Cross-Kerr interaction in a four-level atomic system
We derive the form of the cross-Kerr interaction in a four-level atomic
system in the N-configuration. We use time-independent perturbation theory to
calculate the eigenenergies and eigenstates of the Schrodinger equation for the
system. The system is considered as a perturbation of a Raman resonant
three-level lambda scheme for which exact solutions are known. We show that
within the strong control field limit the cross-Kerr interaction can arise
between two weak probe fields. The strength of this nonlinear coupling is
several orders of magnitude larger than that achievable using optical fibres.Comment: 5 pages, resubmitted to Physical Review A with clarified style and

Spaces, Emotion and Heavy Metal Subcultural Control: Music Consumption and Civilising Processes.
Despite the longevity, cultural relevance and global popularity of heavy metal, it has been noticeably absent from both the Birmingham Schoolâs subcultural studies, the Centre for Contemporary Cultural Studies (CCCS) and in consumer community contexts informed by post-subcultural perspectives (e.g., neo-tribes). This study examines the Irish heavy metal scene. The literature review considers the problematic aspects of applying both frameworks (subcultural and post-subcultural) to heavy metal and other similar contexts. I argue that Norbert Eliasâs figurational sociology (relatively underutilised in previous consumer research), can be used to bypass the agencyâstructure dualism that impedes both approaches. It is also advanced that such a perspective can become incorporated into the wider consumer culture theory (CCT) framework. Data was collected through a combination of interviews, participant observation of live events, and observation of Irish fan forums. The positioning of the researcher as an âoutsiderparticipantâ represents a departure from previous âmetalâ studies and increasingly common âinsiderâ accounts of youth cultures. Additionally, the adoption of the Eliasian position concerning the balance between involvement and detachment addresses some of the challenges that come with researching (sub)cultures that are as controversial and divisive (in an aesthetical sense) as heavy metal. The seemingly chaotic and âuncivilisedâ associations with heavy metal subculture represent an interesting context in which to explore Eliasian concepts concerning civilising processes and the increasing social constraint towards selfrestraint or self-steering. I draw from empirical data collected in the field and previous figurational histories concerning Irish civilising processes (Dolan, 2005), sportisation (Elias and Dunning, 2008a) and technisation trends (Elias, 2008a). In doing so, I explain how heavy metal is a figuration based on control. The different fan spaces are co-constructed through a combination of subcultural and marketplace controls. Such spaces are used to facilitate a sense of comradeship and generate cathartic experiences, as the fans engage in a âcontrolled de-controllingâ of emotions (Elias, 2008b). The significance of the heavy metal experience is dependent on the visibility and quality of marketplace influence and the successful enforcement of the subcultural fan code. The dynamics of the complex figuration of heavy metal, the unique modes of behaviour, and the communication and interpretation of different symbols within the scene are analysed with regard to how status and subcultural capital is displayed. Fundamentally, I argue that the ability of the fans to adapt their behaviour to the fluid heavy metal scene and its evolving subcultural code is dependent on their ability to selfsteer. The analysis contemplates the breakdown of the subcultural code, the lack of restraint demonstrated in the online spaces, and the retreat of what have become unacceptable modes of behaviour to âbehind the scenesâ and the virtual social scene
Why âethicalâ music festivals may put off revellers
First paragraph: Those who travel to Glastonbury this weekend will have forked out £228 (plus a £5 booking fee) per ticket for the privilege, and many will spend just as much once there. Many music festivals today tend to be associated with such significant sums.

Psychological ownership and music streaming consumption
Streaming is becoming the most common format from which people access, share and listen to music and it is suggested that such practices are indicative of a shift towards a ‘post-ownership’ economy. In the case of music, consumers may place greater value (emotional and monetary) on the physical product because of the lack of legal ownership and/or absence of perceived ownership associated with streaming. This article examines how experiences of ownership are articulated through music streaming formats via qualitative interviews and an online themed discussion group. Drawing from psychological ownership theory we identify motivations (place, identity and control), antecedents (investing the self, coming to intimately know the target, pride and controlling the target) and outcomes (loyalty, empowerment and social rewards) of psychological ownership that are evident in the consumers' experiences of music streaming. This has theoretical and managerial implications for our understanding of how consumers engage with the post-ownership economy
Sport fandom and parenthood
Research question: Sport fandom is acknowledged as offering consumers the opportunity to differentially engage as well as co-create value through network interaction, enhancing social well-being and social integration. However, recent research indicates that sport fandom escalates or de-escalates over time with calls to examine the intersection of parenting and sport fandom. This research focuses on mothers and fathers and examines how their sport fandom intensifies or declines as a consequence of having and raising children. This research will add to our understanding of fandom by identifying when and under what circumstances sport fandom is a bonding or detaching experience for parents and the role it plays in socialization and consumer behavior. Research methods: The study adopts a multi-method interpretive qualitative approach, using in-depth interviews and an online discussion forum. The sampling frame consists of a total of thirty five parents using two stages of research (Stage 1 n=15, Stage 2 n=20). Participants are at varying stages of parenthood with single and mixed gender families. Results and Findings: The study develops a typology of (de)escalating sport fandom during parenthood and differentiates between fandom as pertaining to an individual or social identity. Data also reveals varying dichotomies such as: excess and moderation, risk and reward, individual and shared behaviors (including customer-to-customer interaction) as well as perceptions of allegiance and disloyalty. Implications: Knowledge of parenting and sport fandom will assist managers in developing effective loyalty schemes and marketing packages and will offer an understanding of the temporal effect of having children on fandom
