Researchers have made exciton wavefunctions directly visible in an experimental advance reported by Physics World. Excitons — bound pairs of electrons and holes that govern optical properties of semiconductors — have until now been characterised indirectly. Being able to image their wavefunctions could improve understanding of light-matter interactions and support development of optoelectronic and quantum materials.
- 2Do quantum fields' energy prove they are real?▼Quantum fields carry energy. Does that prove that they’re real? In quantum physics, we often argue over "what is real?"
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.

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.

A science writer is revisiting the long-running debate over what counts as real in quantum physics. While interpretations argue over whether the wavefunction or eigenstates are physically real, quantum fields have a stronger claim: they carry energy, making them hard to dismiss as mere bookkeeping. The argument is drawing engagement from physics enthusiasts and prompting familiar debates over interpretation versus measurement.
