Lepton flavor violation and collider searches in a type I + II seesaw model by Manoel M. Ferreira, Tessio B. de Melo, Sergey Kovalenko, Paulo R. D. Pinheiro, Farinaldo S. Queiroz

“…In this work, we discuss a model where a type I + II seesaw mechanism naturally arises via spontaneous symmetry breaking of an enlarged gauge group. Lepton flavor violation is a common feature in such setup and for this reason, we compute the model contribution to the $$\mu \rightarrow e\gamma $$ μ→eγ and $$\mu \rightarrow 3e$$ μ→3e decays. …”

Optical Pattern Formation in a Rydberg-Dressed Atomic Gas with Non-Hermitian Potentials by Zeyun Shi, Lu Qin, Xingdong Zhao, Haibo Huang

“…We find that through the nonlocal Kerr nonlinearity contributed by the long-range atom–atom interaction, a constant-intensity wave (CIW) may undergo modulation instability and induce spontaneous symmetry breaking, resulting in the emergence of various self-organized optical structures, which can be actively manipulated by tuning the nonlocality degree of the Kerr nonlinearity and by designing the non-Hermitian optical potentials. …”

Mingling of the infrared and ultraviolet and the “cosmological constant” for interacting QFT in 2d by André LeClair

“…For massless cases, m can be a scale of spontaneous symmetry breaking. The “cosmological constant problem” generically arises in the free field limit g $$ \mathfrak{g} $$ → 0, thus interactions can potentially resolve the problem at least for most cases considered in this paper. …”

Constraining dark matter from strong phase transitions in a U 1 L μ − L τ $$ \textrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ model: implications for neutrino masses and muon g − 2 by Sandhya Choubey, Sarif Khan, Marco Merchand, Sampsa Vihonen

“…The model offers an easy resolution to the muon (g – 2) anomaly, which fixes the scale of spontaneous symmetry breaking. Furthermore, the two-zero minor structure in the RHN mass matrix provides successful predictions for neutrino oscillation parameters, including the Dirac phase. …”

Self-induced Berry flux and spontaneous non-equilibrium magnetism by Rudner, Mark S., Song, Justin Chien Wen

Avoided quasiparticle decay and enhanced excitation continuum in the spin-1/2 near-Heisenberg triangular antiferromagnet Ba3CoSb2O9 by Macdougal, D, Williams, S, Prabhakaran, D, Bewley, RI, Voneshen, DJ, Coldea, R

“…Finally, through measurements in a strong applied magnetic field, we find evidence for magnetic domains with opposite senses for the spin rotation in the 120 degree ordered ground state, as expected in the absence of Dzyaloshinskii-Moriya interactions, when the sense of spin rotation is selected via spontaneous symmetry breaking.…”

Self‐Solidifying Active Droplets Showing Memory‐Induced Chirality by Kai Feng, José Carlos Ureña Marcos, Aritra K. Mukhopadhyay, Ran Niu, Qiang Zhao, Jinping Qu, Benno Liebchen

“…An aqueous solution of surface tension–lowering polyelectrolytes self‐solidifies on the surface of acidic water, during which polyelectrolytes are gradually emitted into the surrounding water and induce linear self‐propulsion via spontaneous symmetry breaking. The low diffusion coefficient of the polyelectrolytes leads to long‐lived chemical trails which cause memory effects that drive a transition from linear to chiral motion without requiring any imposed symmetry breaking. …”

N $$ \mathcal{N} $$ = 4 SYM, Argyres-Douglas theories, and an exact graded vector space isomorphism by Matthew Buican, Takahiro Nishinaka

“…We begin by observing that the Schur indices of these two theories are related by an algebraic transformation that is surprisingly reminiscent of index transformations describing spontaneous symmetry breaking on the Higgs branch. However, this transformation breaks half the supersymmetry of the SYM theory as well as its full N $$ \mathcal{N} $$ = 2 SU(2) F flavor symmetry. …”
