Performance Text

The critical field of The Masque of Blackness often annotates Queen Anne and her ladies’ blackface performance with a courtier's eye-witness comment that the “lean cheeked moors” were “loathsome” and “ugly.” Yet Ben Jonson's performance text, when read beside Dudley Carleton's correspondences, resists the undue influence of the aristocrat's anecdotal disparagement. This project refuses to take Carleton's denigration as fact. Instead, it investigates the masque's representation of Niger's daughters to develop the affective experience of pleasurable mixing across racial identities and to show how the opulence, innovation, and beauty afforded by blackface are the means to underwrite arguments of political authority. Rather than a deviation from the performance's magnificent appeal, racial impersonation is constitutive of the masque's demonstration of beauty and invention of pleasure. As such, the allegory of King James I's power hinges on a fiction of idealized incorporation that is ideologically powerful precisely because it is primarily an aestheticized, affective experience. Beyond the ostensible trope of racial transformation, Jonson presents the pleasure of mixing across racial identities as the precondition for Britannia's absorption of migrant bodies. Blackness is a visual reminder of an indelible difference that can be absorbed, incorporated, indeed “salved,” by the monarch's faculties of conversion. The affective experience afforded by blackface is thus an argument for the sovereign's power of unification, underwriting what was a largely unfulfilled and controversial political agenda: the coalition of realms under the aegis of Great Britain.

Anomalous Nernst Effect

The transverse voltage generated by a temperature gradient in a perpendicularly applied magnetic field, termed the Nernst effect, has promise for thermoelectric applications and for probing electronic structure. In magnetic materials, an anomalous Nernst effect (ANE) is possible in a zero magnetic field. We report a colossal ANE in the ferromagnetic metal UCo0.8Ru0.2Al, reaching 23 microvolts per kelvin. Uranium’s 5f electrons provide strong electronic correlations that lead to narrow bands, a known route to producing a large thermoelectric response. In addition, uranium’s strong spin-orbit coupling produces an intrinsic transverse response in this material due to the Berry curvature associated with the relativistic electronic structure. Theoretical calculations show that in UCo0.8Ru0.2Al at least 148 Weyl nodes, and two nodal lines, exist within 60 millielectron volt of the Fermi level. This work demonstrates that magnetic actinide materials can host strong Nernst and Hall responses due to their combined correlated and topological nature.
