Structured light enables control of optical chirality and spin
What the study found A single tunable parameter can link Pancharatnam topology to paraxial spin-orbit coupling, allowing control of optical chirality and spin angular momentum (SAM, the spin part of light’s angular momentum). Why the authors say this matters The authors conclude that this provides a simple and material-independent route to generate and control optical…
LHCb measurements match expectations for B+ decay angular rates
—
What the study found The measured normalised decay rate of B+ → J/ψ(→ μ+ μ−)K+ as a function of the lepton helicity angle agrees with expectations. The study also reports that the LHCb Upgrade I detector response is understood to the precision needed for related measurements. Why the authors say this matters The authors conclude…
Magnetic charge changes orbits and waveforms near regular black holes
—
in AstrophysicsStudy explores how magnetic charge in regular black holes alters gravitational waveforms from periodic orbits, offering new constraints on black hole properties through gravitational wave.
