However, it is important to note that temperature gradients within the produced QGP can reach magnitudes of 100 MeV/fm, which is not small. Consequently, it remains uncertain whether the conventional hydrodynamic equation, based on the derivative expansion, can be reliably applied to the QGP. In this presentation, we will explore the effects arising from a potentially large temperature gradient by incorporating it to finite-temperature quantum field theory. Specifically, we will apply the imaginary-time formalism for local thermal equilibrium to the relativistic scalar field model to examine how temperature gradients influence thermodynamic properties such as the partition function and pressures.
