Matrix product states for critical spin chains: finite size scaling versus finite entanglement scaling

B. Pirvu, G. Vidal, F. Verstraete +1

We investigate the use of matrix product states (MPS) to approximate ground states of critical quantum spin chains with periodic boundary conditions (PBC). We identify two regimes…
