Asymmetric autocatalysis. Chiral symmetry breaking and the origins of homochirality of organic molecules. [PDF]
Proc Jpn Acad Ser B Phys Biol Sci, 2019 Biological homochirality, such as that of l-amino acids, has been a puzzle with regards to the chemical origin of life. Asymmetric autocatalysis is a reaction in which a chiral product acts as an asymmetric catalyst to produce more of itself in the same ...

Anomaly constraint on massless QCD and the role of Skyrmions in chiral symmetry breaking [PDF]
Journal of High Energy Physics, 2018 We discuss consequences of the ’t Hooft anomaly matching condition for Quantum Chromodynamics (QCD) with massless fundamental quarks. We derive the new discrete ’t Hooft anomaly of massless QCD for generic numbers of color N c and flavor N f , and an ...

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).

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 ...

’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.

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.

Chiral Symmetry Breaking for Deterministic Switching of Perpendicular Magnetization by Spin-Orbit Torque. [PDF]
Nano letters (Print), 2020 Symmetry breaking is a characteristic to determine which branch of a bifurcation system follows upon crossing a critical point. Specifically, in spin-orbit torque (SOT) devices, a fundamental question arises: how can the symmetry of the perpendicular ...

Inhomogeneous phases in the quark-meson model with explicit chiral-symmetry breaking [PDF]
The European Physical Journal Special Topics, 2020 We investigate the existence of inhomogeneous chiral phases in the quark-meson model with explicit chiral-symmetry breaking. We find that the inhomogeneous region shrinks with increasing pion masses but survives for the physical value of mπ.
