    On some operators with spectral density increasing as exp [ Const. E*E ]

    Abstract:
    Motivated by a putative model of black holes as quantum objects we consider what types of operators would have a corresponding spectrum. We find that there are indeed such operators, but of a rather unusual types, and for which the wave functions are only barely localized. We point out a tension between such almost delocalized states and black holes as compact objects.

    Inside Nature Physics

    Abstract:
    What happens to your paper after you submit it to a journal is not always clear from the outside, but it’s helpful for authors to understand the editorial process so that they can navigate it smoothly. In this talk, we will unpack this process and explain how editors make their decisions. We will introduce Nature Physics (and other journals in the Nature Portfolio) and describe how we see our role in the scientific community and what we are trying to achieve. Building on that, we will discuss how we select papers for peer review based on the likely breadth of interest in the results that they contain, and how we interpret the information in peer review reports in terms of technical and editorial concerns. We'll also leave plenty of time for questions and discussion.

    Den kosmiska skattjakten: Hur tillverkar universum grundämnen som guld?

    Sammanfattning:
    Allt omkring oss, och även vår kropp, är uppbyggt av grundämnen. Men har du någonsin undrat var dessa element kommer ifrån? Om du har det, då är den här föreläsningen rätt plats. Här kommer vi att gå på en resa till kosmos för att upptäcka grundämnenas ursprung. Vi kommer att ta reda på varifrån grundämnen som syre som vi andas in kommer ifrån och kommer även att ge oss ut på en "kosmisk skattjakt" efter guld som vi använder i våra smycken. Så följ med oss och ta reda på mer om hur kosmos skapade alla grundämnena runt omkring oss!
