Representation and self-presentation in late antique Egypt: ‘Coptic’ textiles in the British Museum

Modern Akhmim was a productive source of “Coptic” textiles entering international collections in the late nineteenth century. Fragments said to have come from the site constitute the majority of registered textiles held by the Ancient Egypt and Sudan Department, The British Museum. In Late Antiquity, Akhmim was the location of Panopolis/Shmin, one of about forty metropoleis and a city relatively well documented in contemporary textual and other archaeological sources. This is precisely the period in which most of Egypt’s residents became Christian. The abundance of material culture representing Panopolis/Shmin provides an opportunity to explore and challenge the categories scholars have traditionally used to describe late antique Egypt: Christian/pagan, rural/urban, poor/wealthy, Coptic/Greek. This paper will establish the grounds for attributing the BM corpus to the site; discuss the context of their ancient production and function; and explore the expression of cultural and personal identity via textiles, arguing for conservatism in religious and burial practice in late antique Egypt

Intersubband-cyclotron combined resonance in a surface space-charge layer

In a magnetic field tilted with respect to the surface of Si, combined resonance transitions have been observed, resulting from a coupling of Landau levels and subband states. Because of some unexplained features in the observations, we analyze what one should expect on theoretical grounds. We conclude that unexplained discrepancies between theory and experiment still exist, which may indicate that collective effects are playing a role. © 1981

One-dimensional hydrogenic atom in an electric field with solid-state applications

A Hamiltonian describing a one-dimensional Coulomb field with an electric field in the same direction is useful for the discussion of electrons outside a free surface of liquid helium [1,2] and also for the study of far-infrared emission from Si inversion layers [3]. We present both a semi-classical and a WKB solution to the problem, which exhibits many of the features found experimentally. © 1977
