Rotational Doppler shift of the phase-conjugated photon
The rotational Doppler shift of a photon with orbital angular momentum is shown to be an even multiple of the angular frequency
of the reference frame rotation when photon is reflected from the
phase-conjugating mirror. We consider the one-arm phase-conjugating
interferometer which contains Dove prisms or other angular momentum
altering elements rotating in opposite directions. When such interferometer is
placed in the rotating vehicle the
rotational Doppler shift appears and rotation of the helical interference
pattern with angular frequency occurs. The
accumulation of angular Doppler shift via successive passage through the
image-inverting prisms is due to the phase conjugation, for conventional
parabolic retroreflector the accumulation is absent. The features of such a
vortex phase conjugating interferometry at the single photon level are
discussed.Comment: 6 pages, 3 figures, submitted to referred journa

How to humiliate and shame: A reporter's guide to the power of the mugshot
This is an Author's Accepted Manuscript of an article published in Social Semiotics, 24(1), 56-87, 2014, copyright Taylor & Francis, available online at: http://www.tandfonline.com/The judicial photograph – the “mugshot” – is a ubiquitous and instantly recognisable form, appearing in the news media, on the internet, on book covers, law enforcement noticeboards and in many other mediums. This essay attempts to situate the mugshot in a historical and theoretical context to explain the explicit and implicit meaning of the genre as it has developed, focussing in particular on their use in the UK media in late modernity. The analysis is based on the author's reflexive practice as a journalist covering crime in the national news media for 30 years and who has used mugshots to illustrate stories for their explicit and specific content. The author argues that the visual limitations of the standardised “head and shoulders” format of the mugshot make it a robust subject for analysing the changing meaning of images over time. With little variation in the image format, arguments for certain accreted layers of signification are easier to make. Within a few years of the first appearance of the mugshot form in the mid-19th century, it was adopted and adapted as a research tool by scientists and criminologists. While the positivist scientists claimed empirical objectivity we can now see that mugshots played a part in the construction of subjective notions of “the other”, “the lesser” or “sub-human” on the grounds of class, race and religion. These dehumanising ideas later informed the theorists and bureaucrats of National Socialist ideology from the 1920s to 1940s. The author concludes that once again the mugshot has become, in certain parts of the media, a signifier widely used to exclude or deride certain groups. In late modernity, the part of the media that most use mugshots – the tabloid press and increasingly tabloid TV – is part of a neo-liberal process that, in a conscious commercial appeal to the paying audience, seeks to separate rather than unify wider society
Geometric phase effects for wavepacket revivals
The study of wavepacket revivals is extended to the case of Hamiltonians
which are made time-dependent through the adiabatic cycling of some parameters.
It is shown that the quantal geometric phase (Berry's phase) causes the revived
packet to be displaced along the classical trajectory, by an amount equal to
the classical geometric phase (Hannay's angle), in one degree of freedom. A
physical example illustrating this effect in three degrees of freedom is
mentioned.Comment: Revtex, 11 pages, no figures
Interpretation, 1980 And 1880
This article reviews recent methodological interventions in the field of literary study, many of which take nineteenth-century critics, readers, or writers as models for their less interpretive reading practices. In seeking out nineteenth-century models for twenty-first-century critical practice, these critics imagine a world in which English literature never became a discipline. Some see these new methods as formalist, yet we argue that they actually emerge from historicist self-critique. Specifically, these contemporary critics view the historicist projects of the 1980s as overly influenced by disciplinary models of textual interpretation models that first arose, we show through our reading of the Jolly Bargemen scene in Charles Dickens\u27s Great Expectations (1860 61), in the second half of the nineteenth century. In closing, we look more closely at the work of a few recent critics who sound out the metonymic, adjacent, and referential relations between readers, texts, and historical worlds in order sustain historicism\u27s power to restore eroded meanings rather than reveal latent ones
Geometric phase and o-mode blue shift in a chiral anisotropic medium inside a Fabry-P\'erot cavity
Anomalous spectral shift of transmission peaks is observed in a
Fabry--P\'erot cavity filled with a chiral anisotropic medium. The effective
refractive index value resides out of the interval between the ordinary and the
extraordinary refractive indices. The spectral shift is explained by
contribution of a geometric phase. The problem is solved analytically using the
approximate Jones matrix method, numerically using the accurate Berreman method
and geometrically using the generalized Mauguin--Poincar\'e rolling cone
method. The -mode blue shift is measured for a
4-methoxybenzylidene-4'--butylaniline twisted--nematic layer inside the
Fabry--P\'erot cavity. The twist is electrically induced due to the
homeoplanar--twisted configuration transition in an ionic-surfactant-doped
liquid crystal layer. Experimental evidence confirms the validity of the
theoretical model.Comment: the text is available both in English (Timofeev2015en.tex) and in
