Background:

• Domain walls (DWs) are topological defects arising from symmetry-breaking phase transitions.
• DWs are fundamental but underexplored in optical systems with higher-order dispersion.
• Pure-quartic (PQ) solitons, characterized by unique energy-width scaling, emerge from quartic group-velocity dispersion (GVD) and Kerr nonlinearity.

Purpose of the Study:

• To investigate and report solutions for PQ-DW solitons in optical media with PQ GVD.
