Conditions

  • a polar molecular liquid is maintained under a spatial temperature gradient
  • the response is the non-equilibrium polarization / electrostatic field of the liquid itself, not ionic thermodiffusion and not the pyroelectric response of an already ordered ferroelectric fluid (Máthé et al. 2022's ferroelectric-nematic thermomotor is that other coupling)
  • simulation only: no experiment has measured the polarization of an ordinary polar liquid under a temperature gradient (pass 32 web search, not a route-search-v1 negative)

Constitutive relation

input Temperature gradientoutput Electric fieldliquid thermopolarization coefficient S_TP [V/K]

the field along the gradient; Gittus, Albella & Bresme 2020 give S_TP ≈ −0.6 mV/K for acetonitrile near standard conditions and Bresme et al. 2008 fields of order 10⁶ V/m for water at 10⁸ K/m, both from non-equilibrium molecular dynamics; the sign reverses with temperature in water (Armstrong & Bresme 2015)
