Higher-Order Topological Phases on Quantum Fractals
[article]
2021
arXiv
pre-print
These predictions can be experimentally tested on designer electronic fractal materials, as well as on various highly tunable metamaterial platforms, such as photonic and acoustic lattices. ...
Here we theoretically show that a special class of crystalline, namely higher-order topological phases that via an extended bulk-boundary correspondence feature robust gapless modes on lower dimensional ...
Here, we focus only on the local or on site pairings which are oblivious to the underlying lattice structure, and thus possess natural immunity against the lack of crystalline order. ...
