Comparison of the optically measured vaporization energy by ultrafast laser spectroscopy and condensation energy determined from specific heat measurements in superconducting cuprates

Condensation energy can be thought as the difference in ground state energy between the normal state and the superconducting state in a superconductor. In a way to understand and prove theory for superconducting transition, an accurate measurement of the condensation energy is needed [1]. The most common method for determination of condensation energy is by measuring the thermodynamical critical field and alternatively, condensation energy can be found by integrating the difference in specific heats in the normal and superconducting states from 0 = T to the superconducting transition temperature c T
