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…
Influence of spin fluctuations near the Mott transition: a DMFT study
Serge Florens, Priyanka Mohan, C. Janani +2
Dynamics of magnetic moments near the Mott metal-insulator transition is investigated by a combined slave-rotor and Dynamical Mean-Field Theory solution of the Hubbard model with a…
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…
Long Range Coulomb Interactions and Nanoscale Electronic Inhomogeneities in Correlated Oxides
Vijay B. Shenoy, Tribikram Gupta, H. R. Krishnamurthy +1
Electronic, magnetic or structural inhomogeneities ranging in size from nanoscopic to mesoscopic scales seem endemic, and are possibly generic, to colossal magnetoresistance mangan…
Dimensional and temperature dependence of metal insulator transition in correlated and disordered systems
Tribikram Gupta, Sanjay Gupta
We study the dimensional dependence of the interplay between correlation and disorder in two dimension at half filling using 2D disordered Hubbard model with deterministic d…
