چکیده

The purpose of this paper is to introduce the unitary limit as applied in systems cold atoms into collective states heavy and even-even nuclei identify a related physical example. This accompanied by determination observables conformal symmetry nuclear structure. A Hamiltonian defined that governs scattering process an incident pair two slow neutrons onto heavy, target nucleus framework Interacting Boson Model pair-collective state interaction introduced along with effective range expansion for length. solutions coupled channels equations provide couples intermediate A+2n compound nucleus. manifests itself when correspond resonances positions which coincide energies IBM closed channels. position width each resonance measurable via fluctuation cross section tunes Conformal represented tower equally spaced emerges at from two-boson excitations on channel. These are regularity pattern fluctuations section, terms regular widths. manifestation indicates laboratory examination BCS-BEC crossover, underlying critical point algebras infinite number generators.

Extended Conformal Symmetry

We show that the grading of fields by conformal weight, when built into the initial group symmetry, provides a discrete, non-central conformal extension of any group containing dilatations. We find a faithful vector representation of the extended conformal group and show that it has a scale-invariant scalar product and satisfies a closed commutator algebra. The commutator algebra contains the i...

Utilizing Symmetry Coupling Schemes in Ab Initio Nuclear Structure Calculations

We report on ab initio no-core shell model calculations in a symmetryadapted SU(3)-based coupling scheme that demonstrate that collective modes in p-shell nuclei emerge from first principles. The low-lying states of Li, He, Be, B, C, and O, are shown to exhibit orderly patterns that favor spatial configurations with strong quadrupole deformation and complementary low intrinsic spin values, a pi...

Neutrinos, Axions and Conformal Symmetry

We demonstrate that radiative breaking of conformal symmetry (and simultaneously electroweak symmetry) in the Standard Model with right-chiral neutrinos and a minimally enlarged scalar sector induces spontaneous breaking of lepton number symmetry, which naturally gives rise to an axion-like particle with some unusual features. The couplings of this ‘axion’ to Standard Model particles, in partic...

Symmetric Spaces with Conformal Symmetry

We consider an involutive automorphism of the conformal algebra and the resulting symmetric space. We display a new action of the conformal group which gives rise to this space. The space has an intrinsic symplectic structure, a group-invariant metric and connection, and serves as the model space for a new conformal gauge theory. ∗Electronic-mail: [email protected]
