Propagation of thermally induced magnonic spin currents [PDF]

Physical Review B, 2014
The propagation of magnons in temperature gradients is investigated within the framework of an atomistic spin model with the stochastic Landau-Lifshitz-Gilbert equation as underlying equation of motion. We analyze the magnon accumulation, the magnon temperature profile as well as the propagation length of the excited magnons. The frequency distribution

Laser phase noise to intensity noise conversion by lowest-order group-velocity dispersion in optical fiber: exact theory [PDF]

, 2000
An exact result for the spectral density of intensity variations that occur after propagation of ergodic light in a medium having lowest-order-only group-velocity dispersion is obtained and applied to the problem of semiconductor laser phase noise to ...

Analytic properties of thermal corrected boson propagators [PDF]

Physical Review D, 2003
We investigate the analytic properties of finite-temperature self-energies of bosons interacting with fermions at one-loop order. A simple boson-fermion model was chosen due to its interesting features of having two distinct couplings of bosons with fermions.

Propagating Thermal Modes in a Fluid under Thermal Constraint

Physical Review Letters, 1979
In a stably stratified fluid layer there is a transition beyond which an oscillatory behavior appears. Using forced-Rayleigh-scattering spectroscopy, we found experimental evidence for the existence of propagating modes in agreement with the theoretical predictions.

Experimental Investigation for the Phase Change Material Barrier Area Effect on the Thermal Runaway Propagation Prevention of Cell-to-Pack Batteries

Batteries, 2023
Thermal runaway propagation (TRP) is a primary safety issue in lithium-ion battery (LIB) applications, and the use of a thermal barrier is considered to be a promising solution for TRP prevention.

Thermal propagation of normal-superconductor boundaries [PDF]

Physica B+C, 1981
Abstract The model of Newhouse for thermal propagation of long normal regions in thin superconducting films on good thermal conducting substrates has been verified. Measurements show much slower velocities for short regions, but the dependence is compatible with a new model calculation.
