The Narrowing of Charge Balance Function and Hadronization Time in Relativistic Heavy Ion Collisions
The widths of charge balance function in high energy hadron-hadron and
relativistic heavy ion collisions are studied using the Monte Carlo generators
PYTHIA and AMPT, respectively. The narrowing of balance function as the
increase of multiplicity is found in both cases. The mean parton-freeze-out
time of a heavy-ion-collision event is used as the characteristic hadronization
time of the event. It turns out that for a fixed multiplicity interval the
width of balance function is consistent with being independent of hadronization
time.Comment: 4 pages, 7 figure
DNA nanotechnology-enabled chiral plasmonics: from static to dynamic
In this Account, we discuss a variety of static and dynamic chiral plasmonic
nanostructures enabled by DNA nanotechnology. In the category of static
plasmonic systems, we first show chiral plasmonic nanostructures based on
spherical AuNPs, including plasmonic helices, toroids, and tetramers. To
enhance the CD responses, anisotropic gold nanorods with larger extinction
coefficients are utilized to create chiral plasmonic crosses and helical
superstructures. Next, we highlight the inevitable evolution from static to
dynamic plasmonic systems along with the fast development of this
interdisciplinary field. Several dynamic plasmonic systems are reviewed
according to their working mechanisms.Comment: 7 figure
