Physics of interface: Barrier with correlations and disorder sandwiched between two metallic planes
Sanjay Gupta, Tribikram Gupta
A Metal-Disordered Mott insulator-Metal heterostructure is studied at half-fiiling using unrestricted Hartree Fock method. The corresponding clean system has been shown to be an in…

Physics of interface: Strongly correlated barrier with chemical modulation sandwiched between two metallic planes
Tribikram Gupta, Sanjay Gupta
Barrier planes described by the Ionic Hubbard model and sandwiched between metallic planes on both sides are studied using unrestricted Hartree Fock. For zero onsite correlation, t…

Physics of interface: Mott insulator barrier sandwiched between two metallic planes
Sanjay Gupta, Tribikram Gupta
We consider a heterostructure of a metal and a barrier with onsite correlation at half filling using unrestricted Hartree Fock. We find that above a certain value of correlation st…
