Electronic transport in single-helical protein molecules: Effects of multiple charge conduction pathways and helical symmetry
Sourav Kundu, S. N. Karmakar
We propose a tight-binding model to investigate electronic transport properties of single helical protein molecules incorporating both the helical symmetry and the possibility of m…
Multiple mobility edges in a 1D Aubry chain with Hubbard interaction in presence of electric field: Controlled electron transport
Srilekha Saha, Santanu K. Maiti, S. N. Karmakar
Electronic behavior of a 1D Aubry chain with Hubbard interaction is critically analyzed in presence of electric field. Multiple energy bands are generated as a result of Hubbard co…
Circulating persistent current and induced magnetic field in a fractal network
Srilekha Saha, Santanu K. Maiti, S. N. Karmakar
We present the overall conductance as well as the circulating currents in individual loops of a Sierpinski gasket (SPG) as we apply bias voltage via the side attached electrodes. S…
Detection of basepair mismatches in DNA using graphene based nanopore device
Sourav Kundu, S. N. Karmakar
We present an unique way to detect basepair mismatches in DNA leading to different epigenetic disorder by the method of nanopore sequencing. Based on a tight-binding formulation of…
Conformation dependent magnetotransport in a single handed helical geometry
Srilekha Saha, Santanu K. Maiti, S. N. Karmakar
Conformation dependent circular current is investigated in a single handed helical geometry in presence of magnetic flux within a Hartree-Fock mean field approach. The helical…
Graphene nanopore devices for DNA sequencing: A tight-binding model study
Sourav Kundu, S. N. Karmakar
We present a tight-binding model study of a two-terminal graphene nanopore device for sequential determination of DNA bases. Using Green's function technique we investigate the cha…
