wavefunction

A new study published in Nature reports that quantum geometry can enhance superconductivity, with superpotential effects producing stronger superconducting states and unusually robust stiffness. The finding suggests that the geometric properties of quantum wavefunctions, not just band structure, can be used to engineer materials that superconduct more stably. Physicists are discussing the work as a potential route to designing next-generation superconductors.

Astrophysicist Ethan Siegel argues that quantum fields have a stronger claim to physical reality than other contested concepts in quantum physics, such as the wavefunction or eigenstates, because they carry energy. His essay revisits the long-running debate over what counts as 'real' in quantum theory and suggests energy transfer is a compelling argument for taking fields as more than mathematical tools.
