• Abstract: In this paper, we investigate the consequences of maximal length as well as minimal momentum scales on nonlocal correlations shared by two parties of a bipartite quantum system. To this aim, we rely on a general phenomenological scheme which is usually associated with the non-negligible spacetime curvature at cosmological scales, namely the extended uncertainty principle. In so doing, we find that quantum correlations are degraded if the deformed quantum mechanical model mimics a positive cosmological constant. This opens up the possibility to recover classicality at sufficiently large distances.

• Entropy production due to spacetime fluctuations [0.0]
  We consider a non-relativistic quantum system interacting with gravitational waves. We employ the consistent histories approach to quantum mechanics to define a fluctuation relation for this system. As a result, thermodynamic entropy must be produced in the system due to its unavoidable interaction with the quantum fluctuations of spacetime.

  We study phase transitions occurring in the stationary state of the dynamics of integrable many-body non-Hermitian Hamiltonians. We observe that the entanglement phase transitions occurring in the stationary state have the same nature as that occurring in the vacuum of the non-hermitian Hamiltonian.

• Quantum fluctuations and correlations in open quantum Dicke models [0.0]
  In the vicinity of ground-state phase transitions quantum correlations can display non-analytic behavior and critical scaling. Here we consider as a paradigmatic setting the superradiant phase transition of the open quantum Dicke model. We show that local dissipation, which cannot be treated within the commonly employed Holstein-Primakoff approximation, rather unexpectedly leads to an enhancement of collective quantum correlations.

  New developments in the analysis of the most recent Planck data suggest that the primordial power spectrum has a cutoff associated with the first quantum fluctuation. We demonstrate that the birth of quantum fluctuations at the Planck scale would have been a process' supplanting the need for a measurement' in quantum mechanics.
