Bright solitary waves and non-equilibrium dynamics in atomic Bose-Einstein condensates
No full textIn this thesis we investigate the static properties and non-equilibrium dynamics of bright solitary waves in atomic Bose-Einstein condensates in the zero-temperature limit, and we investigate the non-equilibrium dynamics of a driven atomic Bose-Einstein condensate at finite temperature.
Bright solitary waves in atomic Bose-Einstein condensates are non-dispersive and soliton-like matter-waves which could be used in future atom-interferometry experiments. Using the mean-field, Gross-Pitaevskii description, we propose an experimental scheme to generate pairs of bright solitary waves with controlled velocity and relative phase; this scheme could form an important part of a future atom interferometer, and we demonstrate that it can also be used to test the validity of the mean-field model of bright solitary waves. We also develop a method to quantitatively assess how soliton-like static, three-dimensional bright solitary waves are; this assessment is particularly relevant for the design of future experiments.
In reality, the non-zero temperatures and highly non-equilibrium dynamics occurring in a bright solitary wave interferometer are likely to necessitate a theoretical description which explicitly accounts for the non-condensate fraction. We show that a second-order, number-conserving description offers a minimal self-consistent treatment of the relevant condensate -- non-condensate interactions at low temperatures and for moderate non-condensate fractions. We develop a method to obtain a fully-dynamical numerical solution to the integro-differential equations of motion of this description, and solve these equations for a driven, quasi-one-dimensional test system. We show that rapid non-condensate growth predicted by lower-order descriptions, and associated with linear dynamical instabilities, can be damped by the self-consistent treatment of interactions included in the second-order description

Thomas of Marga's Monastic History and Other Texts
No full textBedjan here offers in his customary manner (i.e. in fully vocalized east Syriac script) several texts: Thomas of Marga’s Monastic History of Bet ‘Abe (also known as the Book of Governors), ‘Ishodnah’s Book of Monastery Founders, Homilies on Joseph by Narsai, and a collection of texts from Leo the Great (the Tome), Nestorius, Sahdona (Martyrius), and the Testament of St. Ephrem (in a different redaction than those previously published). The volume is prefaced with an introduction in French. This range of materials will be of interest to every reader concerned with the theology and history of Syriac Christianity.Includes introduction in French
Failed Censures: Ecclesiastical Regulation of Women’s Clothing in Late Medieval Italy
No full textChurchmen in the late thirteenth and early fourteenth centuries tried to regulate the costume of Italian women.

Western medieval legal manuscripts in the collections of the University of Pennsylvania
No full textWestern legal manuscripts of the Middle Ages in North American collections are among the least known to scholars. The University of Pennsylvania has a rich collection of these texts, several of which were in the collection of the historian Henry Charles Lea. Included are works of civil law and canon law, as well as collections of papal letters and guides to pastoral care. The descriptions of most of these manuscripts in the catalog of Norman P. Zacour and Rudolf Hirsch are perfunctory, sometimes erring or omitting valuable information. Other manuscripts were added in recent years in the Lawrence J. Schoenberg Collection. Much of this material is being added to the Franklin online catalog of the University’s libraries, but researchers frequently do not search these digital resources. This article provides more complete guidance to the University’s medieval legal manuscripts than any of the existing catalogs offers, whether in print or online. It also provides updated bibliographic information in print or online. Every manuscript has been examined by the author in situ. Among the important works represented in the collection is the Panormia (a work of canon law often attributed to Ivo of Chartres). Authors present include the curialist Thomas of Capua, canonists Petrus de Braco, William of Pagula, Bernardus Raimundi, Adam of Aldersbach, Raymond of Peñafort, and civil lawyers Baldus de Ubaldis, and Bartolus de Saxoferrato. Three of these manuscripts were owned in the past by Sir Thomas Phillipps
Forbidden Colors in the Regulation of Clerical Dress from the Fourth Lateran Council (1215) to the Time of Nicholas of Cusa (d. 1464)
