The discovery of high-temperature superconductivity in cuprates ranks among the major scientific milestones of the past half century, yet pivotal questions regarding the complex phase diagram of these materials remain unanswered. Generally thought of as doped charge-transfer insulators, these complex oxides exhibit pseudogap, strange-metal, superconducting, and Fermi liquid behavior with increasing hole-dopant concentration. Motivated by recent experimental observations, here we introduce a phenomenological model wherein exactly one hole per planar copper-oxygen unit is delocalized with increasing doping and temperature. The model is percolative in nature, with parameters that are highly consistent with experiments. It comprehensively captures key unconventional experimental results, including the temperature and the doping dependence of the pseudogap phenomenon, the strange-metal linear temperature dependence of the planar resistivity, and the doping dependence of the superfluid density. The success and simplicity of the model greatly demystify the cuprate phase diagram and point to a local superconducting pairing mechanism.

Theoretical understanding of the vortex states of type II superconductors is reviewed, with a focus on thermodynamic phases and phase transitions. Results derived from computer simulations by our group are summarized. A new phase diagram for inter-layer Josephson vortices in layered superconductors is proposed.

In view of increasing emphasis on the use of next-nearest hopping t' term in the t - J Hamiltonian, we examine its effect on the spin susceptibility and its correlation with the structure of phase diagram. We find from this study that the resonance peak of spin susceptibility rapidly decreases with hole concentration in the overdoped region at which the spin singlet pairing order diminishes. It is shown that the doping dependence of resonance energy in both underdoped and overdoped regions is in agreement with observations.
