• Title: On the testability of the K\'arolyh\'azy model
• Abstract summary: K'arolyh'azy's original proposal, suggesting that space-time fluctuations could be a source of decoherence in space, faced a significant challenge due to an unexpectedly high emission of radiation. We reevaluated K'arolyh'azy's assumption that the metric fluctuation must adhere to a wave equation.

• Abstract: K\'arolyh\'azy's original proposal, suggesting that space-time fluctuations could be a source of decoherence in space, faced a significant challenge due to an unexpectedly high emission of radiation (13 orders of magnitude more than what was observed in the latest experiment). To address this issue, we reevaluated K\'arolyh\'azy's assumption that the stochastic metric fluctuation must adhere to a wave equation. By considering more general correlation functions of space-time fluctuations, we resolve the problem and consequently revive the aforementioned proposal.

  We use a braiding nonequilibrium fluctuation dissipation relation linking the DC noise to the response function inferred from the braiding constraint in the time-domain.<n>This questions the universality of $theta$ that can reflect the microscopic edge dynamics, in contrast to the topologically protected braiding phase in the space domain.

• Closed-form solutions for the Salpeter equation [41.94295877935867]
  We study the propagator of the $1+1$ dimensional Salpeter Hamiltonian, describing a relativistic quantum particle with no spin. The analytical extension of the Hamiltonian in the complex plane allows us to formulate the equivalent problem, namely the B"aumer equation. This B"aumera corresponds to the Green function of a relativistic diffusion process that interpolates between Cauchy for small times and Gaussian diffusion for large times.

• Problems with Modified Commutators [0.0]
  We show how an apparently simple assumption can generate generalised uncertainty relations without modifying the basic form of the canonical Heisenberg algebra. This assumption has huge implications for the quantisation of space-time and, therefore, gravity. We argue that these proposals should be taken seriously, as a potential solution to the pathologies that plague minimum length models based on modified commutators.

  We study the structure of quantum control landscape for the problem of single-qubit phase shift gate generation on the fast time scale. A special critical point which was known to exist in quantum control landscapes was shown to be either a saddle or a global extremum. In this work, we compute the numbers of negative and positive eigenvalues of Hessian at this saddle point and moreover, give estimates on magnitude of these eigenvalues.

  The eigenstate thermalization hypothesis (ETH) offers a universal mechanism for the approach to equilibrium of closed quantum many-body systems. Here, we propose a theory-independent route to probe the full ETH in quantum simulators by observing the emergence of fluctuation-dissipation relations. Our work presents a theory-independent way to characterize thermalization in quantum simulators and paves the way to quantum simulate condensed matter pump-probe experiments.
