Abstract
The high-pressure melting curve of iron is of major importance to the Earth's sciences, as it provides a close estimate of the temperature of
the Earth's core. Despite being studied experimentally for more than a decade and, more recently, using theoretical quantum mechanics
techniques, there are still large discrepancies between different groups. In this article, we will describe our theoretical approach to the
problem and discuss the reason of the discrepancies with other theoretical calculations.

1. Introduction
The thermodynamic properties of iron, and in particular
its high-pressure melting curve, have been the subject of
intense investigation in the past few decades. The reason
for this substantial interest is that iron is most certainly the
main constituent of the Earth's core, therefore, by knowing
