Self-organized length scales beyond the linear Talbot effect.

In a collaboration with the INPHYNI in Nice and the TU Vienna which just appeared in Physical Review A we are looking now at the interplay of diffraction within the atomic cloud and diffraction in vacuum. It turns out that for most situations it is sufficient to look at the linear Talbot effect but things get more involved, if one puts the mirror “into the cloud”. If you are curious, how to do this and what the resulting length scales are, please look at Phys. Rev. A 111, 063506.

Spin Polarization in InGaAs quantum dots for spin-optoelectronics.

New paper in Applied Physics Letter on how the efficiency of introducing a spin polarization in InGaAs quantum dots depends on pump wavelength. Unfortunately, the wavelengths for best spin polarization and best quantum efficiency are not the same. If you are interested, please look at Appl. Phys. Lett. 126, 191102 (2025).
