Properties of nuclei in the neutron star crust
Piotr Magierski, Aurel Bulgac, Paul-Henri Heenen
In the present study we investigate the static properties of nuclei in the inner crust of neutron stars. Using the Hartree-Fock method in coordinate space, together with the semicl…
Selected aspects of physics of fermionic bubbles
Piotr Magierski, Aurel Bulgac
We discuss properties of the Fermi system which contain one or more spherical (or almost spherical) objects. The interplay between various effects, such as shell correction and cha…
Local Density Approximation for Pairing Correlations in Nuclei
Aurel Bulgac, Yongle Yu
We introduce a natural and simple to implement renormalization scheme of the Hartree-Fock-Bogoliubov (HFB) equations for the case of zero range pairing interaction. This renormaliz…
Local Density Approximation for Systems with Pairing Correlations
Aurel Bulgac
I formulate a local density approximation for fermion systems with pairing correlations based on a rapidly converging renormalization scheme for the pairing gap.
Renormalization of the Hartree-Fock-Bogoliubov Equations in the Case of a Zero Range Pairing Interaction
Aurel Bulgac, Yongle Yu
We introduce a natural and simple to implement renormalization scheme of the Hartree-Fock-Bogoliubov (HFB) equations for the case of zero range pairing interaction. This renormaliz…
Casimir Interaction among Objects Immersed in a Fermionic Environment
Aurel Bulgac, Andreas Wirzba
Using ensembles of two, three and four spheres immersed in a fermionic background we evaluate the (integrated) density of states and the Casimir energy. We thus infer that for suff…
