• Anomaly-Induced Inhomogeneous Phase in Quark Matter without the Sign Problem 

      Brauner, Tomas; Filios, Georgios; Kolesova, Helena (Peer reviewed; Journal article, 2019)
      We demonstrate the existence of an anomaly-induced inhomogeneous phase in a class of vectorlike gauge theories without the sign problem, thus disproving the long-standing conjecture that the absence of the sign problem ...
    • Chiral soliton lattice in QCD-like theories 

      Brauner, Tomas; Filios, Georgios; Kolesova, Helena (Peer reviewed; Journal article, 2019)
      Recently, it has been shown that the ground state of quantum chromodynamics (QCD) in suffciently strong magnetic fields and at moderate baryon number chemical potential carries a crystalline condensate of neutral pions: ...
    • Gauged Wess-Zumino terms for a general coset space 

      Brauner, Tomas; Kolesova, Helena (Peer reviewed; Journal article, 2019)
      The low-energy physics of systems with spontaneously broken continuous symmetry is dominated by the ensuing Nambu-Goldstone bosons. It has been known for half a century how to construct invariant Lagrangian densities for ...
    • Noether currents of locally equivalent symmetries 

      Brauner, Tomas (Peer reviewed; Journal article, 2020)
      Local symmetry transformations play an important role for establishing the existence and form of a conserved (Noether) current in systems with a global continuous symmetry. We explain how this fact leads to the existence ...
