“…However, we note that the calculations reported in Ref. 16] do not describe the data of Lussier et al 10 accurately in the low-temperature region, T < 0:3T c , for either pairing symmetry; the data of Lussier et al 10 for =T does not exhibit the saturation shown in the theoretical curves of Ref. 16], which assume a scattering rate of order 0 = 0:1 T c .…”

“…In our comparison of theory with experiment we pursue a di erent approach than Norman and Hirschfeld. 16 Instead of examining the e ects of the multi-sheet (LDA) Fermi surface on the heat current, we model the excitation spectrum by an excitation gap that opens at line (ab plane) and point (c axis) nodes on the Fermi surface, and by the Fermi surface properties in the vicinity of the nodes (i.e., the Fermi velocities near the nodes). The low-temperature behavior of the transport coe cients probes `lower-dimensional' regions of the Fermi surface, where the excitation gap vanishes, and is less sensitive to the overall geometry of the Fermi surface.…”

“…The authors quali ed this conclusion because their calculations assumed a spherical Fermi surface and lowest order spherical harmonics for the pairing basis functions. Very recently, Norman and Hirschfeld 16 carried out numerical calculations of the electronic thermal conductivity using a Fermi surface for UPt 3 constructed from local density approximation (LDA) calculations, and several models for the pairing basis functions (e.g., tight-binding functions and Fermisurface harmonics). These authors found considerable improvement between theory and experiment for the absolute magnitudes of ?…”

In the above paper there is an error in Fig. 4, where the thermal conductivity is plotted for an E2, pairing state for various scattering phase shifts ~0. For intermediate phase shifts ((~0 = 30 ~ and 60 ~ the curves n/T showed an exaggerated nonmonotonic behavior at low temperatures, just above the crossover temperature of the universal low temperature region. The correct results show only a weak nonmonotonic behavior or none at all. as illustrated below. All other results and conclusions remain unchanged.

We study the thermal conductivity within the E 1g and E 2u models for superconductivity in UPt 3 and compare the theoretical results for electronic heat transport with recently measured results reported by Lussier, Ellman and Taillefer. The existing data down to T=T c 0:1 provides convincing evidence for the presence of both line and point nodes in the gap, but the data can be accounted for either by an E 1g or E 2u order parameter. We discuss the features of the pairing symmetry, Fermi surface, and excitation spectrum that are re ected in the thermal conductivity at very low temperatures. Signi cant di erences between the E 1g and E 2u models are predicted to develop at excitation energies below the bandwidth of the impurity-induced Andreev bound states. The zero-temperature limit of theĉ axis thermal conductivity, lim T !0 c =T , is universal for the E 2u model, but non-universal for the E 1g model. Thus, impurity concentration studies at very low temperatures should di erentiate between the nodal structures of the E 2u and E 1g models.

Perilaku pro-lingkungan berkaitan dengan sikap dan tindakan yang mendorong individu untuk terlibat dalam perlindungan dan pelestarian lingkungan hidup. Perilaku ini sangat relevan dalam mengatasi masalah lingkungan khususnya penumpukan sampah plastik, terutama di kalangan generasi muda yang akan merasakan dampak besar dari degradasi lingkungan. Penerapan perilaku pro-lingkungan didorong oleh berbagai faktor, antara lain terpaan media, keterhubungan dengan alam, motivasi perlindungan, dan pengetahuan lingkungan. Kajian ini untuk mengetahui faktor-faktor yang memengaruhi perilaku pro-lingkungan di kalangan pemuda Jakarta Pusat. Metode penelitian adalah survei menggunakan kuesioner yang disebarkan kepada 96 pemuda berusia antara 18 hingga 30 tahun yang berdomisili di kawasan Johar Baru, Jakarta Pusat. Teknik pengambilan sampel menggunakan cluster dan accidental. Data primer yang telah diperoleh sianalisis secara deskriptif dan inferensial. Hasil penelitian menunjukkan bahwa faktor pendorong perilaku pro lingkungan pemuda adalah terpaan media, motivasi perlindungan, dan pengetahuan lingkungan. Sedangkan, keterhubungan dengan alam dapat menjadi faktor lain namun membutuhkan mediasi motivasi perlindungan.
