      abstract     = {Ladder models of ultracold atoms offer a versatile platform
                      for the experimental and theoretical study of different
                      phenomena and phases of matter linked to the interplay
                      between artificial gauge fields and interactions. Strongly
                      correlated helical states are known to appear for specific
                      ratios of the particle and magnetic flux densities, and they
                      can often be interpreted as a one-dimensional limit of
                      fractional quantum Hall states, thus being called
                      pretopological. Their signatures, however, are typically
                      hard to observe due to the small gaps characterizing these
                      states. Here we investigate bosonic ladder models at filling
                      factor ν=1. Based on bosonization, renormalization group,
                      and matrix product state simulations we pinpoint two
                      strongly correlated helical phases appearing at this
                      resonance. We show that one of them can be accessed in
                      systems with two-species hardcore bosons and on-site
                      repulsions only, thus amenable for optical lattice
                      experiments. Its signatures are sizable and stable over a
                      broad range of parameters for realistic system sizes.},
