Physics
It is now possible to most accurately measure the lifetime of beautiful electrically neutral mesons.
Comparison of new ATLAS results for B0 lifetime with previous ATLAS results and results from the LHCb, CMS, D0, CDF, Belle II, BaBar, and Belle experiments. Credit: ATLAS/CERN Collaboration with ATLAS at the Large Hadron Collider (LHC) yields new high-precision measurements of the lifetime of electrically neutral beautiful (B0) mesons (hadrons consisting of a bottom antiquark and a down quark).…

Stabilized ferrocene molecules create the world’s smallest electrically controlled molecular machine
A complex of ammonium-bound ferrocene (Fc-amm) and crown ether is built on a Cu(111) surface, and its sliding motion is activated by hole injection into the ferrocene group using scanning tunneling microscopy (STM). . Credit: Toyowa Yamada / Chiba University Artificial molecular machines are nanoscale machines made up of a few molecules and have the potential to transform fields such…

The road to new quantum devices: electrically defined quantum dots in zinc oxide
Structure of zinc oxide (ZnO) device. A two-dimensional electron gas (2DEG) is formed at the (Mg, Zn)O/ZnO interface. By applying voltage to the gate electrode, electrons can be confined within the quantum dot. (b) SEM image of the fabricated ZnO quantum dot device. Quantum dots are generated in the circled area.
