Nearsightedness of Electronic Matter
E. Prodan, W. Kohn
In an earlier paper, W. Kohn had qualitatively introduced the concept of "nearsightedness" of electrons in many-atom systems. It can be viewed as underlying such important ideas as…
Symmetry breaking in the self-consistent Kohn-Sham equations
E. Prodan
The Kohn-Sham (KS) equations determine, in a self-consistent way, the particle density of an interacting fermion system at thermal equilibrium. We consider a situation when the KS…
The phase diagram for the model
E. Prodan
The two parameter model is reduced to a one parameter model by using simple transformations. Because the separation between different phase regions for a one parameter model is jus…
Gaussian, Mean Field and Variational Approximation: the Equivalence
E. Prodan
We show the equivalence between the three approximation schemes for self-interacting (1+1)-D scalar field theories. Based on rigorous results of [1, 2], we are able to prove that t…
Transport properties of fermionic systems
E. Prodan
We extend the method discovered by A Y Alekseev et al to the case of fermions in external fields. A general formula for conductance G is proved. In the (1+1)-D case with symmetry a…
