Thermodynamics of a higher-order topological insulator
We investigate the order of the topological quantum phase transition in a two-dimensional quadrupolar topological insulator within a thermodynamic approach. Using numerical methods, we separate the bulk, edge, and corner contributions to the grand potential and detect different phase transitions in...
