Complex quasiparticle energy

Research output: Chapter in Book/Report/Conference proceedingConference contribution


We show how calculate the energies and the widths of quasiparticle resonant states without solving the complex bcs equations. The method is based on BCS equations solved in the real representation including the continuum. In this representation the quasiparticle resonances are associated to the Gamow states of the mean field.
