• Abstract: A general structure of unitary evolution (evaporation) of the black hole, respecting causality imposed by the event horizon (semicausality), has been derived and presented in the language of quantum circuits. The resulting consequences for the evolution of the corresponding entanglement entropy and the entropy curve have been determined. As an illustration of the general scheme, two families of qubit toy models have been discussed: tensor product models and controlled non-product models.

• Generalised Hydrodynamics description of the Page curve-like dynamics of a freely expanding fermionic gas [0.0]
  We study the evolution of entanglement entropy during evaporation of a black hole. We find that the growth of entanglement is linear and universal, i.e. independent of the details of the defect. Our study shows the power of the semiclassical approach and could be relevant for discussions on the resolution of the black hole information paradox.

  We show the ability to restore states of quantum systems from evolution induced by quantum dynamical semigroups perturbed by covariant measures. Our procedure describes reconstruction of quantum states transmitted via quantum channels and as a particular example can be applied to reconstruction of photonic states transmitted via optical fibers.

  We introduce a broader class of non-Hermitian Hamiltonian deformations in a nonrelativistic setting. We relate the time evolution operator and the time-evolving density matrix in the undeformed and deformed theories. As the dissipative evolution of a quantum system can be conveniently described in Liouville space, we discuss the spectral properties of the Liouvillians.

We motivate and discuss a class of tractable microstate models of black holes which can illuminate how the black hole complementarity principle can emerge operationally.

  We compute the geometric phases acquired in both unitary and dissipative Jaynes-Cummings models. In the dissipative model, the non-unitary effects arise from the outflow of photons through the cavity walls. We show the geometric phase is robust, exhibiting a vanishing correction under a non-unitary evolution.

  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.
