Abstract

In this talk we will discuss the experimental observations on the 
metal-insulator transition (MIT) in the 2D electron gas (2DEG)  and the 
thermodynamic measurements of the magnetic susceptibility and inverse 
compressibility of this system.   Next, our model based on density 
functional theory will be introduced, in which disorder and 
interactions are treated on the same footing without any assumption on 
their relative strength.   Obtained results on thermodynamic quantities 
and their relationship with the MIT will be discussed based on our 
ensemble averaged DFT-based calculations on this system.
