Abstract:

Strong correlation between electrons drive the evolvement of quantum material from ordered to disordered phase. During this process, novel phenomena including superconductivity might occur. Our research is focused on the unconventional superconductivity in strongly correlated material. We investigated related problems, for example, the coexistence and competition between different phases; pairing symmetry and mechanism, in several strongly correlated materials by magnetic torque and transport measurements. Our experimental results suggest that unconventional superconductivity shares several common features, such as superconducting fluctuation of non-thermal origin, universal scaling behaviors which show close relationship between AFM, SC and QCP.  Our work sheds light to the understanding of the nature of unconventional superconductivity in strongly correlated material.
