• Abstract: We develop an extension of special relativity in $1+3$ dimensional spacetime to account for superluminal inertial observers and show that such an extension rules out the conventional dynamics of mechanical point-like particles and forces one to use a field-theoretic framework. Therefore we show that field theory can be viewed as a direct consequence of extended special relativity.

  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.

  atom interferometric models often include relativistic effects only in an ad hoc fashion. We generalize special-relativistic center of mass and relative coordinates to obtain light-matter dynamics in curved spacetime. We obtain the Hamiltonian of a fully first-quantized two-particle atom interacting with the electromagnetic field in curved spacetime.

• Sentient observers and the ontology of spacetime [0.0]
  I show that, by the same criteria that led to Galilean and Special Relativity and gauge symmetries, there is no way to identify a unique set of observables that give the structure of space or spacetime. This indicates a strong connection between spacetime and the sentience of the observers, as anticipated by some early contributors to Special and General Relativity.

• Simulating superluminal propagation of Dirac particles using trapped ions [0.0]
  We propose to simulate the movement of a Dirac particle propagating with a superluminal velocity caused by the emergent Alcubierre warp drive spacetime using trapped ions. We demonstrate that the platform allows observing the tilted lightcone that manifests as a superluminal velocity, which is in agreement with the prediction of general relativity. The present scheme can be extended to simulate the Dirac equation in other exotic curved spacetimes.

• Interferometric Visibility in Curved Spacetimes [0.0]
  In [M. Zych et al., Nat. Commun. 2, 505 (2011), the authors predicted that the interferometric visibility is affected by a gravitational field in way that cannot be explained without the general relativistic notion of proper time. In this work, we start deriving the same effect using the unitary representation of the local Lorentz transformation in the Newtonian Limit. We show that the effect on the interferometric visibility due to gravity persists in different spacetime geometries.

This topological gravity is of the cohomological type, and it exhibits an $cal N=2$ extended BRST symmetry. We demonstrate a standard one-step BRST gauge-fixing of a theory whose fields are $g_ij$, $ni$ and $n$, and whose gauge symmetries consist of (i) the topological deformations of $g_ij$, and (ii) the ultralocal nonrelativistic limit of space
