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 carry enough energy to be 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 deserve to be considered physically real because they carry energy, not merely serve as mathematical tools. Writing on Big Think, he situates the question within the long-running debate in quantum physics over what counts as real, such as the wavefunction or eigenstates. The piece offers a philosophical and physical case for treating fields as concrete entities rather than abstractions.

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.
