Query: Vacuum expectation value of the energy-momentum tensor in a higher
  dimensional compactified cosmic string spacetime   The main objective of this paper is to analyze the vacuum expectation value
(VEV) of the energy-momentum tensor (EMT) associated with a charged scalar
quantum field in a high-dimensional cosmic string spacetime admitting the
presence of a magnetic flux running along the string's core. In addition, we
also assume that the coordinate along the string's axis is compactified to a
circle and presents an extra magnetic flux running along its center. This
compactification is implemented by imposing a quasiperiodic condition on the
field with an arbitrary phase $\beta$. The calculation of the VEV of the EMT
and field squared, are developed by using the positive-energy Wightman
function. The latter is constructed by the mode sum of the complete set of
normalized bosonic wave-functions. Due to the compactification, two distinct
contributions take place. The first one corresponds to the VEV in a cosmic
string spacetime without compactification considering the magnetic interaction.
So, this term presents a contribution due to the non-trivial topology of the
conical space, and an additional contribution due to the interaction between
the scalar field with the magnetic flux. The latter is a periodic function of
the magnetic flux with period equal to the quantum flux, $\Phi_0=2\pi/e$, and
corresponds to a Aharanov-Bhom type contribution. The second contribution is
induced by the compactification itself and depends on the magnetic flux along
the string's core. It is also an even function of the magnetic flux enclosed by
the string axis. Some asymptotic expressions for the VEVs of the
energy-momentum tensor and field squared are provided for specific limiting
cases of the physical parameter of the model.
