Abstract
Using the non-crossing approximation, we present the finite temperature superconducting phase diagram in the multi-orbital heavy fermion superconducting system. Besides the phase transition from the superconducting state to the normal state with the increase of temperature, we find a reentrant behavior of superconducting state due to competition between the superconductivity and the Kondo effect. There are two independent parameters to control the superconducting properties in this multi-orbital heavy fermion superconducting system. At the same time, the orbital degree of freedom also has important influence on the superconducting phase diagram.
Coffee and tea will be served 20 minutes prior to the seminar.
