    • Structure factor of a relaxor ferroelectric 

      Guzmán Verri, Gian Giacomo; Varma, Chandra M. (2015-04-14)
      We study a minimal model for a relaxor ferroelectric including dipolar interactions, and short-range harmonic and anharmonic forces for the critical modes as in the theory of pure ferroelectrics together with quenched ...
    • Why is the electrocaloric effect so small in ferroelectrics? 

      Guzmán Verri, Gian Giacomo; Littlewood, Peter B. (2016-05-19)
      Ferroelectrics are attractive candidate materials for environmentally friendly solid state refrigeration free of greenhouse gases. Their thermal response upon variations of external electric fields is largest in the vicinity ...
