Fig. 5: Energy spectra for the bilayer topological system with the same periodically modulated on-site potentials.
From: Simulating Chern insulators on a superconducting quantum processor
a–c Energy spectra versus ϕ of a finite ladder with 30 sites for the same modulated amplitudes Δ↑/2π = Δ↓/2π = 12 MHz with J⊥/2π = 1 MHz (a), J⊥/2π = 7 MHz (b), and J⊥/2π = 15 MHz (c). Other parameters used are J∥/2π = 8 MHz, \({J}_{\parallel }^{{\prime} }=0.1{J}_{\parallel }\), and J× = 0.2J∥.
