• Abstract: Scar states are special finite-energy density, but non-thermal states of chaotic Hamiltonians. We argue that all holographic quantum field theories, including $\mathcal{N}=4$ super Yang--Mills, have scar states. Their presence is tied to the existence of non-topological, horizonless soliton solutions in gravity: oscillons and a novel family of excited boson stars. We demonstrate that these solutions have periodic oscillations in the correlation functions and posses low-entanglement entropy as expected for scar states. Also we find that they can be very easily prepared with Euclidean path integral.

  A periodically driven (Floquet) system in the absence of any conservation law heats to a featureless infinite temperature' state. Here, we find--for a clean and interacting generic spin chain--that this can be prevented by the emergence of it approximate but stable conservation-laws not present in the undriven system. We show numerically, it in the thermodynamic limit,' that when required by these emergent conservation-laws, the entanglement-entropy density of an infinite subsystem remains zero.

• Quantum scars in many-body systems [28.32223907511862]
  We show that quantum mechanics hinders chaos in many-body systems. Although the quantum eigenstates are thermal and strongly entangled, exponentially many of them are scarred. Scarring makes the system more likely to be found on an orbit it was on, retaining a memory of its past and thus weakly breaking ergodicity.

• Holographic Quantum Scars [0.0]
  We consider two-dimensional conformal field theories and use their dynamical symmetries, naturally realized through the Virasoro algebra, to construct scarred states. A geometrical interpretation allows us to compute the expectation value of the stress tensor and entanglement entropy of these scarred states. We identify fixed points on the CFT plane associated with divergent or vanishing entanglement entropy in the limit where the scarred states have infinite energy.

  We show that the probability of having a many-body scar state with entanglement entropy satisfying a sub-volume scaling law decreases double exponentially as the system size. Our results provide a quantitative argument for the disappearance of scar states in interacting fermion systems.

• Is negative kinetic energy meta-stable? [62.997667081978825]
  We explore the possibility that theories with negative kinetic energy (ghosts) can be meta-stable up to cosmologically long times. In classical mechanics, ghosts undergo spontaneous lockdown rather than run-away if weakly-coupled and non-resonant. In quantum mechanics this leads to meta-stability similar to vacuum decay.

We investigate the dynamics of the fidelity and entanglement entropy for several initial states. Our model is the first explicit example of disordered quantum many-body scarred model.
