abstract = "The origins of ultra-high-energy cosmic rays (E \≳ 1019 eV)
are a mystery and still under debate in astroparticle physics. In
recent years some efforts were made to understand their nature. In
this contribution we consider the possibility of Some Soft Gamma
Repeaters (SGRs) and Anomalous X-ray Pulsars (AXPs) beeing white
dwarf pulsars, and show that these sources can achieve large
electromagnetic potentials on their surface that accelerate
particle almost at the speed of light, with energies E \∼
1020-21 eV. The sources SGRs/AXPs considered as highly magnetized
white dwarfs are well described in the Hillas diagram, lying close
to the AR Sorpii and AE Aquarii which are understood as white
dwarf pulsars.",
