Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

open access: yesAdvanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

Radiative neutrino mass models from non-invertible selection rules

open access: yesJournal of High Energy Physics
We apply non-invertible selection rules coming from a fusion algebra to radiative neutrino mass models where fields are labeled by the elements in the algebra.

Minimal inverse-seesaw mechanism with Abelian flavour symmetries

open access: yesJournal of High Energy Physics, 2021
We study the phenomenology of the minimal (2, 2) inverse-seesaw model supplemented with Abelian flavour symmetries. To ensure maximal predictability, we establish the most restrictive flavour patterns which can be realised by those symmetries. This setup

S3-flavour symmetry as realized in lepton flavour violating processes [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2008
A variety of lepton flavour violating effects related to the recent discovery of neutrino oscillations and mixings is here systematically discussed in terms of an S_3-flavour permutational symmetry. After a brief review of some relevant results on lepton masses and mixings, that had been derived in the framework of a Minimal S_3-Invariant Extension of ...

Flexible Unusual Ternary‐Component Graded‐Modulus Dielectric Films with High‐Density Capacitive Energy Storage

open access: yesAdvanced Science, EarlyView.
Hierarchical PP–LSR107–BaTiO3 nanocomposite films are fabricated by one‐step extrusion and stretching for roll‐to‐roll manufacture, combining high energy storage and processing flexibility. LSR107 surrounds BaTiO3‐rich regions, locating amorphous PP, decreasing defects, and introducing deep traps that homogenize the electric field and suppress charge ...

Neutrino masses and lepton flavour violating phenomena in the MSSM [PDF]

open access: yes, 2007
The most general supersymmetric model with minimal particle content and an additional discrete Ƶ(_3) symmetry, which allows lepton number violating terms, is considered. In this model, we calculate at the level of one-loop the resulting Majorana neutrino

Neuromorphic Near‐Sensor and In‐Sensor Computing Enabled by Next‐Generation Material‐Based Sensors

open access: yesAdvanced Science, EarlyView.
This Review presents a structural framework that classifies neuromorphic sensing into near‐sensor and in‐sensor architectures, clarifying physical coupling between sensing and computation. The framework connects neural and synaptic device functions with recent advances in optical, mechanical, and chemical sensing, compares energy consumption and ...

Weak scale right-handed neutrino as pseudo-Goldstone fermion of spontaneously broken U 1 L μ − L τ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$

open access: yesJournal of High Energy Physics, 2021
Possibility of a Right-Handed (RH) neutrino being a Goldstone fermion of a spontaneously broken global U(1) symmetry in a supersymmetric theory is considered.

ON QUARKS AND FLAVOR SYMMETRY [PDF]

open access: yesInternational Journal of Modern Physics A, 2008
Hadronic spectroscopy can be introduced to students and developed rather far without requiring SU(N) flavor symmetry. In such a "minimalist" presentation, we are naturally led to comment and clarify the concept of the "generalized" Pauli principle.
