Fig. 3: Observation of Wilson loop spectra and entanglement spectra.

From: Quantum simulation for topological Euler insulators

Fig. 3

a, b The experimentally measured Wilson loop spectra (solid circles) in comparison with the numerically calculated ones (solid lines). c, d The experimentally measured entanglement spectra (circles) in comparison with the numerical ones (solid lines). We consider the nontrivial Euler Hamiltonian H(k) in Eq. (1) with m = 1 in a, c and the trivial one with m = 3 in b, d.
