Halogen bond-modulated solid-state reordering and symmetry breaking of azahelicenes [PDF]

Nature Communications
Spontaneous symmetry breaking predominately occurs during the aggregation of discrete molecules in solution. Herein, we report a unique solid-state symmetry breaking process of dynamically chiral aza[4]helicenes that emerged in vacuum-driven ...

Left-right symmetry breaking: learning from the chicken [PDF]

Frontiers in Cell and Developmental Biology
Morphological left-right asymmetry of visceral organs in most cases reveals a typical arrangement. This implies directed symmetry breaking which is suggested to be based on the existence of structural chirality.

Symmetry Breaking of Molecules Triggered by Chiral Inorganic Nanostructures Without Organic Components [PDF]

Advanced Science
Chirality transfer has garnered significant attention due to its potential to revolutionize asymmetric synthesis of enantiopure compounds and to provide fundamental insights into molecular symmetry breaking, which is widely believed to underlie the ...

Interplay between nuclear chiral and reflection symmetry breakings revealed by the lifetime measurements in 76Br

Physics Letters B, 2022
Nearly degenerate positive-parity doublet bands and several E1 transitions between positive- and negative-parity bands have been identified in 76Br. These experimental observations are interpreted as the coexistence of chirality and octupole correlations,

Chirality transfer from a 3D macro shape to the molecular level by controlling asymmetric secondary flows

Nature Communications, 2022
External physical forces can bias a spontaneous symmetry breaking process but whether the shape of a reactor plays a role in chiral symmetry breaking processes is an open question. Here, the authors demonstrate chirality transfer from the chiral shape of

Gapped Chiral Fermions

Physical Review X, 2021
In principle, there is no obstacle to gapping fermions preserving any global symmetry that does not suffer a ’t Hooft anomaly. In practice, preserving a symmetry that is realized on fermions in a chiral manner necessitates some dynamics beyond simple ...

Non-Abelian anomalous constitutive relations of a chiral hadronic fluid [PDF]

EPJ Web of Conferences, 2022
We study the constitutive relations of a chiral hadronic fluid in presence of non-Abelian’t Hooft anomalies. Analytical expressions for the covariant currents are obtained at first order in derivatives in the chiral symmetric phase, for both two and ...

Chiral symmetry breaking by a non-Abelian external field in (2+1)-dimensions [PDF]

, 1997
We investigate the effect of a constant external non-Abelian field on chiral symmetry breaking in a (2+1)-dimensional Nambu-Jona-Lasinio model and in 3D QCD by solving the gap equation and the Bethe-Salpeter equation, and also by RG analysis. In the (2+1)

Nambu–Jona-Lasinio model in a parallel electromagnetic field

Physics Letters B, 2018
We explore the features of the UA(1) and chiral symmetry breaking of the Nambu–Jona-Lasinio model without the Kobayashi–Maskawa–'t Hooft determinant term in the presence of a parallel electromagnetic field. We show that the electromagnetic chiral anomaly
