      abstract     = {Orbitronics is an emerging and fascinating field that
                      explores the utilization of the orbital degree of freedom
                      ofelectrons for information processing. An increasing number
                      of orbital phenomena are being currently discovered, with
                      spin-orbit coupling mediating the interplay between orbital
                      and spin effects, thus providing a wealth of control
                      mechanisms and device applications. In this context, the
                      orbital analog of the spin Dzyaloshinskii-Moriya interaction
                      (DMI), i.e., orbital DMI, deserves to be explored in depth
                      since it is believed to be capable of inducing chiral
                      orbital structures. Here, we unveil the main features and
                      microscopic mechanisms of the orbital DMI in a
                      two-dimensional square lattice using a tight-binding model
                      of t2g orbitals in combination with the Berry phase theory.
                      This approach allows us to investigate and transparently
                      disentangle the role of inversion symmetry breaking,
                      strength of orbital-exchange interaction, and spin-orbit
                      coupling in shaping the properties of the orbital DMI. By
                      scrutinizing the band-resolved contributions, we are able to
                      understand the microscopic mechanisms and guiding principles
                      behind the orbital DMI and its anisotropy in two-dimensional
                      magnetic materials, and uncover a fundamental relation
                      between the orbital DMI and its spin counterpart, which is
                      currently being explored very intensively. The insights
                      gained from our work contribute to advancing our knowledge
                      of orbital-related effects and their potential applications
                      in spintronics, providing a path for future research in the
                      field of chiral orbitronics.},
