Microwave conductivity of d-wave superconductors with extended impurities

We investigate the influence of extended scatterers on the finite temperature and finite frequency microwave conductivity of d-wave superconductors. For this purpose we generalize a previous treatment by Durst and Lee, which is based on a nodal approximation of the quasiparticle excitations and scattering processes, and apply it to the analysis of experimental spectra of YBCO-123 and BSCCO-2212. For YBCO, we find that accounting for a slight spatial extension of the strong scattering in-plane defects improves the fit of the low temperature microwave conductivity to experiment. With respect to BSCCO we conclude that it is necessary to include a large concentration of weak-to-intermediate strength extended scatterers, which we attribute to the out-of plane disorder introduced by doping. These findings for BSCCO are consistent with similar analyses of the normal state ARPES spectra and of STM spectra in the superconducting state, where an enhanced forward scattering has been inferred as well.Comment: 10 pages, 11 figure

Cypriots to the West? The Evidence of Their Potmarks

Three amphora handles (Fig. 1), of Mycenaean type, bear the only possible traces of Cypriot writing found in Bronze Age Italy, and they are the only known possible direct traces of Cypriot participation in trade with the western Mediterranean in the Late Bronze Age. In this paper, I proceed first with a brief description of the marked handles and their provenience; second, I illustrate their Cypriot associations; and finally I discuss possible implications of this identification

Eastwards via Cyprus? The Marked Mycenaean Pottery of Enkomi, Ugarit and Tell Abu Hawam

Based on her study of distribution patterns, Vronwy Hankey suggested that Cyprus or Cypriots played some role in the trade of Mycenaean pottery eastwards to the Levant. She also noted that some of the Mycenaean pottery which reached both Cyprus and the Near East carried marks incised on handles or painted on bases. This paper examines the possible relationships between the marks, Mycenaean pottery, Cyprus, and the trade in Late Bronze Age ceramics. Special reference is made to the evidence from the sites of Enkomi, Ugarit, and Tell Abu Hawam. À partir de son étude sur les schémas de répartition, Vronwy Hankey a suggéré que Chypre, ou des Chypriotes, avaient joué un rôle dans le commerce de la céramique mycénienne en direction du Levant. Elle avait aussi remarqué qu\u27une partie de la céramique mycénienne qui était arrivée tant à Chypre qu\u27au Proche-Orient portait des marques incisées sur l\u27anse ou peintes sur la base des vases. Cette communication examine les liens possibles entre ces marques, la céramique mycénienne, Chypre et le commerce de céramique à l’âge du Bronze Récent. Une attention spéciale est portée aux données fournies par les sites d\u27Enkomi, Ougarit et Tell Abou Hawam

Vases Marked for Exchange: The Not-So-Special Case of Pictorial Pottery

Large, bold marks are painted or incised on the handles or bases of thirty-seven pictorial vases. These same kinds of marks and same patterns of marking are found on non-pictorial Mycenaean pottery. In general, marks on Mycenaean pottery are rare and the circumstances of their use are not yet fully understood. It is clear that they are associated with Cyprus, and it is most likely that they are associated with Cypriot traders. The marks do indicate that pictorial vases were handled through the same channels and documented in the same manner as the trade in linear and pattern-decorated Mycenaean pottery

Appendix K: Trireme Warfare in Xenophon’s Hellenika

The disaster at Syracuse (415-413) marked the effective end of Athenian naval supremacy. She would rebuild her fleets and continue to be a force, but Xenophon\u27s account of the following half century tells of a hard-fought struggle among many contenders to dominate the Aegean Sea. Although in the ancient Mediterranean world geography and tradition favored islands and coastal cities as emergent sea powers, dominance could not be achieved without also having access to the vital resources of timber, manpower, and plenty of revenue. Thus the Persian king Artaxerxes and Jason of Pherai posed alarming threats to the traditional masters of the Aegean. Athens, Sparta, and reportedly the Phoenicians managed on occasion to raise fleets of two or even three hundred warships, but mostly the seas were dotted with much smaller flotillas that nevertheless effectively patrolled, threatened, or deterred.

Joan du Plat Taylor: The Road to Apliki

Thirty-two-year-old Joan du Plat Taylor and her friend Judith Dobell [Stylianou] must have created a stir when they arrived at the field offices of the Cyprus Mining Corporation in 1938. For one thing, Joan probably drove, and the sight of an English-woman driving would have been cause enough for comment among the villagers. The few photographs of Joan\u27s cars which survive depict vehicles overflowing with the accoutrements of field excavation, large bundles tied to the roof and hanging off the rear of the wagon. And always dogs perched among the piles of baggage. The road up the Marathasa Valley was not paved, and women and dogs and bumping bundles must have presented a dusty, raucous show as they lurched their way through small villages on the way to the mines

Appendix IV: Potmarks

I. Potmarks from the Limassol area tombs The excavation of any Late Cypriote site settlement, tomb, shipwreck usually yields pottery marked with incised, impressed, or painted signs. The collection of marked pottery presented here is significant especially because it fills in the heretofore geographic lacuna between the substantial assemblages of Late Cypriote potmarks discovered in the Kouris (Smith 2012) and Vasilikos (E. Masson 1989; Cadogan, Driessen, and Ferrara 2009, 145) River Valleys. Smith has demonstrated how much marked pottery, considered in the context of other indications of administrative control, can reveal about the administrative, economic, and political organization of a region. The Vasilikos Valley merits similar treatment. In between there are now these twenty-eight marked vases from the Limassol district too few to indicate clearly how this region fitted into or rubbed against the marking practices used by its neighbours, but a start and, it is hoped, a promise of more

Cypriots in the Mycenaean Aegean

Many different types of evidence provide clues to the nature of commercial exchange among the regions of the Late Bronze Age eastern Mediterranean. I approach this topic through the study of marks which were incised or painted on pottery traded between the Near East and the Aegean. Thanks to the kindness of many excavators and museum officials in Cyprus and Greece, I have been able to examine firsthand much of the marked pottery found in those regions
