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.

Halogen bond-modulated solid-state reordering and symmetry breaking of azahelicenes [PDF]
Nature CommunicationsSpontaneous symmetry breaking predominately occurs during the aggregation of discrete molecules in solution. Herein, we report a unique solid-state symmetry breaking process of dynamically chiral aza[4]helicenes that emerged in vacuum-driven ...

Ultrafast probing of isotope-induced explicit symmetry breaking in ethylene [PDF]
Communications ChemistrySymmetry governs nature’s laws, yet many of the natural phenomena occur due to the breakdown of symmetry. Here, we show how isotope-induced inversion symmetry breaking influences ultrafast photoisomerization processes in ethylene.

Observation of time-reversal symmetry breaking in the band structure of altermagnetic RuO2 [PDF]
Science Advances, 2023 Altermagnets are an emerging elementary class of collinear magnets. Unlike ferromagnets, their distinct crystal symmetries inhibit magnetization while, unlike antiferromagnets, they promote strong spin polarization in the band structure.

Time-reversal symmetry-breaking charge order in a kagome superconductor [PDF]
Nature, 2021 The kagome lattice1, which is the most prominent structural motif in quantum physics, benefits from inherent non-trivial geometry so that it can host diverse quantum phases, ranging from spin-liquid phases, to topological matter, to intertwined orders2–8

Entanglement asymmetry as a probe of symmetry breaking [PDF]
Nature Communications, 2022 A measure of symmetry breaking in a quantum many-body system could provide insight into its dynamics. Ares et al. introduce a subsystem measure of symmetry breaking dubbed entanglement asymmetry and apply it to quantum quench dynamics in spin chains ...

Continuous symmetry breaking in a two-dimensional Rydberg array [PDF]
Nature, 2022 A two-dimensional dipolar XY model with a continuous spin-rotational symmetry is realized using a programmable Rydberg quantum simulator, complementing recent studies using the Rydberg-blockade mechanism to realize Ising-type interactions showing ...

Superconductivity and Local Inversion-Symmetry Breaking [PDF]
Annual Review of Condensed Matter Physics, 2022 Inversion and time reversal are essential symmetries for the structure of Cooper pairs in superconductors. The loss of one or both leads to modifications to this structure and can change the properties of the superconducting phases in profound ways ...

Neutrino Masses from Generalized Symmetry Breaking [PDF]
Physical Review X, 2022 We explore generalized global symmetries in theories of physics beyond the standard model. Theories of Z′ bosons generically contain “noninvertible” chiral symmetries, whose presence indicates a natural paradigm to break this symmetry by an exponentially
