    Gauge Invariance in Hamiltonian

    Homework Statement Hello Everyone I'm wondering, why in below product rule was not used for gradient of A where exponential is treated as constant for divergent of A and only for first term of equation we used the product rule? Homework Equations https://ibb.co/gHOauJ The Attempt at a Solution

    Graduate What is Mott Transition and its basic Priniciple?

    I found this paragraph from one of wiki article, "Mott considers a lattice model with just one electron per site. Without taking the interaction into account, each site could be occupied by two electrons, one with spin up and one with spin down. Due to the interaction the electrons would then...

    Thank you for your answer. I have knowledge of Band Energy formation and how insulator or conductors are formed. But I'm stuck where the mott transiton come in between and How electron interaction affect metals such that it becomes insulators.

    Graduate What is Mott Transition and its basic Priniciple?

    Hello Everyone, I was really curious to know what really is Mott Transition and How it works. I searched for hours but couldn't find any helpful answer. Somewhere it was suggested that it is a bridge between Quantum and Classical Mechanics and it is due to electron interaction where electron...
