The fundamental physics underlying the properties of many technologically important materials is the fact that electrons do not ignore one another but correlate their motion to avoid each other. Correlation effects can lead to surprising emergent properties, such as superconductivity, where current flows with no resistance due to the fact that electrons travel in pairs in a very robust way, not hindered by defects or imperfections invariably present in real materials.
My recent scientific focus has been to experimatally investigate the electronic properties of the newly discovered iron-based superconductors. While future scientific endeavor is difficult to predict in advance, superconductivity is one of the most exciting phenomena and has the potential to change significantly our way of life with applications in energy storage and transport (reducing dramatically the energy cost as the current flows without resistance), in medical investigations (as the case of MRI machines) or high speed trains (like the bullet train in Japan). To answer the feasibility of room temperature superconductivity requires that we solve, undestand and ultimately manipulate the mechanism of high temperature superconductivity and my research will aims to contribute towards that effort.
