WebBulk-edge correspondence revisited ..... 51 6.2. Noncommutative geometry ..... 53 1. Introduction Topological insulators [41] are new materials observed in nature which behave like insulators in the bulk but have conducting edge or surface states on the boundary. In physical terms, topological insulators are gapped electronic systems which show ... WebJun 10, 2024 · Such a picture is the first-order of topological insulators and obeys the general bulk–edge correspondence . The topological insulators based on graphene plasmonics are investigated in various platforms [33,34,35,36,37,38,39].

WebApr 11, 2024 · According to the AdS/CFT correspondence, the geometries of certain spacetimes are fully determined by quantum states that live on their boundaries — indeed, by the von Neumann entropies of portions of those boundary states.This work investigates to what extent the geometries can be reconstructed from the entropies in polynomial … WebJan 23, 2024 · Due to its dependence on the real-space origin and unit cell, however, there is an ambiguity in its use in a bulk-boundary correspondence. Here, we extract an origin-independent part of γ, the so-called intercellular Zak phase γinter, and show that it is a bulk quantity that unambiguously predicts the number of surface modes.
WebBackground: Bulk-Boundary Correspondence and Floquet Systems. First, it's necessary to review the topological classification for static systems that gives rise to chiral edge states. Single-particle theory gives rise to band theory and corresponding energy bands. If these bands are separated from one another by an energy gap, then each band can ...
