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

, 2003
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 ...

Spontaneous breaking of non-relativistic scale symmetry

Journal 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 ...

Patterns of Spontaneous Chiral Symmetry Breaking in Vectorlike Gauge Theories [PDF]

, 2001
It has been conjectured that spontaneous chiral symmetry breaking in strongly coupled vectorlike gauge theories falls into only three different classes, depending on the gauge group and the representations carried by the fermions.

Spontaneous symmetry breaking from anyon condensation

Journal of High Energy Physics, 2019
In a physical system undergoing a continuous quantum phase transition, spontaneous symmetry breaking occurs when certain symmetries of the Hamiltonian fail to be preserved in the ground state.

Time crystal behavior of excited eigenstates

, 2017
In analogy to spontaneous breaking of continuous space translation symmetry in the process of space crystal formation, it was proposed that spontaneous breaking of continuous time translation symmetry could lead to time crystal formation. In other words,

Spontaneous symmetry breaking in quantum mechanics [PDF]

American Journal of Physics, 2007
We present a mathematically simple procedure to explain spontaneous symmetry breaking in quantum systems. The procedure is applicable to a wide range of models and can be easily used to explain the existence of a symmetry broken state in crystals, antiferromagnets, and even superconductors.

Holographic entanglement density for spontaneous symmetry breaking

Journal of High Energy Physics, 2022
We investigate the properties of the holographic entanglement entropy of the systems in which the U(1) or the translational symmetry is broken spontaneously.

Spontaneous scale symmetry breaking at high temperature

Journal of High Energy Physics, 2023
We consider a scale symmetric extension of the Standard Model Higgs scalar sector. The new sector, dilaton, is responsible for the generation of mass scales and may have geometric origin in the Weyl gravity R ~ 2 $$ {\overset{\sim }{R}}^2 $$ term.

Supersymmetry Breaking, R-Symmetry Breaking and Metastable Vacua

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