This year has seen the discovery of three new types of superconductivity, expanding the understanding of how electrons can pair to create a frictionless flow of electricity. These superconductors are all two-dimensional materials, which can be manipulated by stacking and twisting to exhibit various behaviors. The findings challenge traditional theories of superconductivity, particularly with one new form that defies previous expectations. Historically, superconductivity has been linked to low temperatures and phonon interactions, but recent discoveries suggest that diverse mechanisms may be at play, similar to how different species of birds fly. The research highlights the potential of two-dimensional materials, allowing physicists to explore superconductivity more flexibly and efficiently. Notably, a team at Columbia University confirmed superconductivity in a transition metal dichalcogenide (TMD) material, while another group at Cornell University discovered an unexpected form of superconductivity in TMDs without adding electrons. These advancements indicate that the landscape of superconductivity is broader than previously thought, with implications for future technologies such as lossless power grids and advanced transportation systems.
