Chirality transfer and chiral turbulence in gauge theories
نویسندگان
چکیده
Chirality transfer between fermions and gauge fields plays a crucial role for understanding the dynamics of anomalous transport phenomena such as Chiral Magnetic Effect. In this proceeding we present first principles study these processes based on classical-statistical real-time lattice simulations strongly coupled QED $(e^2N_f=64)$. Our demonstrate that chirality imbalance in fermion sector triggers chiral plasma instabilities field sector, which ultimately lead to generation long range helical magnetic via self-similar turbulent cascade helicity.

Chiral gauge theories revisited
A characteristic feature of the electroweak interactions is that the leftand righthanded components of the fermion fields do not couple to the gauge fields in the same way. The term chiral gauge theory is reserved for field theories of this type, while all other gauge theories (such as QCD) are referred to as vector-like, since the gauge fields only couple to vector currents in this case. At fi...
متن کاملLattice Chiral Gauge Theories
I review the substantial progress which has been made recently with the non-perturbative construction of chiral gauge theories on the lattice. In particular, I discuss three different approaches: a gauge invariant method using fermions which satisfy the Ginsparg–Wilson relation, and two gauge non-invariant methods, one using different cutoffs for the fermions and the gauge fields, and one using...
متن کاملLattice Chiral Gauge Theories through Gauge Fixing
After an introduction in which we review the fundamental difficulty in constructing lattice chiral gauge theories, we discuss the analytic and numerical evidence that abelian lattice chiral gauge theories can be non-perturbatively constructed through the gauge-fixing approach. While a complete non-abelian extension is still under construction, we also show how fermion-number violating processes...
متن کاملRegularization of Chiral Gauge Theories
We propose a nonperturbative formulation of chiral gauge theories. The method involves a ‘pre-regulation’ of the gauge fields, which may be implemented on a lattice, followed by a computation of the chiral fermion determinant in the form of a functional integral which is regularized in the continuum. Our result for the chiral determinant is expressed in terms of the vector-like Dirac operator a...
