Supersymmetry in twisted bilayers of transition metallic dichalcogenides reveals power bands with each trivial and non-trivial topology and demonstrates spontaneous symmetry breaking pushed by Coulomb interactions
Supersymmetry is a theoretical framework through which each fermion and boson has a corresponding associate particle, often known as a superpartner. These superpartners share the identical power 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, corresponding 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 power modes related to twisted bilayers.
They discover that superpartners can exhibit each trivial and nontrivial topological power bands. Moreover, they exhibit that supersymmetry can spontaneously break as a result of interactions between charged particles, often known as Coulomb interactions.
This analysis supplies new insights into the interaction between topology, symmetry, and interactions in low-dimensional supplies, and opens up new prospects for exploring supersymmetry in condensed matter programs.
