Diagrammatic Monte Carlo for Finite Systems at Zero Temperature

Author(s): Stefano Brolli, Carlo Barbieri, and Enrico Vigezzi High-order virtual excitations play an important role in microscopic models of nuclear reactions at intermediate energies. However, the factorial growth of their complexity has prevented their consistent inclusion in ab initio many-body calculations. For infinite systems at finite temperature, such … [Phys. Rev.
