HI! My problem is next: I have 2-d electron gas with included interaction between electrons of opposite spins V_{\sigma}=N_{\sigma}U where U > 0 and \sigma=\pm1 is spin up or down, and pauli interaction with outside field B is included. I have to calculate the total energy of gas at T=0K as...

HI! Also: I have 1-d electron gas in tight banding model with included interaction between electrons of same spins V_{\uparrow}=-N_{\uparrow}U where U > 0, \sigma=\pm1 is spin up or down, and pauli interaction with outside field B is included. I have to calculate the total energy of gas at...
