Ab initio theory of nuclear matter from low to high densitiesHYBRID

Infinite nuclear matter bridges the vastly different scales of finite nuclei and neutron stars. Since it is not directly observable, unbiased theoretical predictions are crucial for its understanding. 
In this seminar, I will present a comprehensive ab initio picture of nuclear matter at zero temperature. Using Gorkov Green's function theory [1], I will discuss the equations of state from chiral interactions [2] and the emergence of superfluidity in low-density neutron matter [3].
