    Rognes, Knut (Journal article; Peer reviewed, 2016-01)
    A new species, Pollenia bartaki sp. nov., assigned to the Pollenia rudis species-group in Pollenia Robineau-Desvoidy, 1830, is described on the basis of a single male specimen captured in Jordan. Its strongly curved surstylus ...
  • Simulations of "tunnelling of the 3rd kind" 

    Mou, Zonggang; Saffin, Paul M.; Tognarelli, Paul; Tranberg, Anders (Journal article; Peer reviewed, 2017-07)
    We consider the phenomenon of “tunnelling of the 3rd kind” [1], whereby a magnetic field may traverse a classically impenetrable barrier by pair creation of unimpeded quantum fermions. These propagate through the barrier ...
  • Simulations of Cold Electroweak Baryogenesis: hypercharge U(1) and the creation of helical magnetic fields 

    Mou, Zonggang; Saffin, Paul M.; Tranberg, Anders (Journal article; Peer reviewed, 2017-06)
    We perform numerical simulations of Cold Electroweak Baryogenesis, including for the first time in the Bosonic sector the full electroweak gauge group SU(2) × U(1) and CP-violation. We find that the maximum generated baryon ...
  • Dimensional reduction of the Standard Model coupled to a new singlet scalar field 

    Brauner, Tomas; Tenkanen, Tuomas; Tranberg, Anders; Vuorinen, Aleksi; Weir, David James (Journal article; Peer reviewed, 2017)
    We derive an effective dimensionally reduced theory for the Standard Model augmented by a real singlet scalar. We treat the singlet as a superheavy field and integrate it out, leaving an effective theory involving only the ...
  • On high-order perturbative calculations at finite density 

    Ghisoiu, Ioan; Gorda, Tyler; Kurkela, Aleksi; Romatschke, Paul; Säppi, Matias; Vuorinen, Aleksi (Journal article; Peer reviewed, 2017-02)
    We discuss the prospects of performing high-order perturbative calculations in systems characterized by a vanishing temperature but finite density. In particular, we show that the determination of generic Feynman integrals ...
  • Simulations of Cold Electroweak Baryogenesis: finding the optimal quench time 

    Mou, Zonggang; Saffin, Paul M.; Tranberg, Anders (Journal article; Peer reviewed, 2017-07)
    We revisit the numerical computation of the baryon asymmetry from Cold Electroweak Baryogenesis given the physical Higgs mass. We investigate the dependence of the asymmetry on the speed at which electroweak symmetry ...
  • Chiral soliton lattice and charged pion condensation in strong magnetic fields 

    Brauner, Tomas; Yamamoto, Naoki (Journal article; Peer reviewed, 2017-04)
    The Chiral Soliton Lattice (CSL) is a state with a periodic array of topological solitons that spontaneously breaks parity and translational symmetries. Such a state is known to appear in chiral magnets. We show that CSL ...
  • Anomalous electrodynamics of neutral pion matter in strong magnetic fields 

    Brauner, Tomas; Kadam, Saurabh (Journal article; Peer reviewed, 2017-03)
    The ground state of quantum chromodynamics in sufficiently strong external magnetic fields and at moderate baryon chemical potential is a chiral soliton lattice (CSL) of neutral pions [1]. We investigate the interplay ...
  • Inhomogeneous chiral condensate in the quark-meson model 

    Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article; Peer reviewed, 2017-07-24)
  • On-shell parameter fixing in the quark-meson model 

    Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article; Peer reviewed, 2017-02)
    The quark-meson model is often used as an effective low-energy model for QCD to study the chiral transition at finite temperature T and baryon chemical potential μB. The parameters in the quark-meson model can be found by ...
  • Variable setpoint as a relaxing component in physiological control 

    Risvoll, Geir; Thorsen, Kristian; Ruoff, Peter; Drengstig, Tormod (Journal article; Peer reviewed, 2017-09)
    Setpoints in physiology have been a puzzle for decades, and especially the notion of fixed or variable setpoints have received much attention. In this paper, we show how previously presented homeostatic controller motifs, ...
