Role of pinning potentials in heat transport through disordered harmonic chain
Dibyendu Roy, Abhishek Dhar
The role of quadratic onsite pinning potentials on determining the size (N) dependence of the disorder averaged steady state heat current <J>, in a isotopically disordered harmonic…
Langevin dynamics in crossed magnetic and electric fields: Hall and diamagnetic fluctuations
Dibyendu Roy, N. Kumar
Based on the classical Langevin equation, we have re-visited the problem of orbital motion of a charged particle in two dimensions for a normal magnetic field crossed with or witho…
Crossover from ballistic to diffusive thermal transport in quantum Langevin dynamics study of a harmonic chain connected to self-consistent reservoirs
Dibyendu Roy
Through an exact analysis using quantum Langevin dynamics, we demonstrate the crossover from ballistic to diffusive thermal transport in a harmonic chain with each site connected t…
Scattering of electrons from an interacting region
Abhishek Dhar, Diptiman Sen, Dibyendu Roy
We address the problem of transmission of electrons between two noninteracting leads through a region where they interact (quantum dot). We use a model of spinless electrons hoppin…
