• Title: Quantum singularities in a solvable toy model
• Authors: Miloslav Znojil,
• Abstract summary: It is proposed that the role of quantum singularities can be played by the so called Kato's exceptional-point spectral degeneracies. It is demonstrated that the singularities of classical physics (sampled by the Big Bang in cosmology) need not necessarily get smeared out after quantization.

• 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.

  A Planck scale inflationary era produces the scale invariant spectrum of inhomogeneities with very small tensor-to-scalar ratio of perturbations. Here we evoke the possibility that some of the major puzzles in cosmology would have an explanation rooted in quantum gravity.

• Quantum Mechanical description of Bell's experiment assumes Locality [91.3755431537592]
  Bell's experiment description assumes the (Quantum Mechanics-language equivalent of the classical) condition of Locality. This result is complementary to a recently published one demonstrating that non-Locality is necessary to describe said experiment. It is concluded that, within the framework of Quantum Mechanics, there is absolutely no reason to believe in the existence of non-Local effects.
