On the impact of large amplitude pairing fluctuations on nuclear spectra

The influence of large amplitude pairing fluctuations is investigated in the framework of beyond mean field symmetry conserving configuration mixing calculations. In the numerical application the finite range density dependent Gogny force is used. We investigate the nucleus ⁵⁴Cr with particle number and angular momentum projected wave functions considering the axial quadrupole deformation and the pairing gap degree of freedom as generator coordinates. We find that the effects of the pairing fluctuations increase with the excitation energy and the angular momentum. The self-consistency in the determination of the basis states plays an important role.     

Erratum to “The extended Higgs system in R-symmetric supersymmetry theories” [Phys. Lett. B 697 (2011) 215]

We correct Fig. 1(right) of S.Y. Choi et al. (2011) [1] illustrating the neutralino masses in the R-symmetric model.     

Erratum to “Entanglement in eight-qubit graph states” [Phys. Lett. A 373 (2009) 2219]

Some errors are corrected.     

Erratum to: “Comment on: ‘Electromagnetic wave propagation in single-wall carbon nanotubes’ [Phys. Lett. A 333 (2004) 303]” [Phys. Lett. A 364 (2007) 515]

Here we plot the correct form of Fig. 2 in [H. Khosravi, A. Moradi, Phys. Lett. A 364 (2007) 515].     

Comment on: “Questions concerning the generalized Hartman effect” [Phys. Lett. A 375 (2011) 3259]

In this comment, we show that the arguments against the applicability of stationary phase method (SPM) for tunneling time calculations, presented in Letter “Questions concerning the generalized Hartman effect” are not valid for small wave packet energy widths.

A typographical error has been corrected.
