• Exact Solutions of the Field Equations for Empty Space in the Nash Gravitational Theory 

      Aadne, Matthew Terje; Grøn, Øyvind (Journal article; Peer reviewed, 2017-02)
      John Nash has proposed a new theory of gravity. We define a Nash-tensor equal to the curvature tensor appearing in the Nash field equations for empty space, and calculate its components for two cases: 1. A static, spherically ...
    • Quarkonium phenomenology from a generalised Gauss law 

      Lafferty, David; Rothkopf, Alexander Karl (Peer reviewed; Journal article, 2019-05)
      We present an improved analytic parametrisation of the complex in-medium heavy quark potential derived rigorously from the generalised Gauss law. To this end we combine in a self-consistent manner a non-perturbative vacuum ...
    • Quarkonium production in the QGP 

      Rothkopf, Alexander Karl (Peer reviewed; Journal article, 2019-05)
      We report on recent theory progress in understanding the production of heavy quarkonium in heavy-ion collisions based on the in-medium heavy-quark potential extracted from lattice QCD simulations. On the one hand, the ...
    • Transport Properties of Superfluid Phonons in Neutron Stars 

      Manuel, Cristina; Tolos Rigueiro, Laura (Peer reviewed; Journal article, 2021-03)
      We review the effective field theory associated with the superfluid phonons that we use for the study of transport properties in the core of superfluid neutrons stars in their low temperature regime. We then discuss the ...
