Supersymmetry Without Time-Reversal Invariance in Model A: A FRG perspective
Sankarshan Sahu, Bertrand Delamotte, Adam Rançon +1
We show that, contrary to common belief, supersymmetry alone is not sufficient in Model A dynamics to ensure relaxation toward a stationary state satisfying time-reversal invarianc…
Effects of fermions in one-loop propagators in the Curci-Ferrari-Delbourgo-Jarvis gauge
Santiago Cabrera, Marcela Peláez, Matthieu Tissier
We present the one-loop computation of the quark propagator in the Curci-Ferrari-Delbourgo- Jarvis (CFDJ) gauge, extending previous analyses to include dynamical quarks. Using the…
Scenario for quark confinement from infrared safe Yang-Mills dynamics
Marcela Peláez, Urko Reinosa, Julien Serreau +2
We revisit the non-Abelian dipole problem in the context of a simple semiclassical approach that incorporates some essential features of the infrared sector of Yang-Mills theories…
Center-symmetric Landau gauge, the deconfinement transition and the gluon propagator as seen in lattice QCD
Duifje Maria van Egmond, Orlando Oliveira, Urko Reinosa +3
We address the lattice computation of the gluon propagator in the center-symmetric Landau gauge. After discussing a proper lattice implementation of the center-symmetric Landau gau…
On the breakdown of dimensional reduction and supersymmetry in random-field models
Gilles Tarjus, Matthieu Tissier, Ivan Balog
We discuss the breakdown of the Parisi-Sourlas supersymmetry (SUSY) and of the dimensional-reduction (DR) property in the random field Ising and O() models as a function of spac…
The center-symmetric Landau gauge meets the lattice
Duifje Maria van Egmond, Orlando Oliveira, Urko Reinosa +3
A lattice implementation of the recently introduced center-symmetric Landau gauge is discussed and its predictions confronted with numerical Monte Carlo simulations. It is shown th…
