Abstract : Considering the unphysical result obtained in the calculation of thefree-energy cost for twisting the boundary conditions in a spin glass, wetrace it to the negative multiplicities associated with the Parisireplica-symmetry breaking RSB. We point out that a distinct RSB, that keepspositive multiplicities, was proposed long ago, in the spirit of anultra-long time dynamical approach due to Sompolinsky. For an homogeneousbulk system, both RSB schemes are known to yield identical free energiesand observables. However, using the dynamical RSB, we have recalculatedthe twist free energy at the mean-field level. The free-energy cost of thistwist is, as expected, positive in that scheme, as it should.
