Anomalous Specific Heat in Ultradegenerate Qed and Qcd

We discuss the origin of the anomalous T lnT behavior of the low-temperature entropy and specific heat in ultradegenerate QED and QCD and report on a recent calculation which is complete to leading order in the coupling and which contains an infinite series of anomalous terms involving also fractional powers in T . This result involves dynamical hard-dense-loop resummation and interpolates betw...

SCHOTTKY-LIKE ANOMALY IN THE LOW-TEMPERATURE SPECIFIC HEAT OF POLYCRYSTALLINE Y0.3Gd0.2Sr0.5MnO3

In this paper we have synthesis of a sample of Y0.3Gd0.2Sr0.5MnO3 by solid state ceramic route method. The structural and thermodynamic properties of polycrystalline samples of Y0.3Gd0.2Sr0.5MnO3 were measured in order to investigate the effect of higher magnetic moment ion Gd and divalent Sr over Y ion. The structural transition from hexagonal to orthorhombic is observed at very high doping of...

Anomalous heat diffusion.

Consider anomalous energy spread in solid phases, i.e., <Δx(2)(t)>E≡∫(x-E)(2)ρE(x,t)dx∝t(β), as induced by a small initial excess energy perturbation distribution ρE(x,t=0) away from equilibrium. The second derivative of this variance of the nonequilibrium excess energy distribution is shown to rigorously obey the intriguing relation d(2)<Δx(2)(t)>E/dt2=2CJJ(t)/(kBT(2)c), where CJJ(t) equals...

Simulation of Heat Treatment Distortion

This paper gives an overview of the problem of heat treatment stress and distortion and a review of literature surrounding it. Software developed to predict heat treat distortion is also reviewed. Simulations are presented for a quenched cylinder to demonstrate the capabilities of software available for predicting heat treatment stress and distortion. The software package DANTE was identified a...

Weak ferromagnetic exchange and anomalous specific heat in ZnCu3(OH)6Cl2.

Experimental evidence for a plethora of low energy spin excitations in the spin-1/2 kagome antiferromagnet ZnCu3(OH)6Cl2 may be understandable in terms of an extended Fermi surface of spinons coupled to a U(1) gauge field. We carry out variational calculations to examine the possibility that such a state may be energetically viable. A Gutzwiller-projected wave function reproduces the dimerizati...
