Supersymmetry is a theoretical framework by which each fermion and boson has a corresponding accomplice particle, generally known as a superpartner. These superpartners share the identical vitality spectrum however differ of their spin properties. The transformations between these particles are ruled by mathematical operators referred to as supercharges. Though superpartners haven’t but been noticed experimentally, their discovery would have vital implications for elementary physics.
Twisted bilayer supplies, similar to graphene and transition metallic dichalcogenides, have attracted consideration for his or her uncommon digital and topological properties. On this examine, the authors examine how supersymmetry manifests in these programs by analysing completely different vitality modes related to twisted bilayers.
They discover that superpartners can exhibit each trivial and nontrivial topological vitality bands. Moreover, they exhibit that supersymmetry can spontaneously break resulting from interactions between charged particles, generally known as Coulomb interactions.
This analysis gives new insights into the interaction between topology, symmetry, and interactions in low-dimensional supplies, and opens up new potentialities for exploring supersymmetry in condensed matter programs.
