Electrically Tunable Heliconical Smectic Superstructure in Polar Fluids
Advanced Materials, EarlyView.Strong dipole–dipole interactions give rise to an emergent polar smectic phase with spontaneous chiral symmetry breaking. This resulting polar heliconical smectic superstructure enables novel functionalities in polar fluids, such as color modulation driven by electric field strength and frequency, as well as second‐harmonic generation amplification ...

Chiral symmetry and pion polarizabilities
Physics Letters B, 1992 We use chiral perturbation theory including 1-loop contributions to derive formulae needed to deduce pion polarizabilities from γπ->γπ and γγ->ππ data. We deduce for the first time values for the π^+- and π^0 polarizabilities from ππ production data, and compare these new results to chiral symmetry predictions.

Advanced Materials, EarlyView.Hydration‐induced symmetry breaking transforms layered LiInP2S6${\rm LiInP}_2{\rm S}_6$ from a nonpolar to a chiral‐polar phase, producing a giant enhancement of non‐resonant second‐harmonic generation. The reversible tuning of polar order through molecular intercalation establishes a strategy for dynamically controlling nonlinear optical ...

Tuning chirality amplitude at ultrafast timescales in chiral CsCuCl_{3}
Physical Review ResearchChirality is a fundamental symmetry concept relevant to many scientific fields. It describes discrete states, i.e., left-handed, right-handed, or achiral. In contrast to this discrete classification, objects can be continuously distorted. To describe the

Advanced Materials, EarlyView.α‐MoO3 is established as a high‐index, low‐loss anisotropic platform bridging mid‐infrared polaritonics and ultraviolet‐visible nanophotonics. Spectroscopic ellipsometry and calculations reveal refractive indices exceeding 3.9, with the largest in‐plane birefringence among transparent layered crystals at 425–500 nm, enabling zero‐order UV waveplates ...

Chiral Symmetry and Nuclear Interactions [PDF]
Few-Body SystemsAbstractAbout 3 decades ago, Steven Weinberg came up with an idea of using the effective chiral Lagrangian to describe nuclear interactions, which has had a long-lasting impact on nuclear physics. Here, I will reflect on what has been learned since that time about the role of chiral symmetry in this context and discuss achievements and challenges in ...

Chiral Altermagnetic Magnetoelectrics
Advanced Materials, EarlyView.In this work, we introduce a previously unexplored class of magnetoelectric materials, which we term chiral altermagnetic magnetoelectrics, in which structural chirality and Néel‐vector‐driven polarization are intrinsically coupled in nonpolar altermagnetic systems.
