Quantum singularities in a solvable toy model
arXiv:2407.14672 · doi:10.1088/1742-6596/2912/1/012012
Abstract
Via elementary examples it is demonstrated that the singularities of classical physics (sampled by the Big Bang in cosmology) need not necessarily get smeared out after quantization. It is proposed that the role of quantum singularities can be played by the so called Kato's exceptional-point spectral degeneracies.
