Skyrmions and domain walls in (2+1) dimensions

We study classical solutions of the vector O(3) sigma model in (2+1) dimensions, spontaneously broken to O(2)xZ2. The model possesses Skyrmion-type solutions as well as stable domain walls which connect different vacua. We show that different types of waves can propagate on the wall, including waves carrying a topological charge. The domain wall can also absorb Skyrmions and, under appropriate initial conditions, it is possible to emit a Skyrmion from the wall.Comment: plain tex : 15 pages, 21 Postscript figures, uses epsf.te

Mesons, Baryons and Waves in the Baby Skyrmion Model

We study various classical solutions of the baby-Skyrmion model in $(2+1)$ dimensions. We point out the existence of higher energy states interpret them as resonances of Skyrmions and anti-Skyrmions and study their decays. Most of the discussion involves a highly exited Skyrmion-like state with winding number one which decays into an ordinary Skyrmion and a Skyrmion-anti-Skyrmion pair. We also study wave-like solutions of the model and show that some of such solutions can be constructed from the solutions of the sine-Gordon equation. We also show that the baby-Skyrmion has non-topological stationary solutions. We study their interactions with Skyrmions.Comment: plain tex : 17 pages, 14 Postscript figures, uses epsf.te

Dynamics of the topological structures in inhomogeneous media

We present a general review of the dynamics of topological solitons in 1 and 2 dimensions and then discuss some recent work on the scattering of various solitonic objects (such as kinks and breathers etc) on potential obstructions.Comment: based on the talk given by W.J.

Solitons in a Baby-Skyrme model with invariance under area preserving diffeomorphisms

We study the properties of soliton solutions in an analog of the Skyrme model in 2+1 dimensions whose Lagrangian contains the Skyrme term and the mass term, but no usual kinetic term. The model admits a symmetry under area preserving diffeomorphisms. We solve the dynamical equations of motion analytically for the case of spinning isolated baryon type solitons. We take fully into account the induced deformation of the spinning Skyrmions and the consequent modification of its moment of inertia to give an analytical example of related numerical behaviour found by Piette et al.. We solve the equations of motion also for the case of an infinite, open string, and a closed annular string. In each case, the solitons are of finite extent, so called "compactons", being exactly the vacuum outside a compact region. We end with indications on the scattering of baby-Skyrmions, as well as some considerations as the properties of solitons on a curved space.Comment: 30 pages, 5 figures, revtex, major modifications, conclusions modifie

‘All across Europe it had come’: The Black Death and Fascism in Sylvia Townsend Warner’s The Corner That Held Them

Sylvia Townsend Warner’s wartime novel The Corner that Held Them (1948), about a nunnery during the Black Death, reflects on female community and bonding in a period of male fascist violence. The novel explores the shift from pacifism to acceptance of the need for anti-fascist war which characterised Warner’s intellectual beliefs from the 1930s into wartime, probing the arts of peace in compositional practice. Such a dialectic of war and peace is considered in relation to what Maud Ellmann has described as the outward turn to collective choral consciousness in mid-century modernism. This article explores both the staging of fascism as plague and the feminist daring and limits that Warner saw as operative in female witnessing and withstanding of Nazi ideology and menace. It closely reads key scenes from the panorama of a novel (notably Alianor’s stillness as her husband is killed, Alicia’s plans to withstand the economic impact of the Black Death and the cure of Ralph’s plague symptoms) to register the satirical and allegorical substance of Warner’s rescripting of Woolfian notions of resistance to warmongering misogyny by a society of outsiders. The readings seek to consolidate a varied and multiple sense of the book as a Marxist historical novel that gives voice to the ruled. In doing so Warner analyses the Black Death as a moment in history that saw the emergence of early modern capitalism and labour relations out of the feudal system, even as the religious framework that had structured medieval Europe gave way to more secular beliefs in autonomy, self-determination, citizen and collective dreams, projects and affects. At the same time the plague as a political trope, rooted in anti-fascist rhetoric that turns Nazi anti-Semitic uses of the Black Death motif on their head, triggers readings that bring those historical scenes into allegorical relation with the ways in which the Second World War was experienced by marginalised female communities
