Description
Finite-size effects are usually taken into account in effective field theoretical models via constraints of the momentum space. This could be either discretization due to the finite spatial extent with modes determined by the boundary condition or a simple low momentum cutoff. We implemented both scenarios by applying different boundary conditions and we studied, how the treatment of the vacuum contribution affects the finite volume effects on the phase diagram and the thermodynamic quantities. A strong dependence was found on the momentum space modification and the vacuum term, which explains certain differences between previous results and highlights the importance of the scheme used in the calculations.
