Title: Three-nucleon Interactions: A Frontier in Nuclear Structure Speaker: Achim Schwenk, TRIUMF Abstract: Three-nucleon interactions are a frontier in understanding and predicting the structure of strongly-interacting matter in laboratory nuclei and in the cosmos. I will present results and discuss the status of first calculations with microscopic three-nucleon interactions beyond light nuclei. This coherent effort is possible due to advances based on effective field theory and renormalization group methods in nuclear physics.
