      abstract     = {The production of polarized proton beams with multi-GeV
                      energies in ultraintense laser interaction with targets is
                      studied with three-dimensional particle-in-cell simulations.
                      A near-critical density plasma target with prepolarized
                      proton and tritium ions is considered for the proton
                      acceleration. The prepolarized protons are initially
                      accelerated by laser radiation pressure before injection and
                      further acceleration in a bubblelike wakefield. The temporal
                      dynamics of proton polarization is tracked via the
                      Thomas-Bargmann-Michel-Telegdi equation and it is found that
                      the proton polarization state can be altered by both the
                      laser field and the magnetic component of the wakefield. The
                      dependence of the proton acceleration and polarization on
                      the ratio of the ion species is determined and it is found
                      that the protons can be efficiently accelerated as long as
                      their relative fraction is less than $20\%,$ in which case
                      the bubble size is large enough for the protons to obtain
                      sufficient energy to overcome the bubble injection
                      threshold.},
