Generating Superposition of Transverse Ising Ground States by Quantum Interaction
Koushik Das, Sayan Mondal, Ujjwal Sen
We investigate superpositions of quantum Ising ground states generated through a quantum interaction, in which the nearest-neighbor coupling strength is promoted to an operator act…
Odd diffusion and power-law correlations in chiral mass-transport processes
Koushik Das, Animesh Hazra, Punyabrata Pradhan
We study mass-conserving Markov jump processes on a square lattice, where masses hop with a preferred rotational sense, thus breaking both time-reversal and mirror symmetries. We c…
Hierarchy of topological superconductivity generated via heterostructures of unconventional -wave magnets
Koushik R. Das, Arijit Saha
A theoretical framework is proposed to engineer both first and second-order topological superconducting phases in a two-dimensional (2D) heterostructure, consisting of a quantum sp…
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…
Asymmetric Electronic Transport in Porphine: Role of Atomically Precise Tip-Electrode
Koushik R. Das, Sudipta Dutta
Electronic conductance through a single molecule is sensitive towards its structural orientation between two electrodes, owing to the distribution of molecular orbitals and their c…
