The hexagonal lattice (sometimes called triangular lattice) is one of the five two-dimensional Bravais lattice types. [1] The symmetry category of the lattice is wallpaper group p6m. The primitive translation vectors of the hexagonal lattice form an …

In geometry, the triangular tiling or triangular tessellation is one of the three regular tilings of the Euclidean plane, and is the only such tiling where the constituent shapes are not parallelogons.

2023年6月2日 · Motivated by a recent experiment on WSe 2 / WS 2 moiré bilayers [Y. Tang et al., Nature (London) 579, 353 (2020)], which realized a triangular superlattice with a small hopping (of approximately 10 Kelvin), with tunable density of holes, we explore the Hubbard model on the triangular lattice for intermediate temperatures t ≲ T < U.

We consider iterative percolation defined on a triangular lattice of linear size L with periodic boundary conditions. Initially, at generation n = 0, each lattice site is sequen-tially visited and randomly colored white or black with a probability p = 1/2. Any nearest-neighbor sites of the same color are then connected to form percolation ...

Triangular lattice structures have been analyzed by many researchers [3-6]. Analytical solutions for investigating the effects of the local and global imperfections of longerons on the axial compressive strength of the lattice columns were performed by Crawford and Hedgepeth [3], Mikulas [4], and Crawford and Benton [5]. The

We study the folding of the regular triangular lattice in three dimensional embedding space, a model for the crumpling of polymerised membranes. We consider a discrete

2023年7月4日 · YbBO 3 is a member of the orthoborate family of materials which contains a triangular arrangement of Yb 3+ ions. Here we study the physical properties of YbBO 3 with neutron diffraction, inelastic neutron scattering, specific heat, and ac susceptibility measurements.

2022年9月23日 · Here, by combining TB modeling with first-principles calculations, we demonstrate the rich electronic structures of triangular lattice with multiple $(p_{x}, p_{y}, p_{z})$ orbitals. Type I/II Dirac point, quadratic nodal point and nodal-loops are observed, and the topological phase diagram is mapped out by manipulating the horizontal mirror ...

2021年9月13日 · By means of tunneling microscopy of the 2D bulk we identify the quantum spin Hall phase of this triangular lattice and unveil how a hidden honeycomb connectivity emerges from interference...
