Figure 3From: Trapped-ion quantum simulation of tunable-range Heisenberg chainsEntanglement entropy. We plot the entanglement entropy of the ionic system with N=18 for detuning δ=1kHz and δ=100kHz, and for ideal Heisenberg chains with open boundary conditions and nearest-neighbor interactions (NN) and Majumdar-Ghosh (MG) interactions.Back to article page
