Lepton and quark masses and mixing in a SUSY model with Δ(384) and CP

open access: yesNuclear Physics B, 2020
We construct a supersymmetric model for leptons and quarks with the flavor symmetry Δ(384) and CP. The peculiar features of lepton and quark mixing are accomplished by the stepwise breaking of the flavor and CP symmetry. The correct description of lepton

Symmetry, Symmetry Breaking and Topology [PDF]

open access: yesSymmetry, 2010
The ground state of a system with symmetry can be described by a group G. This symmetry group G can be discrete or continuous. Thus for a crystal G is a finite group while for the vacuum state of a grand unified theory G is a continuous Lie group. The ground state symmetry described by G can change spontaneously from G to one of its subgroups H as the ...

Symmetry-Breaking Motility [PDF]

open access: yesPhysical Review Letters, 2005
Locomotion of bacteria by actin polymerization, and in vitro motion of spherical beads coated with a protein catalyzing polymerization, are examples of active motility. Starting from a simple model of forces locally normal to the surface of a bead, we construct a phenomenological equation for its motion.

Probing the two-scale-factor universality hypothesis by exact rotation symmetry-breaking mechanism

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We probe the two-scale-factor universality hypothesis by evaluating, firstly explicitly and analytically at the one-loop order, the loop quantum corrections to the amplitude ratios for O(N) $$\lambda \phi ^{4}$$ λ ϕ 4 scalar field theories with rotation ...

Symmetry Breaking in Tournaments [PDF]

open access: yesElectronic Notes in Discrete Mathematics, 2011
We provide upper bounds for the determining number and the metric dimension of tournaments. A set of vertices $S \subseteq V(T)$ is a determining set for a tournament $T$ if every nontrivial automorphism of $T$ moves at least one vertex of $S$, while $S$ is a resolving set for $T$ if every two distinct vertices in $T$ have different distances to some ...

Symmetry-Breaking-Induced Frequency Combs in Graphene Resonators

open access: yes, 2022
Nonlinearities are inherent to the dynamics of two-dimensional materials. Phenomena-like intermodal coupling already arise at amplitudes of only a few nanometers, and a range of unexplored effects still awaits to be harnessed.

Spontaneous Symmetry Breaking in Quantum Systems: Emergence or Reduction? [PDF]

open access: yes, 2013
Beginning with Anderson (1972), spontaneous symmetry breaking (SSB) in infinite quantum systems is often put forward as an example of (asymptotic) emergence in physics, since in theory no finite system should display it. Even the correspondence between

Gauged Peccei-Quinn symmetry — A case of simultaneous breaking of SUSY and PQ symmetry

open access: yesJournal of High Energy Physics, 2018
Recently, a simple prescription to embed the global Peccei-Quinn (PQ) symmetry into a gauged U(1) symmetry has been proposed. There, explicit breaking of the global PQ symmetry expected in quantum gravity are highly suppressed due to the gauged PQ ...

Probing the electroweak symmetry breaking history with gravitational waves

open access: yesJournal of High Energy Physics, 2023
We perform three dimensional lattice simulation of the electroweak symmetry breaking process through two-step vacuum-like phase transitions with one step being first-order. Our results show that: 1) when the electroweak symmetry breaking is driven by the

Gauge Symmetry Breaking in Gauge Theories---In Search of Clarification [PDF]

open access: yes, 2011
The paper investigates the spontaneous breaking of gauge symmetries in gauge theories from a philosophical angle. Local gauge symmetry itself cannot break spontaneously in quantized gauge theories according to Elitzur's theorem---even though the notion ...
