In the present work we study the polar properties of domain walls using a recently developed method of combining layer group analysis with order parameter symmetry [Schranz et al. PRB 100 (2019) 184105]. Using this method we obtain a detailed overview on the microscopic and macroscopic properties of domain walls which we can quantify with results from Landau-Ginzburg-Devonshire theory. Recently, we have applied [Schranz et al. PRB 102 (2020) 184101] the method to analyse the symmetry and polar properties of ferroelastic twin walls and antiphase boundaries in SrTiO3. Here we discuss the elastic anomalies observed in SrTiO3 at various temperatures in the light of these findings.
