  • Researchers generated 16.7 nm wavelength extreme-ultraviolet Poincaré beams at the FERMI free electron laser without relying on optical elements. The method of in situ Poincaré beam production in free electron lasers enables straightforward flexibility in the orientation and balance of polarization states, and can be extended to other vector beams and to shorter wavelengths.

  • Predicting and controlling the (in)stability of thin shells are important tasks in many practical applications but hampered by the presence of imperfections. Here Yan et al. show that when the material composition is magnetic the conditions for collapse can simply be readjusted with external fields.
