Discrete time quantum walk of locally interacting walkers
Vikash Mittal, Tomasz Sowiński
In this work, we introduce a general form of a two-parameter family of local interactions between quantum walkers conditioned on the internal state of their coins. By choosing thei…

Spectrometry of Captured Highly Charged Ions Produced Following Antiproton Annihilations
F. P. Gustafsson, M. Volponi, J. Zielinski +61
We report a proof-of-principle study demonstrating the first capture and time-of-flight spectrometry of highly charged ions (HCIs) produced following antiproton annihilations in a…

Stability conditions for bound states in antiprotonic atoms
Fredrik Parnefjord Gustafsson, Daniel Pęcak, Tomasz Sowiński
We study the stability of bound antiprotons in close proximity to the atomic nucleus. Using experimental data from X-ray spectroscopy measurements of antiprotonic atom transitions,…
