Abstract
Abstract Studies of the low-temperature heat capacity in the titanates La 1− x Sr x TiO 3 and Y 1− x Ca x TiO 3 have showed a significant increase of the coefficient of electronic specific heat, γ, due to the strong electronic correlations on approaching the metal-insulator transition boundary. The Mott transition is characterized by the divergent increase of renormalized electron mass with band filling.
