Exactly solvable spin chain models corresponding to BDI class of topological superconductors
We present an exactly solvable extension of the quantum XY chain with longer range multi-spin interactions. Topological phase transitions of the model are classified in terms of the number of Majorana zero modes, n(M) which are in turn related to an integer winding number, n(W). The present class of...
