Chiral and deconfinement transitions in a magnetic background using the functional renormalization group with the Polyakov loop
(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 ... -
Cold Baryogenesis from first principles in the two-Higgs doublet model with fermions
(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 ... -
Dimensional reduction of the Standard Model coupled to a new singlet scalar field
(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 ... -
Effective field theory and electroweak baryogenesis in the singlet-extended Standard Model
(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 ... -
Inverse magnetic catalysis and regularization in the quark-meson model
(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 ... -
Killing superalgebras for Lorentzian four-manifolds
(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
(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 ...
