Quantized Berry winding from an emergent $\mathcal{PT}$ symmetry
Abstract
Linear crossings of energy bands occur in a wide variety of materials. In this paper we address the question of the quantization of the Berry winding characterizing the topology of these crossings in dimension D=2 D = 2 . Based on the historical example of 2
