nanocalorimeter spectroscopy of strongly correlated metals

Heat capacity measurements provide essential information about the full extent of low energy excitation in the strongly correlated systems. Nuclear schottky often obscure the physics in these systems. I will discuss a new calorimeter spectroscopy technique that -- coupled with ultrafast nanocalorimeters -- allows determination of electronic and nuclear components of heat capacity using time as a new experimental parameter. These measurements yield spin lattice relaxation time which provides information complementary to NMR. Calorimeter spectroscopy enables two independent determinations of electronic density of states in a strongly correlated system in a single measurement.
