Description:
Author(s): Lars Bonnes, Hannes Pichler, and Andreas M. Läuchli We study the Renyi entropy in the finite-temperature crossover regime of a Hubbard chain using quantum Monte Carlo. The ground-state entropy has characteristic features such as a logarithmic divergence with block size and 2 k F oscillations that are a hallmark of its Luttinger liquid nature. The inter... [Phys.
