• Title: Disappearing Without a Trace: The Arrows of Time in Kent's Solution to the Lorentzian Quantum Reality Problem
• Authors: Emily Adlam
• Abstract summary: Most existing proposals to explain the temporal asymmetries we see around us are sited within an approach to physics based on time evolution. But there may be other possibilities for explaining temporal asymmetries if we don't presuppose the time evolution paradigm. We argue that this approach potentially has the resources to explain the electromagnetic asymmetry, the thermodynamic asymmetry, the coarse-graining asymmetry, the fork asymmetry, the record asymmetry, and the cosmological asymmetry.

• Abstract: Most existing proposals to explain the temporal asymmetries we see around us are sited within an approach to physics based on time evolution, and thus they typically put the asymmetry in at the beginning of time in the form of a special initial state. But there may be other possibilities for explaining temporal asymmetries if we don't presuppose the time evolution paradigm. In this article, we explore one such possibility, based on Kent's `final-measurement' interpretation of quantum mechanics. We argue that this approach potentially has the resources to explain the electromagnetic asymmetry, the thermodynamic asymmetry, the coarse-graining asymmetry, the fork asymmetry, the record asymmetry, and the cosmological asymmetry, and that the explanations it offers may potentially be better than explanations appealing to a special initial state. Our hope is that this example will encourage further exploration of novel approaches to temporal asymmetry outside of the time evolution paradigm.

• Multiple crossing during dynamical symmetry restoration and implications for the quantum Mpemba effect [0.0]
  We show how, by tuning the initial state, the symmetry dynamics in free fermionic systems can display much richer behaviour than seen previously. In particular, for certain classes of initial states, including ground states of free fermionic models with long-range couplings, the entanglement asymmetry can exhibit multiple crossings.

  We find that recent time symmetric interpretations of quantum mechanics fail to respect event symmetry. We then use this model to resolve conceptual paradoxes with time symmetric quantum mechanics within an all-at-once', atemporal picture.

  Hawking's discovery that black holes can evaporate through radiation emission has posed a number of questions. We employ entanglement asymmetry as a modern, information-based indicator of symmetry breaking. Our findings imply that the emitted radiation is symmetric up to the Page time and then undergoes a sharp transition.

  We investigate the completion of a nonadiabatic evolution into a shortcut to adiabaticity for a quantum field confined within a one-dimensional cavity containing two movable mirrors. We achieve a smooth extension of the Moore functions that implements the STA. We draw attention to the existence of a comparable problem within nonrelativistic quantum mechanics.
