摘要
Studying the complexity of the electronic phase diagram is at the heart of understanding strongly correlated system in general,with high Tc superconductors as the most known examples.High temperature superconductivity has a wide range of application potentials in power transmission,nuclear magnetic resonance,magnetic levitation transportation,aerospace,information and communication technologies,etc.Understanding its mechanism remains a long-standing challenge,due to its complex material structures and interlays among different phases such as charge density wave,antiferromagnetic and superconducting phases.As a result,this has greatly hindered its further development.
