Quantum singularities in a solvable toy model

Year: 2024

Type: conference-paper

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.
