Astronomers claim first direct observation of vacuum birefringence in magnetar 1E 1547.0−5408, detecting up to 80% polarized X-rays. This confirms a 90-year-old QED prediction that intense magnetic fields polarize quantum vacuum.

By combining electron cooling of highly-charged ions in a Penning trap with deceleration and trapping of accelerator-produced highly-charged ions, new experiments pave the way for high-precision experiments in #QuantumElectrodynamics.

On the left are results from the one-shot energy analyzer following the interdigital H-type structure — a grainy blue circle with two roughly horizontal streaks of green, red, orange, and yellow. 36Ar18+ ions are separated by the magnetic field, with the low energy components located in the bottom streak and the high energy components in the top streak. On the right is a graph with the signal, which has arbitrary units, on the x-axis and intensity, shown as position in millimeters on the y-axis. The fully-decelerated components are marked green and the partially- or non-decelerated components are marked red.

For the first time, NASA's IXPE telescope has measured X-ray polarization around a magnetar at nearly three times the level any comparable source has produced — a result that only makes sense if empty

Quantum gravity corrections to the Lamb shift are substantially amplified by atomic acceleration, enabling low-energy tests of Planck-scale physics. Nonthermal effects can exceed thermal contributions by two orders of magnitude.

Science is difficult.

The great Richard Feynman shares how just because we cannot understand the results of the Scientific Method, doesn’t mean they are not true, in this discussion on QuantumElectrodynamics.
