N2 - Electronic states around vortex cores in high-Tc cuprates are studied using the t-J model based on the conventional Gutzwiller approximation and Bogoliubov-de Gennes (BdG) theory. When the system is near the optimum doping, local density of states at the center of the core does not have the zero-energy peak (ZEP). We have clarified that the absence of ZEP is attributed to the existence of the staggered flux state inside the core which is a peculiar feature to small size of vortex core.
