Baryons, Skyrmions and -periodicity anomaly in chiral and vector-like gauge theories
Stefano Bolognesi, Andrea Luzio, Giacomo Santoni
In this paper, we study the baryons and solitons of chiral and vector-like gauge theories with matter in mixed one and two-index representations. Focusing on the Color-flav…
Moduli spaces and breather dynamics of analytic solutions in Heisenberg exchange-free chiral magnets
Bruno Barton-Singer, Stefano Bolognesi, Sven Bjarke Gudnason +1
We investigate the special case of the chiral magnet with vanishing Heisenberg exchange energy, whose axisymmetric Skyrmion solution has previously been found. The dynamical equati…
Solitonic vortices and black holes with vortex hair in AdS
Roberto Auzzi, Stefano Bolognesi, Giuseppe Nardelli +2
We study soliton and black hole solutions with scalar hair in AdS in a theory with a Maxwell field and a charged scalar field with double trace boundary conditions, which can t…
Higher-dimensional magnetic Skyrmions
Sven Bjarke Gudnason, Stefano Bolognesi, Roberto Menta
We propose a generalization of the theory of magnetic Skyrmions in chiral magnets in two dimensions to a higher-dimensional theory with magnetic Skyrmions in three dimensions and a…
Chiral gauge theories, generalized anomalies and breakdown of the color-flavor-locked center symmetry
Stefano Bolognesi, Kenichi Konishi, Andrea Luzio +1
We study the strong-interaction dynamics of a class of chiral gauge theories with a fermion in a symmetric second-rank tensor representation and a number of fermions i…
Magnetic Skyrmions: from lumps to supercompactons
Stefano Bolognesi, Sven Bjarke Gudnason, Roberto Menta
The magnetic Skyrmion is described by one control parameter and one length scale. We study the two extreme limits of the control parameter - infinitely large and vanishing - and fi…
