Napoleon’S Corpse And The Subversion Of Historical And Political Authority, Alissa Rachel Adams

Art Inquiries

This article examines printed depictions of Napoleon Bonaparte’s exhumed corpse in conjunction with Romantic historical practice in nineteenth-century France. Current studies on history in the Romantic age emphasize Romantic historicism’s link to a widespread and frustrated yearning for direct access to the past that will settle the upheavals of the revolutionary period. This study considers how the corpse and its representations fulfill the desire for direct access to the past but, in doing so, also contributes to a proliferation of individual understandings of the past—and future. Through an analysis of representations of the corpse, their sources, and their connection to …

A New Form Of Soft Supersymmetry Breaking?, Scott Chapman

Mathematics, Physics, and Computer Science Faculty Articles and Research

Starting with a supersymmetric U(N) × U(N) gauge theory built in N = 1 superspace, a nonsupersymmetric theory is obtained by “twisting” the gauginos into a different representation of the group than the gauge bosons. Despite the fact that this twisting breaks supersymmetry, it is still possible to construct an action that is holomorphic and invariant to local “twisted” gauge transformations in superspace. It is conjectured that these two properties may allow the theory to be free of quadratic divergences to all orders, despite a lack of supersymmetry. An explicit calculation shows that the theory is free of quadratic divergences …
