WebMay 12, 2024 · (B) Measured edge-state occupation ratio at the end of the 150-mm-long sample. (C) Quasi-energies outside the topological gap allow light to diffract deep into the lattice. (D) By contrast, excitations within the gap yield a pronounced population of the topological edge state near the resonant angle of excitation. A certain leakage into the ... WebDec 31, 2024 · Chiral edge states are a hallmark feature of two-dimensional topological materials. Such states must propagate along the edges of the bulk either clockwise or counterclockwise, and thus produce oppositely propagating edge states along the two parallel edges of a strip sample. However, recent theories have predicted a …

WebNov 14, 2024 · The standard state transfer protocol is adapted to make it robust against dispersive and disorder effects and to realise quantum state transfer between distant qubits using the chiral edge states of a two-dimensional topological spin system. WebOct 13, 2024 · As we know in particle physics, chirality corresponds to eigenvalues of the fifth gamma matrix, and helicity corresponds to the value of the projection of spin onto momentum. So in condensed matter physics, are they the same as the particle-physics definition? And how does one distinguish chiral states from helical states? quantum … WebJun 20, 2024 · of chiral states is given by the sum over the Chern num-ber of all occupied bands. Evaluating the Chern num-bers of all of the bands in the band structure is then su cient for completely understanding the behavior of edge states, and nontrivial Chern numbers are required to observe chiral edge states.
