Discrete R-symmetry anomalies in heterotic orbifold models
, 2007 Anomalies of discrete R-symmetries appearing in heterotic orbifold models are studied. We find that the mixed anomalies for different gauge groups satisfy the universal Green-Schwarz (GS) condition, indicating that these anomalies are canceled by the GS ...

The CP-symmetries of the 2HDM [PDF]
, 2019 We discuss the three different classes of CP-symmetries that can be realized in a two-Higgs-doublet model, CP1, CP2 and CP3. We express conditions for realizing these symmetries in terms of masses and couplings of the model, thereby providing a way of ...

Non-Abelian Discrete Symmetries in Particle Physics [PDF]
, 2010 We review pedagogically non-Abelian discrete groups, which play an important role in the particle physics. We show group-theoretical aspects for many concrete groups, such as representations, their tensor products.

Ultraviolet–Visible Spin‐Resolved Chip‐Scale Spectroscopy
Advanced Functional Materials, EarlyView.By harnessing phase, wavelength, and spin multiplexing, the proposed meta‐spectrometer enables spin‐resolved spectral analysis within a compact footprint. The presented dual‐band (320–450 nm) spin‐resolved meta‐spectrometer features enhance optical functionality, allowing for the simultaneous discrimination of spectral content and spin states of light ...

Double Helical Plasmonic Antennas
Advanced Functional Materials, EarlyView.Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Unification of flavor, CP, and modular symmetries
Physics Letters B, 2019 Flavor symmetry plays a crucial role in the standard model of particle physics but its origin is still unknown. We develop a new method (based on outer automorphisms of the Narain space group) to determine flavor symmetries within compactified string ...

Discrete symmetry and GUT breaking [PDF]
The European Physical Journal C, 2002 We study the supersymmetric GUT models where the supersymmetry and GUT gauge symmetry can be broken by the discrete symmetry. First, with the ansatz that there exist discrete symmetries in the branes' neighborhoods, we discuss the general reflection $Z_2$ symmetries and GUT breaking on $M^4\times M^1$ and $M^4\times M^1\times M^1$. In those models, the

A generalization of decomposition in orbifolds
Journal of High Energy Physics, 2021 This paper describes a generalization of decomposition in orbifolds. In general terms, decomposition states that two-dimensional orbifolds and gauge theories whose gauge groups have trivially-acting subgroups decompose into disjoint unions of theories ...
