Four-field symmetry breakings in twin-resonator photonic isomers
Physical Review Research, 2023 Symmetry and symmetry breaking of light states play an important role in photonic integrated circuits and have recently attracted lots of research interest that is relevant to the manipulation of light polarization, telecommunications, all optical ...

Modeling spontaneous breaking of time-translation symmetry
, 2015 We show that an ultra-cold atomic cloud bouncing on an oscillating mirror can reveal spontaneous breaking of a discrete time translation symmetry. In many-body simulations we illustrate the process of the symmetry breaking that can be induced by atomic ...

A hadron model with breaking of spatial homogeneity of vacuum [PDF]
, 2007 A possible breaking of spatial homogeneity of vacuum due to the interaction between quark and Bose-field is analyzed. It is shown that in this case quark can be in a localized state (like wave packet). Energetic conditions for such a spontaneous symmetry

Curling Liquid Crystal Microswimmers: A Cascade of Spontaneous Symmetry Breaking. [PDF]
Physical Review Letters, 2016 We report curling self-propulsion in aqueous emulsions of common mesogenic compounds. Nematic liquid crystal droplets self-propel in a surfactant solution with concentrations above the critical micelle concentration while undergoing micellar ...

Advanced Functional Materials, EarlyView.Persistent secondary phases govern the performance of many thermoelectric materials, particularly of high performance MgAgSb. In this study advanced microstructural characterization for unequivocal phase identification combined with transport modeling and statistical analysis enabled the quantification of each phase's impact, revealing the most ...

Advanced Functional Materials, EarlyView.Uniaxial compressive stress induces spatially heterogeneous AFE–FE phase transitions in polycrystalline NaNbO3, as visualized by Raman mapping. Mechanical loading reduces coercive stress and enhances backswitching, attributed to long‐range ferroelectric ordering and non‐180° domain switching, elucidating the complex stress‐driven structural and ...

Scalar dark matter search from the extended νTHDM
Journal of High Energy Physics, 2018 We consider a neutrino Two Higgs Doublet Model (νTHDM) in which neutrinos obtain naturally small Dirac masses from the soft symmetry breaking of a global U(1) X symmetry.

On-shell constructibility of Born amplitudes in spontaneously broken gauge theories
Journal of High Energy Physics, 2020 We perform a comprehensive study of on-shell recursion relations for Born amplitudes in spontaneously broken gauge theories and identify the minimal shifts required to construct amplitudes with a given particle content and spin quantum numbers.

Minima of classically scale-invariant potentials
Journal of High Energy Physics, 2021 We propose a new formalism to analyse the extremum structure of scale-invariant effective potentials. The problem is stated in a compact matrix form, used to derive general expressions for the stationary point equation and the mass matrix of a multi ...

Spontaneous versus explicit replica symmetry breaking in the theory of disordered systems
, 2009 We investigate the relation between spontaneous and explicit replica symmetry breaking in the theory of disordered systems. On general ground, we prove the equivalence between the replicon operator associated with the stability of the replica symmetric ...
