The Aligned two-Higgs Doublet model [PDF]

, 2010
In the two-Higgs-Doublet model the alignment of the Yukawa flavour matrices of the two scalar doublets guarantees the absence of tree-level flavour-changing neutral couplings.

Multiple realizations of modular flavor symmetries and their phenomenology

Journal of High Energy Physics
We point out that specifying the finite modular group does not uniquely fix a modular flavor symmetry. We illustrate this using the finite modular group T′. Otherwise equivalent models based on different T′ lead to modular forms with different properties

Neutrino Mixings and the S4 Discrete Flavour Symmetry

, 2012
Discrete non-Abelian Symmetries have been extensively used to reproduce the lepton mixings. In particular, the S4 group turned out to be suitable to describe predictive mixing patterns, such as the well-known Tri-Bimaximal and the Bimaximal schemes ...

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

Advanced 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 ...

Flavor symmetries from modular subgroups in magnetized compactifications

Journal of High Energy Physics
We study the flavor structures of zero-modes, which are originated from the modular symmetry on T 1 2 × T 2 2 $$ {T}_1^2\times {T}_2^2 $$ and its orbifold with magnetic fluxes. We introduce the constraint on the moduli parameters by τ 2 = Nτ 1, where τ i

The mathematical structure of U-spin amplitude sum rules

Journal of High Energy Physics, 2022
We perform a systematic study of SU(2) flavor amplitude sum rules with particular emphasis on U-spin. This study reveals a rich mathematical structure underlying the sum rules that allows us to formulate an algorithm for deriving all U-spin amplitude sum

Chiral gauged fermions on a lattice [PDF]

, 2000
The chiral fermion model with local multifermion interactions proposed in Nucl. Phys. B486 (1997) 282 and Phys. Rev. D61 (2000) 054502 processes an exact SU_L(2) chiral gauge symmetry and SU_L(2) by U_R(1) chiral flavour symmetry on a lattice and a ...

Systematic Metabolic Engineering and Model‐Guided Optimization for High‐Level Production of L‐Theanine From Xylose in Escherichia Coli

Advanced Science, EarlyView.
This study is pioneering in constructing the shortest known synthetic pathway for L‐theanine production from xylose within E coli. Through comprehensive metabolic engineering strategies, our engineered strain achieved the highest reported L‐theanine titer from xylose, with a titer of 95.42 g/L, and a yield of 0.55 g/g.

Fermion masses, critical behavior and universality

Journal of High Energy Physics, 2023
We look for signals of critical behavior in the Yukawa sector. By reviewing a set of models for the fermion masses, we select those where a symmetry-breaking order parameter sits at a transition point between a disordered phase and an ordered one.
