Dielectric determination of the glass transition temperature (T sub g) [PDF]

open access: yes
The objective is to determine the glass transition temperature of a polymer using a dielectric dissipation technique. A peak in the dissipation factor versus temperature curve is expected near the glass transition temperature T sub g.

Segregation by thermal diffusion of an intruder in a moderately dense granular fluid

open access: yes, 2009
A solution of the inelastic Enskog equation that goes beyond the weak dissipation limit and applies for moderate densities is used to determine the thermal diffusion factor of an intruder immersed in a dense granular gas under gravity.

The Dissipative Spectral Form Factor for I.I.D. Matrices

open access: yesJournal of Statistical Physics
The Dissipative Spectral Form Factor (DSFF), recently introduced in [arXiv:2103.05001] for the Ginibre ensemble, is a key tool to study universal properties of dissipative quantum systems. In this work we compute the DSFF for a large class of random matrices with real or complex entries up to an intermediate time scale, confirming the predictions from [

Exploring High Voltage Potential of 3D Printed Capacitors: A Filament-Based Comparison Through Dielectric Performance Analysis

open access: yesApplied Sciences
Recent advancements in 3D printing technology have enabled the rapid production of complex structures, yet the dielectric performance of 3D printing materials and their potential for manufacturing electrical components remain insufficiently studied.

Thermodynamics of an Accretion Disk Annulus with Comparable Radiation and Gas Pressure

open access: yes, 2007
We explore the thermodynamic and global structural properties of a local patch of an accretion disk whose parameters were chosen so that radiation pressure and gas pressure would be comparable in magnitude.

Dielectric frequency response measurements and dissipation factor temperature dependence

open access: yes2012 IEEE International Symposium on Electrical Insulation, 2012
The condition of the insulation is an essential aspect for the operational reliability of electrical power transformers, generators, cables and other high voltage equipment. Transformers with high moisture content can not without risk sustain higher loads.

Fluctuation corrections on thermodynamic functions: Finite size effect

open access: yes, 2013
The explicit thermodynamic functions, in particular, the specific heat of a spin system interacting with a spin bath which exerts finite dissipation on the system are determined.

Thermoelastic dissipation in inhomogeneous media: loss measurements and displacement noise in coated test masses for interferometric gravitational wave detectors

open access: yes, 2004
The displacement noise in the test mass mirrors of interferometric gravitational wave detectors is proportional to their elastic dissipation at the observation frequencies. In this paper, we analyze one fundamental source of dissipation in thin coatings,

Quantum Friction in Nanomechanical Oscillators at Millikelvin Temperatures

open access: yes, 2006
We report low-temperature measurements of dissipation in megahertz-range, suspended, single-crystal nanomechanical oscillators. At millikelvin temperatures, both dissipation (inverse quality factor) and shift in the resonance frequency display ...
