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.

Restoration of supersymmetric Slavnov-Taylor and Ward identities in presence of soft and spontaneous symmetry breaking

, 2003
Supersymmetric Slavnov-Taylor and Ward identities are investigated in presence of soft and spontaneous symmetry breaking. We consider an abelian model where soft supersymmetry breaking yields a mass splitting between electron and selectron and triggers ...

Nematicon-enhanced spontaneous symmetry breaking [PDF]

Molecular Crystals and Liquid Crystals, 2017
We investigate topological and optical spontaneous symmetry breaking in nematic liquid crystals subject to the Fréedericksz transition. Specular nematicon states couple to mirrored distributions of the director due to symmetry breaking, with transverse velocities controlled by beam power in the strong nonlinear regime. Hysteresis in transverse velocity

Roulette‐Inspired Physical Unclonable Functions: Stochastic yet Deterministic Multi‐Bit Patterning through the Solutal Marangoni Effect

Advanced Functional Materials, EarlyView.
Geometric multi‐bit patterning based on dynamic wetting and dewetting phenomena creates roulette‐like Physical Unclonable Function (PUF) labels with stochastic yet deterministic properties. This method leverages the solutal‐Marangoni effect for high randomness while achieving deterministic multinary patterns through polygonal confinement of binary ...

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.

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 ...

Enhanced Electromechanical Response in 1D Hybrid Perovskites: Coexistence of Normal and Relaxor Ferroelectric Phases

Advanced Functional Materials, EarlyView.
The dynamic polarization reversal of coexisting normal and relaxor ferroelectrics in 1D TMAPbI₃ (tetramethylammonium, TMA) is deciphered through combined experimental and theoretical approaches. By bridging atomic‐scale motion, macroscopic polarization switching, and depolarization effects, a universal methodology is established to engineer next ...

Low-Lying Excited States of Quantum Antiferromagnets on a Triangular Lattice

, 1994
We study low-lying states of the XY and Heisenberg antiferromagnets on a triangular lattice to clarify whether spontaneous symmetry breaking occurs at $T=0$ in the thermodynamic limit.

Supercompliant Lattice Boosts n‐type AgSbTe2 Thermoelectrics

Advanced Functional Materials, EarlyView.
The supercompliant lattice design enables the first realization of n‐type electrical transport in AgSbTe2 by overcoming intrinsic electron‐killer defects and exceeding the doping limits imposed by the conventional Hume–Rothery rule. Accordingly, the best performance n‐type Ag0.8Na0.3Sb0.6Bi0.4Te2 sample achieves a low κ of 0.27 W·m−1·K−1 that ...
