Description

We build a continuous fluctuating description of elastic, conductive and dissipative solids
subject to heat fluxes, which takes fully into account linear thermoelastic couplings.
Under the assumption of local equilibrium, we derive an extension of the fluctuation-dissipation theorem
and obtain the strain fluctuations in the nonequilibrium steady state.
We outline next steps towards the assessment of thermal noise for Advanced VIRGO,
Advanced LIGO and next generation of gravitational wave interferometers in realistic nonequilibrium conditions.
