Andrew J. Rotter, Hiroshima – The Word’s Bomb
No full textO livro Hiroshima – The world’s bomb de Andrew J. Rotter descreve, sob várias perspetivas, um dos incidentes mais marcantes do século XX. O alcance das bombas atómicas lançadas sobre o Japão deu a conhecer ao mundo uma arma com um poder destrutivo de tal ordem que Estados em guerra se poderiam destruir mutuamente em segundos. A ameaça atómica esteve no centro de um dos conflitos mais longos do século XX – a Guerra Fria – e está, ainda hoje, no centro de vários conflitos entre potências region..

Fisher Information in Electromagnetism
No full textIn my talk, I will discuss recent progress in applying the concept of classical and
quantum Fisher informa;on to the problem of estimating system parameters in
electromagnetic scattaering and nano-photonics. Specifically, I will demonstrate how Fisher Information can be maximised through wavefront shaping and quantum state engineering [1,2]. Quite interestingly, the density and flux of Fisher information satisfy a fundamental continuity equation – in analogy to the Poynting theorem for the density and flux of energy in a radiation field [3]. This viewpoint allows us to identify Fisher information a physical quantity that propagates through space and that can resonate, diffract, and interfere [4]. Finally, I will also say a few words about how such concepts can be generalised to the flow of Fisher Information through Artificial Neural Networks [5].

Beloved: a political composition
No full textThe emergent term, traumatic fiction describes the extraordinary violence inflicted on individuals and groups during a traumatic twentieth-century history which encompasses two world wars, various genocides, the Great Depression, and the Cold War. Traumatic fiction narratives mirror the neurosis of traumatic experience by distorting conventional narrative structures and using literary techniques like fragmentation, textual gaps, and repetition. They critique the social, economic, and political structures which make and maintain trauma. Traumatic fiction narratives focus on the problems of amnesia and memory in the construction of the historical narrative. It questions a "true" historical narrative by focusing on traditionally suppressed voices. Toni Morrison's novel, Beloved (1987) exemplifies this genre of traumatic fiction. However, critics have confused Toni Morrison's traumatic fiction writing style with music. Critics like Lars Eckstein, Peter J. Capuano, and Joanna Wolfe focus their analysis on Morrison's "jazzthetic" quality or the novel's similarities to a slave song; they also argue that the numerous songs incorporated in the novel make the musical quality of her writing essential to understanding this novel. By focusing on the supposed musical quality of her writing, critics have missed Morrison's political purpose. This paper argues that Beloved shows that the dominant white culture, historically contemptuous of the black experience, defines slavery in ways that create trauma for black Americans. Traumatic fiction, it suggests, allows Morrison to access the past and rewrite slavery's narrative. Traumatic techniques allow Morrison to transform her readers into co-witnesses so that a victim's trauma can be externalized, giving the victims much-needed distance from their trauma. That distance allows victims to revisit, reflect, rework, and retell history from a black perspective in order to transcend shame of slavery imposed by white society. Morrison uses traumatic fiction techniques because they provide a language, unmarked by white discourse, for Morrison to tell a black story of slavery that resists forgetting and silencing. Morrison challenges the seemingly authenticated historical story that upholds individualism in order to create room for a new black cultural memory that highlights community, which is its true story.M.A.Includes bibliographical referencesby Kimberly Rose Rotte
The concept of Fisher information in wave scattering
No full textIn my talk, I will discuss recent progress in applying the concept of classical and quantum Fisher information to the problem of estimating system parameters in complex environments, such as inside or behind a disordered medium. In particular, I will demonstrate how Fisher Information can be maximised through wavefront shaping and quantum state engineering [1,2]. Quite interestingly, the density and flux of Fisher information satisfy a fundamental continuity equation – in analogy to the Poynting theorem for the density and flux of energy in a radiation field [3]. If time permits, I will also say a few words about how such concepts can be generalised
to the flow of Fisher Information through Artificial Neural Networks.

Non-Hermitian Topology in Lasers and Anti-Lasers
No full textn my presentation, I will first speak about the topological aspects of encircling an exceptional point (EP) in a laser and the corresponding chiral state transfer [1]. Building on the insight that EPs can also be identified in the absorption spectra of anti-lasers [2], I will present experimental results on the chiral and degenerate perfect absorption at an EP [3]. Finally, I will show how not only two modes can be critically coupled, but more than a thousand – leading to a massively degenerate coherent perfect absorber for arbitrary incoming wavefronts [4].

Coherent perfect absorption and emisson of light in non-Hermitian and time-varying media
No full textIn this talk, I will speak about our recent work on coherent perfect absorption (CPA) [1,2] and emission [3] of light in tailor-made resonators. I will highlight, in particular, the possibility to engineer spatial and spectral degeneracies for broadband absorption of arbitrary wavefrontsat an exceptional point as well as the topological aspects associated with perfect emission of thermal radiation. In the second part of my presentation, I will present new insights on the CPA effect in time-varying media, which can be well described by a pseudo-unitary Floquet scattering matrix [4].
