Abstract:The so-called Fröhlich entropy is the entropy variation of a material under the application of an electric field. This quantity can be calculated, under suitable hypotheses, directly from the measured real part of the dielectric function. Although Fröhlich entropy is defined for a biased sample, a straightforward physical interpretation correlates it to the state of order of the considered physical system in absence of field. When Fröhlich entropy is calculated from experimental results, its trend is able to g… Show more
