Query: Unnormalized nonextensive expectation value and zeroth law of
  thermodynamics   We show an attempt to establish the zeroth law of thermodynamics within the
framework of nonextensive statistical mechanics based on the classic
normalization $\texttt{Tr}\hat{\rho}=1$ and the unnormalized expectation
$x=\texttt{Tr}\hat{\rho}^q\hat{x}$. The first law of thermodynamics and the
definition of heat and work in this formalism are discussed.
