Anomaly inflow, accidental symmetry, and spontaneous symmetry breaking by Ibrahima Bah, Federico Bonetti

“…By tracking the M-theory origin of the global symmetries of the 4d CFTs, we detect the emergence of an accidental symmetry and the spontaneous symmetry breaking of a U(1) generator. These effects are visible from geometric considerations and not apparent from the point of view of the compactification of the 6d field theory. …”

Symmetry breaking via internal geometry by Andrew Talmadge

“…Gauge theories commonly employ complex vector-valued fields to reduce symmetry groups through the Higgs mechanism of spontaneous symmetry breaking. The geometry of the internal space V is tacitly assumed to be the metric geometry of some static, nondynamical hermitian metric k. …”

A cosmological reconstruction of the Higgs vacuum expectation value by Soumya Chakrabarti, V. Anagha, Selva Ganesh, Vivek Menon

“…The scalar self-interaction is Higgs-like and provokes a spontaneous symmetry breaking. The coefficient of the quadratic term in the self-interaction potential has an evolution and it leads to a cosmic variation of proton-to-electron mass ratio, $$\mu $$ μ . …”

Origins and conservation of topological polarization defects in resonant photonic-crystal diffraction by Yin Xuefan, Inoue Takuya, Peng Chao, Noda Susumu

“…These polarization defects eventually originate from the spontaneous symmetry breaking of line degeneracies fixed at Brillouin zone center or edges, or inter-band coupling caused by accidental Bloch band crossings. …”

Vacuum energy density from the form factor bootstrap by André LeClair

“…If we assume the observed Cosmological Constant originates from the vacuum energy density ρ vac computed as proposed here, then this suggests there must exist a particle which does not obtain its mass from spontaneous symmetry breaking in the electro-weak sector, which we designate as the “zeron”. …”

A new-old approach to composite scalars with chiral fermion constituents by Christopher T. Hill

“…For super-critical coupling, g02>g0c2, we have μ2<0 leading to spontaneous symmetry breaking. The binding of chiral fermions is semiclassical, not loop-level as in NJL. …”

Left-Right model with radiative double seesaw mechanism by Paulo Areyuna C., A. E. Cárcamo Hernández, Vishnudath K. N., Sergey Kovalenko, Roman Pasechnik, Iván Schmidt

“…Abstract We propose an extended Left-Right symmetric model with an additional global U(1) X symmetry, which collapses to a residual subgroup ℤ 2 after spontaneous symmetry breaking. In this model, the light active neutrino masses are generated via a double seesaw mechanism with the Dirac submatrix arising at one loop. …”

Extracting the symmetries of nonequilibrium quantum many-body systems by Aleksandr N. Mikheev, Viktoria Noel, Ido Siovitz, Helmut Strobel, Markus K. Oberthaler, Jürgen Berges

“…We also use the approach to define and identify spontaneous symmetry breaking far from equilibrium, which is of great relevance for applications to nonequilibrium phase transitions. …”

Spontaneous Lorentz symmetry-breaking constraints in Kalb–Ramond gravity by Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo, Manuel E. Rodrigues, Diego Rubiera-Garcia, Luís F. Dias da Silva, Henrique A. Vieira

“…The ratio of precession frequencies for General Relativity (GR) and KR gravity is computed, with Event Horizon Telescope (EHT) results providing a parameter range for the spontaneous symmetry-breaking of $$-0.185022 \le l \le 0.060938$$ - 0.185022 ≤ l ≤ 0.060938 . …”
