Heat transport in ordered harmonic lattices
Dibyendu Roy, Abhishek Dhar
We consider heat conduction across an ordered oscillator chain with harmonic interparticle interactions and also onsite harmonic potentials. The onsite spring constant is the same…
Decohering d-dimensional quantum resistance
Dibyendu Roy, N. Kumar
The Landauer scattering approach to 4-probe resistance is revisited for the case of a d-dimensional disordered resistor in the presence of decoherence. Our treatment is based on an…
Electron transport in an open mesoscopic metallic ring
Dibyendu Roy
We study electron transport in a normal-metal ring modeled by the tight binding lattice Hamiltonian, coupled to two electron reservoirs. First, Buttiker's model of incorporating in…
Random-phase reservoir and a quantum resistor: The Lloyd model
Dibyendu Roy, N. Kumar
We introduce phase disorder in a 1D quantum resistor through the formal device of `fake channels' distributed uniformly over its length such that the out-coupled wave amplitude is…
