Webhyperbolic geodesic through τ ∈ H. Since no complete geodesic can be entirely contained in a horoball, A·Lτ must meet W, and therefore a·L is well-rounded for some a ∈ A. Figure 1. The well-rounded spine for SL 2(Z). The well-rounded lattices in Rn also form a compact spine for the space SOn(R)\SLn(R)/SLn(Z), Weborder topological insulator model in hyperbolic lattices by breaking the time-reversal symmetry (TRS) of quan-tum spin Hall insulators. We investigate three kinds of … WebHere, we demonstrate both in theory and experiment that exotic topological states can exist in engineered hyperbolic lattices with unique properties compared to their Euclidean counterparts. Based on the extended Haldane model, the boundary-dominated first-order Chern edge state with a nontrivial real-space Chern number is achieved. irish philosopher quotes
