The von Neumann entropy asymptotics in multidimensional fermionic systems

Farkas, S. Zimbora?s, Z.

We study the von Neumann entropy asymptotics of pure translation-invariant quasifree states of d-dimensional fermionic systems. It is shown that the entropic area law is violated by all these states: apart from the trivial cases, the entropy of a cubic subsystem with edge length L cannot grow slower than L(d-1) ln L. As for the upper bound of the entropy asymptotics, the zero-entropy-density property of these pure states is the only limit: it is proven that arbitrary fast sub-L(d) entropy growth is achievable.

On the sharpness of the zero-entropy-density conjecture

Farkas, S. Zimbora?s, Z.

The zero-entropy-density conjecture states that the entropy density defined as s:=lim NrarrinfinS N/N vanishes for all translation-invariant pure states on the spin chain. Or equivalently, S N, the von Neumann entropy of such a state restricted to N consecutive spins, is sublinear. In this paper it is proved that this conjecture cannot be sharpened, i.e., translation-invariant states give rise to arbitrary fast sublinear entropy growth. The proof is constructive, and is based on a class of states derived from quasifree states on a CAR algebra. The question whether the entropy growth of pure quasifree states can be arbitrary fast sublinear was first raised by Fannes et al. [J. Math. Phys. 44, 6005 (2003)]. In addition to the main theorem it is also shown that the entropy asymptotics of all pure shift-invariant nontrivial quasifree states is at least logarithmic
