    • 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 ...
    • 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 ...

      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, ...
    • Primordial Gravitational Waves with LISA 

      Ricciardone, Angelo (Journal article; Peer reviewed, 2017)
      Primordial Gravitational Waves are the next target of modern cosmology. They represent a window on the early Universe and the only probe of the physics and microphysics of the inflationary period. When the production of ...

      Eukaryotic protein phosphatase 4 (PP4) is a PP2A-type protein phosphatase that is part of a conserved complex with regulatory factors PSY2 and PP4R2. Various lines of Arabidopsis thaliana with mutated PP4 subunit genes ...
    • Effective field theory and electroweak baryogenesis in the singlet-extended Standard Model 

      Damgaard, P.H.; Haarr, A.; O'Connell, D.; Tranberg, Anders (Journal article; Peer reviewed, 2016-02)
      Electroweak baryogenesis is a simple and attractive candidate mechanism for generating the observed baryon asymmetry in the Universe. Its viability is sometimes investigated in terms of an effective field theory of the ...
    • Killing superalgebras for Lorentzian four-manifolds 

      de Medeiros, Paul; Figueroa-O’Farrill, José; Santi, Andrea (Journal article; Peer reviewed, 2016-06)
      We determine the Killing superalgebras underpinning field theories with rigid unextended supersymmetry on Lorentzian four-manifolds by re-interpreting them as filtered deformations of Z-graded subalgebras with maximum odd ...
    • Submaximal conformal symmetry superalgebras for Lorentzian manifolds of low dimension 

      de Medeiros, Paul (Journal article; Peer reviewed, 2016-02)
      We consider a class of smooth oriented Lorentzian manifolds in dimensions three and four which admit a nowhere vanishing conformal Killing vector and a closed two-form that is invariant under the Lie algebra of conformal ...
    • Cold Baryogenesis from first principles in the two-Higgs doublet model with fermions 

      Mou, Zong-Gang; Saffin, Paul M.; Tranberg, Anders (Journal article; Peer reviewed, 2015-06)
      We present a first-principles numerical computation of the baryon asymmetry in electroweak-scale baryogenesis. For the scenario of Cold Baryogenesis, we consider a one fermion-family reduced CP-violating two Higgs-doublet ...
    • Chiral and deconfinement transitions in a magnetic background using the functional renormalization group with the Polyakov loop 

      Andersen, Jens O.; Naylor, William R.; Tranberg, Anders (Journal article; Peer reviewed, 2014-04)
      We use the Polyakov loop coupled quark-meson model to approximate low energy QCD and present results for the chiral and deconfinement transitions in the presence of a constant magnetic background B at finite temperature T ...

      Mork-Jansson, Astrid; Bue, Ann Kristin; Gargano, Daniela; Furnes, Clemens; Reisinger, Veronika; Arnold, Janine; Kmiec, Karol; Eichacker, Lutz Andreas (Journal article; Peer reviewed, 2015-06)
      The light-harvesting-like (LIL) proteins are a family of membrane proteins that share a chlorophyll a/b-binding motif with the major light-harvesting antenna proteins of oxygenic photoautotrophs. LIL proteins have been ...
    • Inverse magnetic catalysis and regularization in the quark-meson model 

      Andersen, Jens O.; Naylor, William R.; Tranberg, Anders (Journal article; Peer reviewed, 2015-02)
      Motivated by recent work on inverse magnetic catalysis at finite temperature, we study the quark-meson model using both dimensional regularization and a sharp cutoff. We calculate the critical temperature for the chiral ...
