Thermally Activated Processes in Polymer Glasses
V. Parihar, D. Drosdoff, A. Widom +1
A derivation is given for the Vogel-Fulcher-Tammann thermal activation law for the glassy state of a bulk polymer. Our microscopic considerations involve the entropy of closed poly…
The Clausius-Mossotti Phase Transition in Polar Liquids
S. Sivasubramanian, A. Widom, Y. N. Srivastava
The conventional Clausius-Mossotti polarization equation of state is known to be unstable for polar liquids having molecules with high polarizability. Room temperature water is an…
Thermodynamic QED Coherence in Condensed Matter: Microscopic Basis of Thermal Superradiance
S. Sivasubramanian, A. Widom, Y. N. Srivastava
Electromagnetic superradiant field coherence exists in a condensed matter system if the electromagnetic field oscillators undergo a mean displacement. Transitions into thermal stat…
Thermal Superradiance and the Clausius-Mossotti Lorentz-Lorenz Equations
S. Sivasubramanian, A. Widom, Y. N. Srivastava
Electric polarization phenomena in insulating systems have long been described in mean field theory by the (static) Clausius-Mossotti or (dynamic) Lorentz-Lorenz polarizabilities.…
Radiation Induced Landau-Lifshitz-Gilbert Damping in Ferromagnets
S. Sivasubramanian, A. Widom, Y. N. Srivastava
The Landau-Lifshitz-Gilbert damping coefficient employed in the analysis of spin wave ferromagnetic resonance is related to the electrical conductivity of the sample. The changing…
Physical Kinetics of Ferroelectric Hysteresis
S. Sivasubramanian, A. Widom
The physical kinetics of single domain ferroelectric materials are studied using Landau-Khalatnikov equation. The hysteretic curves are obtained numerically. The effective coercive…
