Dilatons for Dense Hadronic Matter

open access: yes, 2009
The idea that the explicit breaking of scale invariance by the trace anomaly of QCD can be rephrased as a spontaneous breaking has been recently exploited to capture the low-energy strong interaction dynamics of dense (and also hot) matter in terms of ...

Non-Hermitian non-Abelian topological insulators with PT symmetry

open access: yesPhysical Review Research, 2021
We study a non-Hermitian non-Abelian topological insulator preserving PT symmetry, where the non-Hermitian term represents nonreciprocal hoppings. As it increases, a spontaneous PT symmetry breaking transition occurs in the perfect-flat band model from a

Linear stability analysis of chemical mechanism, Listanalchem: A tool for the search of spontaneous mirror symmetry breaking

open access: yesMethodsX, 2023
Homochirality, the phenomenon by which one of two virtually identical (non-superimposable mirror images) compounds is favored over the other in the chemistry of life, has been regarded as a requisite for the emergence of all living things on earth ...

Supersymmetry Breaking, R-Symmetry Breaking and Metastable Vacua

open access: yes, 2007
Models of spontaneous supersymmetry breaking generically have an R-symmetry, which is problematic for obtaining gaugino masses and avoiding light R-axions.

Mach's Principle and Model for a Broken Symmetric Theory of Gravity [PDF]

open access: yes, 2002
We investigate spontaneous symmetry breaking in a conformally invariant gravitational model. In particular, we use a conformally invariant scalar tensor theory as the vacuum sector of a gravitational model to examine the idea that gravitational coupling ...

An introduction to spontaneous symmetry breaking

open access: yesSciPost Physics Lecture Notes, 2019
Perhaps the most important aspect of symmetry in physics is the idea that a state does not need to have the same symmetries as the theory that describes it. This phenomenon is known as spontaneous symmetry breaking.

R-symmetry and Supersymmetry Breaking at Finite Temperature [PDF]

open access: yes, 2009
We analyze the spontaneous $U(1)_R$ symmetry breaking at finite temperature for the simple O'Raifeartaigh-type model introduced in [1] in connection with spontaneous supersymmetry breaking.

Spontaneous breaking of non-relativistic scale symmetry

open access: yesJournal of High Energy Physics, 2017
We analyze the mechanism of spontaneous symmetry breaking of scale invariance in Galilean invariant field theories. We show that the existence of a dynamic gapless dilaton mode depends on whether the U(1) particle number or the Galilean boost symmetry ...

Spontaneous symmetry breaking of coupled Fabry–Pérot nanocavities

open access: yesCommunications Physics
Ring cavities are quickly emerging as preferential platforms to investigate spontaneous symmetry breaking. However, research on handedness polarisation splitting within Kerr-coupled cavities is yet at a preliminary stage.
