Abstract:
Many-Body Nuclear Problem remains one of the main challenges within theoretical physics. We simultaneously face the problems to describe interactions among baryons and to solve the quantum many-body dynamics.
In this talk we discuss in detail an Equation of Motion Phonon Method (EMPM). This method constructs and solves iteratively a set of equations of motion to generate a multiphonon basis built of particle-hole or quasiparticle Tamm Dancoff phonons. The basis so obtained is then used to solve the eigenvalue problem in the full multiphonon space.
We discuss recent applications of EMPM on neutron rich even-even nuclei, odd-even nuclei with a valence particle or hole, and single Lambda hypernuclei. Additionaly, attention will be paid on few recent technical advances – the application of the single-particle basis of Natural Orbitals and the Singular Value Decomposition (SVD) method used for the separation of the Centre of Mass spuriosity.
