Effective shell model Hamiltonians from density functional theory: quadrupolar and pairing correlations
R. Rodriguez-Guzman, Y. Alhassid, G. F. Bertsch
We describe a procedure for mapping a self-consistent mean-field theory (also known as density functional theory) into a shell model Hamiltonian that includes quadrupole-quadrupole…
A new effective interaction for the trapped Fermi gas
Y. Alhassid, G. F. Bertsch, L. Fang
We apply the configuration-interaction method to calculate the spectra of two-component Fermi systems in a harmonic trap, studying the convergence of the method at the unitary inte…
Dipole Oscillations in Bose - Fermi Mixture in the Time-Dependent Grosspitaevskii and Vlasov equations
Tomoyuki Maruyama, George F. Bertsch
We study the dipole collective oscillations in the bose-fermi mixture using a dynamical time-dependent approach, which are formulated with the time-dependent Gross-Pitaevskii equat…
Unitary Fermi Gas in a Harmonic Trap
S. Y. Chang, G. F. Bertsch
We present an {\it ab initio} calculation of small numbers of trapped, strongly interacting fermions using the Green's Function Monte Carlo method (GFMC). The ground state energy,…
Neutron-Proton pairing revisited
W. A. Friedman, G. F. Bertsch
We reexamine neutron-proton pairing as a phenomenon that should be explanable in a microscopic theory of nuclear binding energies. Empirically, there is an increased separation ene…
Moment distributiuons of clusters and molecules in the adiabatic rotor model
G. E. Ballentine, G. F. Bertsch, N. Onishi +1
We present a Fortran program to compute the distribution of dipole moments of free particles for use in analyzing molecular beams experiments that measure moments by deflection in…
