Entanglement properties of ground states of many-body Hamiltonians is a subject of intense research. As a general feature, it has been observed that entanglement entropy of a subsystem is a sub-extensive quantity, in contrast with thermal entropy. We shall however introduce an effective (non-intensive) ground state temperature, enabling to recover a standard thermodynamic interpretation of entanglement entropy, and linking thermodynamic observables to each others in a standard way.
