Chiral Dynamics in Nuclear Systems

, 2003
A survey is given on selected topics concerning the role of spontaneous chiral symmetry breaking in low-energy QCD, and its dynamical implications for nuclear systems. This includes aspects of chiral thermodynamics (the temperature and density dependence

Ferroelectric Fluids for Nonlinear Photonics: Evaluation of Temperature Dependence of Second‐Order Susceptibilities

Advanced Optical Materials, EarlyView.
Nonlinear optical susceptibilities of five different materials that exhibit the ferroelectric nematic phase, as well as smectic A ferroelectric phase, are determined. The materials investigated include archetypal molecular architectures as well as mixtures showing room‐temperature ferroelectric phases.

Locating quark-antiquark string breaking in QCD through chiral symmetry restoration and Hawking-Unruh effect

Physics Letters B
The relationship between QCD and the string model offers a valuable perspective for exploring the interaction potential between quarks. In this study, we investigate the restoration of chiral symmetry in connection with the Unruh effect experienced by ...

Scars in Dirac fermion systems: the influence of an Aharonov–Bohm flux

New Journal of Physics, 2017
Time-reversal ( ${ \mathcal T }$ -) symmetry is fundamental to many physical processes. Typically, ${ \mathcal T }$ -breaking for microscopic processes requires the presence of magnetic field.

Spontaneous chiral symmetry breaking in early molecular networks

Biology Direct, 2010
Background An important facet of early biological evolution is the selection of chiral enantiomers for molecules such as amino acids and sugars. The origin of this symmetry breaking is a long-standing question in molecular evolution.

Rough Gauge Fields, Smearing and Domain Wall Fermions

, 2004
At a fixed lattice spacing, as determined by say m_\rho, adding additional fermion flavors to a dynamical simulation produces rougher gauge field configurations at the lattice scale.

Probing Ultrafast Coherent Bandgap Modulation in Monolayer WSe2 by Nonlinear Optics

Advanced Optical Materials, EarlyView.
This work sheds light on how resonant nonlinear optics blursthe line between perturbative and non‐perturbative nonlinear optics. Measured deviationsfrom the quadratic second‐harmonic scaling near the excitonic resonance arisefrom optical Stark and Bloch‐Siegert shifts. The experimental results arefurther underpinned by analytical and numerical analysis

Quark running mass and vacuum energy density in truncated Coulomb gauge QCD for five orders of magnitude of current masses

, 2010
We study in detail the effect of the finite current quark mass on chiral symmetry breaking, in the framework of truncated Coulomb gauge QCD with a linear confining quark-antiquark potential. In the chiral limit of massless current quarks, the breaking of

Tunable Patterned Blue Phase Liquid Crystals Based on Lithographic Process Technology

Advanced Optical Materials, EarlyView.
A patterned blue phase liquid crystal device with electrically driven, localized bistability is demonstrated using a cost‐efficient photolithographic dual‐alignment process. The device switches between a high‐contrast patterned state and a uniform reflective state.
