Abstract
The zeta function of a number field can be interpreted as the partition
function of an associated quantum statistical mechanical (QSM) system, built from
abelian class field theory.
We introduce a general notion of isomorphism of QSM-systems and prove that it
preserves (extremal) KMS equilibrium states.
We prove that two number fields with isomorphic quantum statistical mechanical
systems are arithmetically equivalent, i.e., have the same zeta function. If one of
the fields is normal over Q, this implies that the fields are isomorphic. Thus, in this
case, isomorphism of QSM-systems is the same as isomorphism of number fields,
and the noncommutative space built from the abelianized Galois group can replace
the anabelian absolute Galois group from the theorem of Neukirch and Uchida.
