Topological phases of one-dimensional fermions: An entanglement point of view
Topological phases of one-dimensional fermions: An entanglement point of view
The effect of interactions on topological insulators and superconductors remains, to a large extent, an open problem. Here, we describe a framework for classifying phases of one-dimensional interacting fermions, focusing on spinless fermions with time-reversal symmetry and particle number parity conservation, using concepts of entanglement. In agreement with an example …
