Double Λ Hypernuclei and the Λ-λ Interaction. *
We approximate the double Λ hypernuclei by systems composed by two interacting Λ’s moving in the mean field potential created by the nuclear cores. The Λ-core potentials are adjusted to reproduce the binding energies of the corresponding single Λ hypernuclei [1]. A σ-ω meson exchange potential [2] is used for the Λ-Λ interaction. We apply both the Hartree-Fock (HF) and variational approximation...
متن کاملWeak Transition in Double-Λ Hypernuclei
We calculate the ΛΛ → Y N transition rate of 6 ΛΛHe by the hybrid picture, the π and K exchanges plus the direct quark processes. It is found that the hyperon-induced decay is weaker than the nucleon-induced decay, but the former may reveal the short-range mechanism of the weak transition and also give a clear signal of the strong ∆I = 3/2 transition. The ΛΛ → YN transition in double-Λ hypernuc...
متن کاملComputing all Pairs (λ, μ) Such That λ is a Double Eigenvalue of A+μB
Double eigenvalues are not generic for matrices without any particular structure. A matrix depending linearly on a scalar parameter, AþμB, will, however, generically have double eigenvalues for some values of the parameter μ. In this paper, we consider the problem of finding those values. More precisely, we construct a method to accurately find all scalar pairs ðλ;μÞ such that AþμB has a double...

متن کاملDouble entanglement and quantum cryptography
We propose a quantum transmission based on bi-photons which are doubly-entangled both in polarisation and phase. This scheme finds a natural application in quantum cryptography, where we show that an eventual eavesdropper is bound to introduce a larger error on the quantum communication than for a single entangled bi-photon communication, when he steels the same information.
