Fig. 2: Entanglement spectrum and susceptibility for ϕ/π < 0.5.
From: Twice hidden string order and competing phases in the spin-1/2 Kitaev–Gamma ladder
iDMRG results for: a Entanglement spectrum from ρA, red dashed line in Fig. 1a. b Entanglement spectrum from ρB, blue dashed line in Fig. 1a. The numbers refer to the degeneracy of the eigenvalue. c \({\chi }_{\phi }^{e}\). Two distinct phases, SPTα and SPTβ, are visible between the FM\({}_{{U}_{6}}\) and AΓ phase. The red shading between ϕ/π = 0.428-0.442 denotes a transitional region of limited convergence due to a field instability.
