Numerical package for QFT calculations of defect-induced phenomena in graphene
Hillol Biswas, Harshitra Mahalingam, Aleksandr Rodin
We introduce a computationally efficient method based on the path integral formalism to describe defect-modified graphene. By taking into account the entire Brillouin zone, our app…
Gate-tunable artificial nucleus in graphene
Mykola Telychko, Keian Noori, Hillol Biswas +12
We report an atomically-precise integration of individual nitrogen (N) dopant as an in-plane artificial nucleus in a graphene device by atomic implantation to probe its gate-tunabl…
Graphene-mediated interaction between adsorbed impurities
Keian Noori, Hillol Biswas, Su Ying Quek +1
Interaction between adsorbed atoms in graphene is studied using a combination of DFT and the path integral formalism. Our results reveal a complex non-monotonic interaction profile…
Elimination of thermal bistability in superconducting weak links by an inductive shunt
Sourav Biswas, Clemens B. Winkelmann, Hervé Courtois +3
The quantum phase-coherent behavior of superconducting weak links (WL) is often quenched in the finite voltage state, due to the heat dissipation and related thermal hysteresis. Th…
