    Conductivities from attractors 
    Erdmenger, Johanna; Fernández, Daniel; Goulart, Prieslei; Witkowski, Piotr (Springer Nature, 2017-03)
    In the context of applications of the AdS/CFT correspondence to condensed matter physics, we compute conductivities for field theory duals of dyonic planar black holes in 3+1-dimensional Einstein-Maxwell-dilaton theories at zero temperature. We ...

    Correlation functions in theories with Lifshitz scaling 
    Keränen, Ville; Sybesma, Watse; Szepietowski, Phillip; Thorlacius, Larus (Springer Nature, 2017-05)
    The 2+1 dimensional quantum Lifshitz model can be generalised to a class of higher dimensional free field theories that exhibit Lifshitz scaling. When the dynamical critical exponent equals the number of spatial dimensions, equal time correlation ...

    Decay of muons generated by laser-induced processes in ultra-dense hydrogen H(0) 
    Holmlid, Leif; Olafsson, Sveinn (Elsevier BV, 2019-06)
    This work reports identification of muons by their characteristic life-time of 2.20 μs after laser-induction of their precursor mesons, both kaons K± and KL 0 and pions π± in ultra-dense hydrogen H(0). The pair-production signal from scattered muons ...

    In-gap corner states in core-shell polygonal quantum rings 
    Sitek, Anna; Ţolea, Mugurel; Niţă, Marian; Serra, Llorenç; Gudmundsson, Vidar; Manolescu, Andrei (Springer Nature, 2017-01-10)
    We study Coulomb interacting electrons confined in polygonal quantum rings. We focus on the interplay of localization at the polygon corners and Coulomb repulsion. Remarkably, the Coulomb repulsion allows the formation of in-gap states, i.e., ...
