    Using a sub-millimeter exciton-polariton waveguide suitable for integrated photonics, we experimentally demonstrate nonlinear modulation of pico-Joule pulses at the same time as amplification sufficient to compensate the system losses. By comparison ...

    The ground state of the diatomic molecules in nature is inevitably bonding, and its first excited state is antibonding. We demonstrate theoretically that, for a pair of distant adatoms placed buried in three-dimensional-Dirac semimetals, this natural ...

    Chiral magnets are an emerging class of topological matter harboring localized and topologically protected vortex-like magnetic textures called skyrmions, which are currently under intense scrutiny as an entity for information storage and processing. ...

    Point-to-point ray tracing is an important problem in many fields of science. While direct variational methods where some trajectory is transformed to an optimal one are routinely used in calculations of pathways of seismic waves, chemical reactions, ...
  • Bjarnason, Ingi Þorleifur; Menke, William (Society of Exploration Geophysicists, 1993-07)
    Cross-borehole tomography suffers from a well-known problem of data incompleteness: the limited ray coverage dictated by the poor experimental geometry implies that certain features of the velocity field are not determined by the data. Construction of ...

    VALUMICS is a Horizon 2020 project funded by the European Commission (2017-2021). The project structure is highly integrated and transdisciplinary, building on the expertise of over 30 specialists in various fields of research including knowledge ...
  • Cook, David; Davíðsdóttir, Brynhildur (Elsevier, 2021-06)
    Recognising the well-known limitations of economic growth as a litmus test of progress and the call by Target 19 of Sustainable Development Goal (SDG) 17 to “develop measurements on progress on sustainable development that complement gross domestic ...
  • Barry, Tom (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-01-28)
    The geo-political importance of the Arctic is growing while at the same time the onset of climate change has resulted in increasing environmental and social pressures both on Arctic states and the governance architecture through which Arctic issues ...

    Consolidating usability problems (UPs) from problem lists from several users can be a cognitively demanding task for evaluators. It has been suggested that collaboration between evaluators can help this process. In an attempt to learn how evaluators ...
