- Abstract
The coexistence and interplay between spin, charge, orbital and lattice in electron correlated systems give rise to many interesting quantum phenomena, including unconventional superconductivity, colossal magnetoresistance, metal-insulator transition, topological phase transition, etc. While, as one of the most important issues in condensed matter physics, the mechanism of the unconventional high temperature superconductivity is still unclear up to now. In this paper, we report some new phenomena/physics obtained from our high pressure studies on three typically unconventional superconductors--heavy fermion superconductor, cuprate high temperature superconductor and iron-based superconductor, which include the correlation between magnetism and superconductivity, the influence of valence change on superconductivity, the discovery of superconductivity reemerging, the bi-critical points, and the universal transition from superconducting to insulating-like states, etc. These high-pressure experimental results on the unconventional superconductors are expected to provide useful information for a better understanding on the unconventional superconducting mechanism.
