Optical study of excitonic complexes in transition metal dichalcogenides monolayers by Bao, Di

“…Transition metal dichalcogenides (TMDs) monolayers such as MX2 (M = Mo, W; X = S, Se) feature strong exciton properties and spin-valley physics. As a result of strong quantum- and dielectric confinement in single atomic layer of TMD materials, the photoexcited electrons and holes are tightly bound via Coulomb interaction to form excitonic complexes such as charged excitons (trions), biexcitons that offer great opportunities to study many-body physics. …”

Harmonic Spinors in the Ricci Flow by Baldauf, Julius

“…Further, a sharp parabolic Hitchin–Thorpe inequality for simply-connected, spin 4-manifolds is proven. From this, it follows that the normalized Ricci flow on any exotic K3 surface must become singular.…”

GWTC-2.1: Deep extended catalog of compact binary coalescences observed by LIGO and Virgo during the first half of the third observing run

“…We also expand the population of binaries with significantly asymmetric mass ratios reported in GWTC-2 by an additional two events (the mass ratio is less than 0.65 and 0.44 at 90% probability for GW190403_051519 and GW190917_114630 respectively), and find that two of the eight new events have effective inspiral spins χ eff > 0 (at 90% credibility), while no binary is consistent with χ eff < 0 at the same significance. …”

Microwave tunable dielectric properties of multilayer CNT membranes for smart applications by Liu, L., Yang, Z. H., Kong, Ling Bing, Yin, W. Y., Wang, S.

“…Multilayer multiwall carbon nanotube (MWCNT) silicone composite membranes with thickness greater than 10 μm were prepared with a spin-coating method. Dielectric permittivity and tunability of the circular membranes were measured from 0.1 to 7 GHz by using a single-port coaxial line method. …”
