We find that the diamagnetic and Nernst signals decay strongly with temperature in a manner which is dictated by the vortex core energy. Furthermore, we find that the ratio between the magnetization and the transverse thermoelectric conductivity tends to a constant. We use the theory to interpret measurements of underdoped La2-xSrxCuO4\u00a0above the critical temperature regime and obtain a considerably better fit to the data than a fit based on Gaussian order-parameter fluctuations. Our results indicate that the core energy in this system scales roughly with the critical temperature.
