Field sources in a Lorentz symmetry breaking scenario with a single background vector [PDF]
, 2014 This paper is devoted to investigating the interactions between stationary sources of the electromagnetic field, in a model which exhibits explicit Lorentz-symmetry breaking due to the presence of a single background vector. We focus on physical phenomena that emerge from this kind of breaking and which have no counterpart in Maxwell Electrodynamics.

LIGHT PSEUDO-GOLDSTONE BOSONS WITHOUT EXPLICIT SYMMETRY BREAKING [PDF]
, 2007 A mechanism is discussed to obtain light scalar fields from a spontaneously broken continuous symmetry without explicitly breaking it. If there is a continuous manifold of classical vacua in orbit space, its tangent directions describe classically ...

A unified description of translational symmetry breaking in holography [PDF]
Journal of High Energy Physics, 2019 We provide a complete and unified description of translational symmetry breaking in a simple holographic model. In particular, we focus on the distinction and the interplay between explicit and spontaneous breaking.

Flavor Symmetry Breaking and Strangeness in the Nucleon [PDF]
, 2002 We suggest that breaking of SU(3) flavor symmetry mainly resides in the baryon wave--functions while the charge operators have no (or only small) explicit symmetry breaking components. We utilize the collective coordinate approach to chiral soliton models to support this picture. In particular we compute the $g_A/g_V$ ratios for hyperon beta--decay and

Fragmentation and quark distribution functions for the pion and kaon with explicit flavor-SU(3)-symmetry breaking [PDF]
, 2012 We investigate the unpolarized pion and kaon fragmentation functions, employing the nonlocal chiral-quark model, which manifests the nonlocal interactions between the quarks and pseudoscalar mesons, considering the explicit flavor-SU(3)-symmetry breaking

Double field domain walls with explicit symmetry breaking
, 2012 We study the dynamics of domain walls in a double-field model in which the U(1) symmetry is broken both spontaneously and explicitly. The global U(1) symmetry of the system is restored when the symmetry breaking parameter $\epsilon$ is set to zero.

Cluster percolation and explicit symmetry breaking in spin models [PDF]
, 2002 Many features of spin models can be interpreted in geometrical terms by means of the properties of well defined clusters of spins. In case of spontaneous symmetry breaking, the phase transition of models like the q-state Potts model, O(n), etc., can be ...

Diagnosis of explicit symmetry breaking in the tight-binding constructions for symmetry-protected topological systems [PDF]
, 2020 It has been well established that for symmetry protected topological systems, the non-trivial topology prevents a real space representation using exponentially localized Wannier wavefunctions (WFs) in all directions, unless the protecting symmetry is ...

Holographic Non-Abelian Flavour Symmetry Breaking [PDF]
Universe, 2023 We investigate a holographic model for both spontaneous and explicit symmetry breaking of non-abelian flavour symmetries. This consists of a bottom-up model inspired by the top-down D3/probe D7-brane model.

Quantum noise as a symmetry-breaking field [PDF]
Physical review B, 2022 We investigate the effect of quantum noise on the measurement-induced quantum phase transition in monitored random quantum circuits. Using the efficient simulability of random Clifford circuits, we find that the transition is broadened into a crossover ...
