What is Unveiling the Dirac feature in the Metallated Carbyne as a Potential Platform for Exploring Widely Separated Majorana Fermions about?

The realization of next-generation quantum computing devices is hindered by the formidable challenge of detecting and manipulating Majorana Fermion in nanomaterials. In this study, we explore a new approach of detecting Majorana Fermion in a metallated carbyne nanowire array. Through comprehensive optimizations, we successfully achieved a local magnetic moment exceeding 3{\mu}B, with the average magnetic moment of the entire metallated carbyne surpassing 1{\mu}B. Surprisingly, in the absence of spin-orbit coupling, the ferromagnetic Ru metallated carbyne, when coupled with a superconducting Ru substrate, is already able to demonstrate the symmetric opening of a Dirac gap at the gamma point. We discovered that the kink structure of the metallated carbyne plays a crucial role in modulating its topological properties. Moreover, we identified the origin of magnetic hybridization which is intricately linked to the distinctive features found in one-dimensional carbon structures. Our findings not only uncover the unconventional ferromagnetism observed in metallated carbyne but also present an exciting opportunity to realize carbon-based materials capable of hosting Majorana Zero Modes (MZ
