An Exactly Solvable Model of Interacting Bosons
We introduce a class of exactly solvable boson models. We give explicit analytic expressions for energy eigenvalues and eigenvectors for an sd-boson Hamiltonian, which is related to the SO(6) chain of the Interacting Boson Model Hamiltonian.
متن کاملShell Model Description of 158 Gd
The pseudo-SU(3) model is used to describe the low-energy spectra as well as E2 and M 1 transition strengths in 158 Gd. The Hamiltonian includes spherical single-particle energies, the quadrupole-quadrupole and proton and neutron pairing interactions, plus four rotor-like terms. The parameters of the Hamiltonian were fixed by systematics with the rotor-like terms determined through a least-squa...
متن کاملShell-Model Description of Λ Hypernuclei
Empirical data on the spectra of light hypernuclei, especially the data from recent γ-ray experiments, is used to constrain the parameters which govern the p N s Λ and p N p Λ two-body matrix elements that enter into shell-model calculations.
متن کاملYrast line for weakly interacting trapped bosons
We compute numerically the yrast line for harmonically trapped boson systems with a weak repulsive contact interaction, studying the transition to a vortex state as the angular momentum L increases and approaches N , the number of bosons. The L = N eigenstate is indeed dominated by particles with unit angular momentum, but the state has other significant components beyond the pure vortex config...
متن کاملStrongly interacting W bosons and supersymmetry.
We present arguments in favor of the idea that supersymmetric sigma models with compact symmetric Kähler spaces as target manifolds have a second-order phase transition in four dimensions. When applied to electroweak symmetry breaking, these models then do not require a light Higgs boson or techni-resonances but predict fermionic superpartners of longitudinal W's and Z with masses at or below T...
