresholds of the homogene...

Abstract In this paper, we present a novel universal coupled theory for metamaterial bound states in the continuum (BIC) or quasi-bound (quasi-BIC) which provides ultra-high Q resonance devices. Our analytically calculates coupling of two bright modes with phase information. method has much more accuracy ultra-strong comparing previous theories (the one mode and dark bright-mode coupling). Ther...
