Z-ACA ALLOTROPE: A TOPOLOGICAL CARBON MATERIAL WITH OBSTRUCTED WANNIER CHARGE CENTER, REAL TOPOLOGY, AND HINGE STATES

Z-ACA allotrope: a topological carbon material with obstructed Wannier charge center, real topology, and hinge states

As the most prevalent element on our planet, carbon manifests a wide variety of allotropic phases, significantly contributing to its complex physical properties.Recently, several carbon allotropes have been reported to possess abundant topological phases in theory and experiment.This work focuses on a sp3 carbon allotrope, Z-ACA allotrope, which co

H-infinity control of switched linear parabolic systems

The $H_{infty}$ control problem of a class of switched linear parabolic systems is considered.By applying the Desk multiple Lyapunov function method and the average dwell time scheme, sufficient conditions for exponential stability and the $H_{infty}$ control synthesis are established in terms of LMIs and a family of switching signals.The advantage
