Figure 2: Phase diagram of a graphene integer QHPF.
From: Modulated phases of graphene quantum Hall polariton fluids
White (grey-shaded) regions represent the values of the detuning Δ—in units of g—and density nX of total excitations at which the homogeneous phase described by equations (17, 18, 19) is stable (unstable). (a) κr=5 and M=1; (b) κr=5 and M=2; (c) κr=15 and M=1; and (d) κr=15 and M=2. In each panel, blue lines denote the location of points in the plane (Δ/g,nX), where the ratio between the number of excitons and the number of photons is constant: nex/nph=1/10 (dashed line), nex/nph=1 (dash-dotted line) and nex/nph=10 (dotted line). These curves have been calculated with reference to the homogenous phase.
