摘要: We investigate the finite-size corrections of entanglement entropy critical ladders and propose a conjecture for its scaling behaviour. The is verified free fermions, Heisenberg ladders, quantum Ising ladders. Our results support that prefactor logarithmic correction ladder models universal associated with central charge one-dimensional version number branches gapless excitations. suggest it possible to infer whether there violation entropic area law in two-dimensional systems by analyzing behaviour systems, which are easier deal with.
