Higgs response and pair condensation energy in superfluid nuclei

Abstract The pairing correlation in nuclei causes a characteristic excitation, known as the pair vibration, which is populated by transfer reactions. Here we introduce new method of characterizing vibration employing an analogy to Higgs mode, emerges infinite superconducting/superfluid systems collective vibrational mode associated with amplitude oscillation Cooper condensate. idea formulated defining pair-transfer probe, operator, and then describing linear response strength function this probe. We will show that condensation energy can be extracted use sum static polarizability response. In order demonstrate validate method, perform for Sn isotopes numerical analysis based on quasi-particle random phase approximation Skyrme-Hartree-Fock-Bogoliubov model. discuss possibility apply scheme experiment.
