Jul 3, 2024 · Helicity is a topological invariant of massless particles: C=-2h. Eric Palmerduca, Hong Qin. There is an elementary but indispensable relationship between the topology and geometry of massive particles. The geometric spin s is related to the topological dimension of the internal space V by dim V = 2s + 1.
1 day ago · Hong Qin; A Failed Relocation. Posted on July 15, 2024 by Hong Qin. Starting in July I start my internship in Flushing. I have been looking for a way to change the subject of my study from the markets in Sunset Park to the ones on Flushing Main Street. However, the difference between Sunset Park and Flushing communities prevents this change.

5 days ago · Precision measurements of anomalous spin-dependent interactions are often hindered by magnetic noise and other magnetic systematic effects. Atomic comagnetometers use the distinct spin precession of two species and have emerged as important tools for effectively mitigating the magnetic noise. Nevertheless, the operation of existing comagnetometers is limited to very low-frequency noise commonly below 1 Hz. Here, we report a new type of atomic comagnetometer based on a magnetic noise self ...

1 day ago · Until the 5th century bce, China was dominated by the central-plain power Wei, a successor to Jin, and by the eastern power Qi, a wealthy state with a new ruling house. Qin remained a secondary power until after the great reforms of Xiaogong (361–338 bce) and Shang Yang (Wei Yang).
