• Abstract: A quantum generalization of the Cooper-Fry recipe is proposed. The single-particle spectrum arising from relativistic collisions of particles and nuclei is calculated within the thermal quantum field theory framework. The starting point of consideration is the solution of the initial-value problem of particle emission from a space-like hypersurface. In the following steps, we obtain the single-particle spectrum using the ``smaller'' Green's function associated with the fireball medium. Based on this result, several specific examples of particle emission are considered.

  We study the large-scale dynamics of charged particles in a rapidly oscillating field and formulate its classical and quantum effective theory description. Remarkably, the action models the effects of general relativity on the motion of nonrelativistic particles, with the values of the emergent curvature and speed of light determined by the field spatial distribution and frequency.

• The strongly driven Fermi polaron [49.81410781350196]
  Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems. We take advantage of the clean setting of homogeneous quantum gases and fast radio-frequency control to manipulate Fermi polarons. We measure the decay rate and the quasiparticle residue of the driven polaron from the Rabi oscillations between the two internal states.

  We propose a model describing spin-half quantum particles in curved spacetime. We find that spin precesses in a normal Fermi frame, even in the absence of torsion. We also find that (elementary) fermions and antifermions are indistinguishable in gravity.

  We study the phenomenon of transmission across the singularity that separates the two half-cylinders. All the local realisations of the free (Laplace-Beltrami) quantum Hamiltonian are examined as non-equivalent protocols of transmission/reflection. This allows to comprehend the distinguished status of the so-called bridging' transmission protocol previously identified in the literature.

• Light emission is fundamentally tied to the quantum coherence of the emitting particle [0.0]
  We show that even in seemingly classical experimental regimes, light emission is tied to quantum properties of the emitting particles. By employing quantum electrodynamics, we unveil the role of the particle's coherent momentum uncertainty. We find instead that the shockwave's duration is fundamentally bound from below by the particle's coherent momentum uncertainty.

A modification of the propagator is proposed, in which the role of independent time parameters is taken by the time coordinates of the particles in Minkowski space.
