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.

Holographic entanglement density for spontaneous symmetry breaking [PDF]
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 symmetry breaking on surface defects [PDF]
Journal of High Energy Physics, 2023 Coleman’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)

Diagnosing strong-to-weak symmetry breaking via Wightman correlators
Communications PhysicsSymmetry plays a fundamental role in quantum many-body physics, and a central concept is spontaneous symmetry breaking. Recent developments highlight new symmetry-breaking patterns known as strong-to-weak spontaneous symmetry breaking, characterized by ...

Spontaneous symmetry breaking from anyon condensation [PDF]
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.

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).

The spontaneous symmetry breaking in Ta2NiSe5 is structural in nature. [PDF]
Proc Natl Acad Sci U S A, 2023 Significance In the quest for collective phases of matter that can lead to novel quantum properties, a long-sought example is the excitonic insulator—an exotic state where excitons spontaneously form in thermodynamic equilibrium and undergo Bose–Einstein

Spontaneous time-reversal symmetry breaking in twisted double bilayer graphene [PDF]
Nature Communications, 2022 Twisted double bilayer graphene (tDBG) comprises two Bernal-stacked bilayer graphene sheets with a twist between them. Gate voltages applied to top and back gates of a tDBG device tune both the flatness and topology of the electronic bands, enabling an ...
