Breaking Bipartite and Time Reversal Symmetries by Fusing Porphine Unit in-between two Zigzag-edge Graphene Nanoribbons
R. K. Rohit, Jisvin Sam, Sudipta Dutta
Hybrid structure of two zigzag-edge graphene nanoribbons with a fused porphine ring in between, results in two distinct nearly degenerate ground states: a semiconducting antiferrom…

Quantum Interference Driven Electron Transport through Fano-Anderson Systems
Koushik R. Das, Sudipta Dutta
We investigate the electronic transport behavior of Fano-Anderson (FA) systems, consisting of a one-dimensional finite backbone chain and an attached side-group of varying length.…

Quantum Transport through Asymmetrical Molecular channel Azulene: Role of Orbital Interference
Koushik R. Das, Sudipta Dutta
We investigate electron transport through azulene molecule with four distinct electrode contact geometries using the non-equilibrium Green's function formalism within the tight-bin…
