Description of resonances in light nuclei using a microscopic cluster model
Theodoros Leontiou, Niels R. Walet
We investigate resonances in light halo nuclei using a fully microscopic cluster model and the complex scaling method. We make use of the hermitian representation of the complex sc…
Baryon structure in a quark-confining non-local NJL model
Amir H. Rezaeian, Niels R. Walet, Michael C. Birse
We study the nucleon and diquarks in a non-local Nambu-Jona-Lasinio model. For certain parameters the model exhibits quark confinement, in the form of a propagator without real pol…
Exact renormalization group and many-fermion systems
B. Krippa, M. C. Birse, J. A. McGovern +1
The exact renormalization group methods is applied to many fermion systems with short-range attractive force. The strength of the attractive fermion-fermion interaction is determin…
Pairing in Many-Fermion Systems: An Exact Renormalisation Group Treatment
Michael C. Birse, Boris Krippa, Judith A. McGovern +1
We study the application of the exact renormalisation group to a many-fermion system with a short-range attractive force. We introduce a boson field to describe pairing effects, an…
Variational Monte Carlo for Microscopic Cluster Models
Theodoros Leontiou, Niels R. Walet
We examine the application of the Variational Monte Carlo (VMC) method to a cluster model for halo nuclei. Particular attention is paid to the error estimate in the presence of cor…
Oblate-prolate shape coexistence at finite angular momentum
Daniel Almehed, Niels R. Walet
We investigate shape coexistence in a rotating nucleus. We concentrate on the interesting case of 72-Kr which exhibits an interesting interplay between prolate and oblate states as…
