Planck-Scale Effects on Global Symmetries: Cosmology of Pseudo-Goldstone Bosons [PDF]
, 2004 We consider a model with a small explicit breaking of a global symmetry, as suggested by gravitational arguments. Our model has one scalar field transforming under a non-anomalous U(1) symmetry, and coupled lo matter and to gauge bosons.

Abundant Symmetry-Breaking Solutions of the Nonlocal Alice–Bob Benjamin–Ono System
Complexity, 2020 The Benjamin–Ono equation is a useful model to describe the long internal gravity waves in deep stratified fluids. In this paper, the nonlocal Alice–Bob Benjamin–Ono system is induced via the parity and time-reversal symmetry reduction. By introducing an

The effective action of superrotation modes
Journal of High Energy Physics, 2021 Starting from an analysis of four-dimensional asymptotically flat gravity in first order formulation, we show that superrotation reparametrization modes are governed by an Alekseev-Shatashvili action on the celestial sphere.

Explicit Supersymmetry Breaking on Boundaries of Warped Extra Dimensions [PDF]
, 2003 Explicit supersymmetry breaking is studied in higher dimensional theories by having boundaries respect only a subgroup of the bulk symmetry. If the boundary symmetry is the maximal subgroup allowed by the boundary conditions imposed on the fields, then ...

$$ \mu -\tau $$ μ-τ reflection symmetry embedded in minimal seesaw
European Physical Journal C: Particles and Fields, 2018 We embed $$\mu -\tau $$ μ-τ reflection symmetry into the minimal seesaw formalism, where two right-handed neutrinos are added to the Standard Model of particle physics. Assuming that both the left- and right-handed neutrino fields transform under $$\mu -\

Dark matter from a complex scalar singlet: the role of dark CP and other discrete symmetries
Journal of High Energy Physics, 2021 We study the case of a pseudo-scalar dark matter candidate which emerges from a complex scalar singlet, charged under a global U(1) symmetry, which is broken both explicitly and spontaneously.

Holographic phonons by gauge-axion coupling
Journal of High Energy Physics, 2021 In this paper, we show that a simple generalization of the holographic axion model can realize spontaneous breaking of translational symmetry by considering a special gauge-axion higher derivative term.

Adding machine learning within Hamiltonians: Renormalization group transformations, symmetry breaking and restoration [PDF]
arXiv.org, 2020 We present a physical interpretation of machine learning functions, opening up the possibility to control properties of statistical systems via the inclusion of these functions in Hamiltonians.

Hidden symmetry protection for surface plasmon polaritons
Physical Review Research, 2023 In this study, we reveal the general mechanism of hidden symmetry protection for surface plasmon polaritons (SPPs). SPPs are protected at zero frequency when the dielectric-metal interface exhibits an exceptional symmetry.

Probing Left-Right Symmetry via Gravitational Waves from Domain Walls [PDF]
, 2022 We study the possibility of probing the scale of left-right symmetry breaking in the context of left-right symmetric models (LRSM). In LRSM, the right handed fermions transform as doublets under a newly introduced $SU(2)_R$ gauge symmetry. This, along with a discrete parity symmetry $\mathcal{P}$ ensuring identical gauge couplings of left and right ...
