Scaling behavior in a multicritical one-dimensional topological insulator
M. Malard, H. Johannesson, W. Chen
A class of Aubry-André-Harper models of spin-orbit coupled electrons exhibits a topological phase diagram where two regions belonging to the same phase are split up by a multicriti…

Multicriticality in a one-dimensional topological band insulator
Mariana Malard, David Brandao, Paulo Eduardo de Brito +1
A central tenet in the theory of quantum phase transitions (QPTs) is that a nonanalyticity in the ground-state energy in the thermodynamic limit implies a QPT. Here we report on a…
