’t Hooft anomaly matching condition and chiral symmetry breaking without bilinear condensate [PDF]
Journal of High Energy Physics, 2019 We explore 4-dimensional SU(N) gauge theory with a Weyl fermion in an irreducible self-conjugate representation. This theory, in general, has a discrete chiral symmetry.

Baryons and Chiral Symmetry [PDF]
International Journal of Modern Physics E, 2016 The relevance of chiral symmetry in baryons is highlighted in three examples in the nucleon spectroscopy and structure. The first one is the importance of chiral dynamics in understanding the Roper resonance. The second one is the role of chiral symmetry

Higher Structure of Chiral Symmetry. [PDF]
Commun Math PhysAbstract A recent development in our understanding of the theory of quantum fields is the fact that familiar gauge theories in spacetime dimensions greater than two can have non-invertible symmetries generated by topological defects. The hallmark of these non-invertible symmetries is that the fusion rule deviates from the usual group-like ...

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

Ultrasensitive Chiral Spectroscopy by Dynamical Symmetry Breaking in High Harmonic Generation [PDF]
Physical Review X, 2019 We propose and numerically demonstrate a new chiral spectroscopy method that is based on a universal system-independent mechanism of dynamical symmetry breaking in high harmonic generation (HHG).

Chiral symmetry restoration with three chiral partners
SciPost Physics Proceedings, 2022 I discuss the masses of chiral partners in the context of chiral symmetry restoration at finite temperature. Using the Nambu–Jona-Lasinio model I first remind the usual situation where two mesons of opposed parity become degenerate above the chiral ...

Noninvertible Chiral Symmetry and Exponential Hierarchies [PDF]
Physical Review X, 2022 We elucidate the fate of classical symmetries which suffer from abelian Adler-Bell-Jackiw anomalies. Instead of being completely destroyed, these symmetries survive as non-invertible topological global symmetry defects with worldvolume anyon degrees of ...

Experimental Evidence of Chiral Symmetry Breaking in Kekulé-Ordered Graphene. [PDF]
Physical Review Letters, 2021 The low-energy excitations of graphene are relativistic massless Dirac fermions with opposite chiralities at valleys K and K^{'}. Breaking the chiral symmetry could lead to gap opening in analogy to dynamical mass generation in particle physics.

Experimentally Detecting Quantized Zak Phases without Chiral Symmetry in Photonic Lattices. [PDF]
Physical Review Letters, 2021 Symmetries play a major role in identifying topological phases of matter and in establishing a direct connection between protected edge states and topological bulk invariants via the bulk-boundary correspondence. One-dimensional lattices are deemed to be

Halide-assisted differential growth of chiral nanoparticles with threefold rotational symmetry
Nature Communications, 2023 Enriching the library of chiral plasmonic nanoparticles that can be chemically mass-produced will greatly facilitate the applications of chiral plasmonics in areas ranging from constructing optical metamaterials to sensing chiral molecules and activating
