• Abstract: Recently Dragan and Ekert [New. J. Phys 22, 033038, 2020] presented arguments that probabilistic dynamics inherent in the realm of quantum physics is related to the propagation of superluminal particles. Moreover they argue that existence of such particles is a natural consequence of the principle of relativity. We show that the proposed extension of Lorentz transformation can be interpreted in natural way without invoking superluminal phenomena.

  We study the appearance of fermion condensates for self-interacting Dirac fermions. We show that the combined breakdown of time-reversal symmetry due to the expanding spacetime, and parity due to a pseudo-scalar condensate, manifest through the structure of the light-cone-like propagation of entanglement in this analogue cQFT.

  We show that, when a wavefunction is boosted, its tails travel one to the past and the other to the future. The surprising implication is that, in a quantum world, decay probabilities can never be Lorentz-invariant.

  We show that decoherence due to the presence of a detector propagates with the speed of light in terms of a retarded Green's function. The quantum nature of fields, such as quantum fluctuations or emission of gravitons expressed in terms of the Keldysh Green's function also play important roles in the mechanism of decoherence due to on-shell particle creation.

Our results hold even if the symmetry of space and time is Galilean. We present a new experiment for testing the quantum nature of the gravitational field.
