Within path integral model of d-pairing for heavy-fermion superconductors (HFSC) developed recently by Brusov and Brusova-Kulik, the whole collective mode spectrum has been calculated for three states of HFSC. Among them, two states (dγ and Y2−1) have been treated by Hiroshima and Namaizawa before, while the third state is considered for the first time. The number of collective modes in each phase is equal to ten,among which five are high-frequency modes while the five others are Goldstone or… CONTINUE READING
