Abstract
An observer-dependent Hamiltonian is introduced. The vacuum state is defined by means of Hamiltonian diagonalization and minimization, which result to be equivalent criteria. This method encompasses a great number of known vacuum definitions, and works in an arbitrary geometry if the observer’s field satisfies certain properties.Keywords
