Chiral Symmetry Breaking and Pattern Formation in Two-Dimensional Films
, 1992 Thin films of organic molecules, such as Langmuir monolayers and freely suspended smectic films, can exhibit a spontaneous breaking of chiral symmetry. This chiral symmetry breaking can occur through at least three possible mechanisms: (1) the relation ...

Measuring the Hall Effect in Hysteretic Materials
Advanced Materials, EarlyView.The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

Symmetry-controlled hybrid chiral-omega bianisotropy in knot-particle metasurface
Physical Review ResearchHybrid chiral-omega bianisotropic responses are challenging to achieve within a single metamaterial layer due to their distinct symmetry requirements.

D7 brane embeddings and chiral symmetry breaking
, 2005 We study the embedding of D7 brane probes in five geometries that are deformations of AdS5 × S5. Each case corresponds to the inclusion of quark fields in a dual gauge theory where we are interested in investigating whether chiral symmetry breaking ...

Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?
Advanced Materials, EarlyView.The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.

Chiral Oscillations and Spontaneous Mirror Symmetry Breaking in a Simple Polymerization Model
, 2020 The origin of biological homochirality—defined as the preference of biological systems for only one enantiomer—has widespread implications in the study of chemical evolution and the origin of life.

Testing chiral symmetry breaking at DAΦNE [PDF]
Nuclear Physics A, 1997 The spontaneous breakdown of the chiral symmetry of the QCD Lagrangian ensures that $ππ$ interactions are weak at low energies. How weak depends on the nature of explicit symmetry breaking. Measurements of $K_{e4}$ decays at DA$Φ$NE will provide a unique insight into this mechanism and test whether the $q{\overline q}$--condensate is large or small.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix
Advanced Materials, EarlyView.3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Mirror symmetry breaking and chiral amplification of ethylenediammonium sulfate crystals [PDF]
, 2008 Chiral symmetry breaking is a process that generates one enantiomer largely over the other when a racemic mixture is expected. In nature, one handedness is preferred over the other and it has been shown that chiral molecules, including amino acids, can ...
