Unlocking the general relationship between energy and entanglement spectra via the wormhole effect
Abstract Based on the path integral formulation of the reduced density matrix, we develop a scheme to overcome the exponential growth of computational complexity in reliably extracting low-lying entanglement spectrum from quantum Monte Carlo simulations. We test the method on the Heisenberg spin lad...
