Quantum Communication
Nicolas Gisin
Quantum Communication is the art of transferring an unknown quantum state from one location, Alice, to a distant one, Bob. This is a non-trivial task because of the quantum no-clon…
A generalized enhanced Fourier law and underlying connections to major frameworks for quasi-ballistic phonon transport
Ashok T. Ramu, John E. Bowers
An enhanced Fourier law (EFL) that accounts for quasi-ballistic phonon transport effects in a formulation entirely in terms of physical observables, is derived from the Boltzmann t…
On the solenoidal heat-flux in quasi-ballistic thermal conduction
Ashok T. Ramu, John E. Bowers
The Boltzmann transport equation for phonons is recast directly in terms of the heat-flux by means of iteration followed by truncation at the second order in the spherical harmonic…
A compact heat transfer model based on an enhanced Fourier law for analysis of frequency-domain thermoreflectance experiments
Ashok T. Ramu, John E. Bowers
A recently developed enhanced Fourier law is applied to the problem of extracting thermal properties of materials from frequency-domain thermoreflectance (FDTR) experiments. The he…
Quasi-ballistic phonon transport effects on the determination of the mean-free path accumulation function for the effective thermal conductivity
Ashok T. Ramu, John E. Bowers
The mean-free path (MFP) accumulation function for the effective thermal conductivity, introduced by Dames and Chen is a compact, universal and highly useful summary of the effect…
