Here, the dispersion relation is calculated using the parameters in Fig. So we realize a second-order topological insulator in the quasienergy-0 gap, and a Weyl semimetal in the quasienergy- π / T gap. Due to the topological charge of the Weyl point, Weyl semimetals can be sliced into a family of two-dimensional (2D) Chern and normal insulators parametrized by k z. The existence of Weyl points indicates the formation of a Weyl semimetal phase at the π / T gap. With the introduction of perturbation, two three-dimensional bands with a linear dispersion are degenerate at two isolated momentum points, which are called Weyl points. So we believe that there is a higher-order topological phase at this gap. Play Phase 10 for free and online at Kizi now Complete the level's objectives by creating sets and empty out. According to topological classification, the higher-order topological number can be defined. In Phase 10, it's time to challenge other players with the amazing cards in your hand Offering fun and challenging gameplay to players, get ready to turn the tables and earn points in this game. As shown in (a), the band gap labeled in cyan color indicates that there are gapless chiral hinge states in this gap.

Phase 0 is depolarization of the membrane and the opening of 'fast' (i.e., high-flow) sodium channels.

Schematic of (a) an anomalous Floquet higher-order topological insulator and (b) a composite topological phase. There are five cardiac action potential phases, numbered 0 through 4 (scientists get strange ideas sometimes).
