A General Algorithm For Determining The Conductivity Zeros In Large Molecular Nanostructures: Applications To Rectangular Graphene Sheets

Marian Nita, Mugurel Tolea, Catalina Marinescu

We propose an algorithm for determining the zeros of the electric conductivity in large molecular nanonstructures such as graphene sheets. To this end, we employ the inverse graph…

Conductance zeros in complex molecules and lattices from the interference set method

M. Nita, M. Tolea, D. C. Marinescu

Destructive quantum interference (DQI) and its effects on electron transport is studied in chemical molecules and finite physical lattices that can be described by a discrete Hamil…

Robust conductance zeroes in graphene quantum dots and other bipartite systems

M. Nita, M. Tolea, D. C. Marinescu

Within the Landauer transport formalism we demonstrate that conductance zeroes are possible in bipartite systems at half-filling when leads are contacted to different sublattice si…

Edge states mechanism for the anomalous quantum Hall effect in diatomic square lattice

B. Ostahie, M. Nita, A. Aldea

The understanding of the Chern insulator and anomalous quantum Hall effect (AQHE) in terms of chiral edge states in confined systems is the first aim of the paper. The model we use…

Hund and anti-Hund rules in circular molecules

M. Nita, M. Tolea, D. C. Marinescu +1

We study the validity of Hund's first rule for the spin multiplicity in circular molecules - made of real or artificial atoms such as quantum dots - by considering a perturbative a…

Non-Hermitian approach of edge states and quantum transport in a magnetic field

B. Ostahie, M. Nita, A. Aldea

We develop a manifest non-Hermitian approach of spectral and transport properties of two- dimensional mesoscopic systems in strong magnetic field. The finite system to which severa…
