Abstract
We study the emergence of triplet superconductivity in an electronic system near a ferromagnetic quantum critical point (FQCP). Previous studies found that the superconducting transition is of second order, and Tc is strongly reduced near the FQCP due to pair-breaking effects from thermal spin fluctuations. In contrast, we show that near the FQCP, the system avoids pair-breaking by undergoing a first order transition at a much larger Tc. At some distance from the FQCP, a second order superconducting transition emerges at a tricritical point.
