Silent translation in Joyce
No full textFocusing on the notion of silent translation, i.e. the unacknowledged incorporation of translated texts into one’s writing, this chapter calls attention to the inherently translational nature of Joyce’s use of intertextuality. The silent operations carried out by Joyce in dealing with other writers’ words in translation are thus investigated. The author suggests that silent translation should be viewed as one of the key components of Joyce’s radically intertextual writing method, a strategy he made use of to question the traditional notions of originality and derivation
Light-matter interaction in photonic metasurfaces
No full textIn the present work, we discuss the properties of the complex (i.e., including real and
imaginary part of the eigenvalues) eigenmodes in dielectric photonic metasurfaces. These
structures are usually composed of a multi-layered waveguide core with a generic in-
plane periodic patterning. The presence of active materials, i.e. materials sustaining
excitonic resonances, can result in the so-called radiation-matter strong-coupling regime.
This phenomenon manifests itself with the formation of the elementary excitations called
exciton-polaritons, for brevity only polaritons. The study of these elementary excitations is
motivated from either an application point of view, or a fundamental interest. Indeed, these
elementary excitations in solids can serve as a platform for the study of various exotic
states of matter. For example, polaritons can display superfluid behaviour and undergo
Bose-Einstein condensation at relatively high temperature. On the other hand, one of the
final goals of this research field is to replace electrons with photons and polaritons as
information carriers in circuits. In this thesis, we ultimately studied the dispersions, losses,
symmetry and topological properties of either photons or polaritons in the aforementioned
metamaterials. The control over these quantities are essentials for any targeted application.
Throughout the thesis, several algorithms have been used to investigate the physics
of the elementary excitations in metasurfaces, such as the guided mode expansion, the
scattering matrix (or rigorous coupled wave analysis) and the finite-difference time-domain
methods. Most of the theoretical predictions presented in this thesis are validated by
experimental measurements. As the main original contribution, we extended the quantum
theory of light-matter coupling to metasurfaces coupled with an arbitrary number of active
layers. Thanks to the newly introduced theory, it is possible to take into account either
classical active multi quantum well systems, or two dimensional semiconductor materials
and perovskite layers coupled with the photonic modes. We compared the results of the
generalised theory with semi classical results, and experiments. In each case, we obtained
a good agreement for both the real dispersions of the polaritonic modes and the losses.
In addition, we studied the symmetry and topological properties of bound states in the
continuum (BICs). The BIC is a peculiar type of solution of the wave equation, in this
case Maxwell equations, that is perfectly confined despite the fact it lives in a continuum
of radiative solutions. Among its exotic properties, we can identify its singularity in
the far-field emission pattern, resulting in a polarisation of electromagnetic radiation.
We demonstrated that this topological singularity can be transferred to BIC coupled to
excitons, namely polaritonic-BIC (pol-BIC). Finally, we studied a platform where the
non-linear polariton-polariton scattering processes create a trap for the pol-BIC leading to
Bose-Einstein phase transition with extremely low condensation threshold.In the present work, we discuss the properties of the complex (i.e., including real and

From Suspicion to Trust: The ‘Pact of Translation’ in Two Author-Translator Collaborations
No full textThere is a vast literature showing that author-translator relationships are often fraught with tensions which undermine trust between the two parties (Anokhina 2017; Hersant, 2017, 2020). These tensions are hardly detectable from the sole comparison of source and target texts but are likely to be revealed in archival material such as editorial correspondence or revised translator’s typescripts and galley proofs. The examination of archival material makes it possible to observe how trust between translator and author develops and deepens, but also how it can be jeopardized when other intermediaries come into play. This paper focuses on documents taken from the Lilly Library at the University of Indiana Bloomington. Both epitextual sources (such as correspondence with publishers and authors) and genetic sources (such as translators’ manuscripts and notebooks) pertaining to translators William Weaver (1923-2012) and Barbara Wright (1915-2009) are examined, with a view to better understand the complex interplay of trust and mistrust that takes place in translation collaborations

The reception of Max Weber's Cubist Poems (1914) in Taishō Japan
No full textIn this paper, I will analyze the Japanese reception of Cubist Poems, a collection of experimental poetry published in 1914 by the Jewish-American painter Max Weber (1881‒1961). First, I will provide information on this little-known collection and its author. Then I will offer a general description of the structure of the field of cultural production in 1910s and 1920s Tokyo, a period that roughly corresponds to the reign of Emperor Taishō (1912‒1926). To do so, I will use a number of theoretical tools from the works of Pierre Bourdieu. Part of this article will be structured as a historical survey of the presentation of Cubist Poems in 1914‒1925 Japan. As will become clear, in the Japanese cultural world, Weber’s collection provoked an interest that was unparalleled in any other country, perhaps even in the English-speaking world. Finally, I will offer some interpretations of the characteristics of this reception and some hypotheses concerning its causes
"La città è un motore e il suo cuore è una dinamo-elettrica": considerazioni sul futurismo di Hirato Renkichi (1894?-1922)
No full textHirato Renkichi (1894?-1922) is mainly remembered as the author of the Japanese Futurist Manifesto (Nihon Miraiha sengen undō, autumn 1921). In this paper I present an outlook on the Japanese studies on this poet, and then I venture into a more original overview of his theoretical essays. My main goal is to give a historical and comparative perspective on the works of this almost forgotten Japanese Futurist.
The first part is a survey on the actual contacts Hirato had with artists connected to the then-rising Japanese Avant-garde Movement.
In the second part, I focus on his Manifesto and on two other essays (“Watashi no miraishugi to jikkō” and “Anarojizumu ni tsuite”) in order to show what Hirato took (or did not take) from Filippo Tommaso Marinetti’s manifestos, and to enucleate his original contribution to Futurist discourse
Dynamite Against the Bundan: Fantasies of Empowerment and Violence in the Writings of Yamamura Bochō
No full textThis study investigates the strategies of empowerment within the literary field that were adopted by Yamamura Bochō (1884-1924), an author of shi
(poetry in non-traditional forms) who ephemerally came to the fore of the Japanese literary scene (bundan) with the collection "Seisanryōhari"
(The Holy Prism), published in 1915. It is focused on Bochō's articulation of a fantasy of empowerment by destruction and regeneration: such tropes are similar to the rhetorical strategies adopted by the European avant-garde movements, and, in evoking such categories as ‘terrorism’ or ‘anarchism’, they border the domains of early 20th century political discourse. These tropes are analyzed focusing on a genealogical perspective that involves both intertextual and historical research. It is argued that the rhetoric of antagonism and destruction can be a relevant
focus in order to appreciate the modalities of construction of a modernist discourse from both a Japanese and comparative perspective.
