MY THESIS: HEAVY FERMION

Heavy fermion materials are those intermetallic compounds which contain partially filled 4-f or 5-f orbital elements with an enormous effective mass of conducting electrons. These materials are very rich in terms of the study of the interaction between magnetic and electronic quantum fluctuation. The goal of recent interest in the heavy-fermion material is to couple electronic and magnetic properties to develop new classes of material behavior, for instance, high-temperature superconductivity, colossal magnetoresistance material, spintronics, and newly developed multi-ferroelectric material. There exists a “quantum critical point” (QCP) which represents a kind of singularity in the material phase diagram that modifies the metallic properties and gives the material some ideal states of matter including superconductivity. 

WHY ARE THEY IMPORTANT?

This is very important to question to address. as far as the physics of these kinds of materials we don't have much information, However, they contain various exotic quantum mechanical phenomenon, for instance, superconductivity can exist in a magnetic ordering state simultaneously. this type of superconductivity is not explained by BCS theory and considered unconventional. 

Global phase diagram can be seen below

Now, by modifying some non-thermal parameters (magnetic field, pressure, etc.)  can we make a material superconductor at room temperature?

This is some interesting question we will address during this project.
also, we will investigate the quantum criticality and what makes it happen in these kinds of material.

P.S. I will update you as I follow the project further
