Spontaneous Twin Symmetry Breaking [PDF]
Physical Review D, 2019 We consider a twin Higgs scenario where the $Z_2$ twin symmetry is broken spontaneously, not explicitly. This scenario provides an interesting interpretation of the Higgs metastability in the standard model; the $SU(4)$ breaking scale $f$ is determined ...

Spontaneous Symmetry Breaking and Chiral Symmetry [PDF]
AIP Conference Proceedings, 2000 In this introductory lecture, some basic features of the spontaneous symmetry breaking are discussed. More specifically, $\sigma $-model, non-linear realization, and some examples of spontaneous symmetry breaking in the non-relativistic system are ...

An introduction to spontaneous symmetry breaking [PDF]
SciPost 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.

Spontaneous Symmetry Breaking and Decoherence in Superconductors [PDF]
Physical Review B, 2007 We show that superconductors have a thin spectrum associated with spontaneous symmetry breaking similar to that of antiferromagnets, while still being in full agreement with Elitzur's theorem, which forbids the spontaneous breaking of local (gauge ...

Spontaneous symmetry breaking and gravity [PDF]
Physical Review D, 2011 Gravity is usually considered to be irrelevant as far as the physics of elementary particles is concerned and, in particular, in the context of the spontaneous symmetry breaking (SSB) mechanism. We describe a version of the SSB mechanism in which gravity

Spontaneous symmetry breaking in tensor theories [PDF]
Journal of High Energy Physics, 2019 In this work we study spontaneous symmetry breaking patterns in tensor models. We focus on the patterns which lead to effective matrix theories transforming in the adjoint of U(N).

Anomaly inflow, accidental symmetry, and spontaneous symmetry breaking [PDF]
Journal of High Energy Physics, 2020 We consider the 6d (1,0) SCFT on a stack of N M5-branes probing a ℂ2/ℤ2 singularity. In particular, we study its compactifications to four dimensions on a smooth genus-g Riemann surface with non-trivial flavor flux, yielding a family of 4d CFTs.

Decoherence induced spontaneous symmetry breaking [PDF]
Optics Communications, 2009 We study time dependence of exchange symmetry properties of Bell states when two qubits interact with local baths having identical parameters. In case of classical noise, we consider a decoherence Hamiltonian which is invariant under swapping the first ...

Spontaneous Symmetry Breaking through Mixing [PDF]
Europhysics Letters (EPL), 2006 We discuss a model, in which the negative mass square needed in the Higgs mechanism is generated by mixing with a heavy scalar. We have two scalar doublets in the standard model. Phenomenological properties of the heavy new scalar are discussed.

Spontaneous symmetry breaking on surface defects
Journal of High Energy PhysicsColeman’s theorem states that continuous internal symmetries cannot be spontaneously broken in two-dimensional quantum field theories (QFTs). In this work we consider surface (i.e. two-dimensional) defects in d-dimensional conformal field theories (CFTs)
