• Authors: Mat\'ias Manti\~nan, Francisco D. Mazzitelli and Leonardo G. Trombetta
• Abstract summary: We study a random version of the dynamical Casimir effect, computing the particle creation inside a cavity produced by a motion of one of its walls. In the single-mode, the equations are formally analogous to those that describe the particle creation in a cosmological context, that we rederive using multiple scale analysis.

• Abstract: We study a stochastic version of the dynamical Casimir effect, computing the particle creation inside a cavity produced by a random motion of one of its walls. We first present a calculation perturbative in the amplitude of the motion. We compare the stochastic particle creation with the deterministic counterpart. Then we go beyond the perturbative evaluation using a stochastic version of the multiple scale analysis, that takes into account stochastic parametric resonance. We stress the relevance of the coupling between the different modes induced by the stochastic motion. In the single-mode approximation, the equations are formally analogous to those that describe the stochastic particle creation in a cosmological context, that we rederive using multiple scale analysis.

  We develop an artificial intelligence framework which combines a neural network trained to mimic simulated data from a model Hamiltonian with automatic differentiation to recover unknown parameters from experimental data. In doing so, we illustrate the ability to build and train a differentiable model only once, which then can be applied in real-time to multi-dimensional scattering data.

  We formulate a model of a quantum particle continuously monitored by detectors measuring simultaneously its position and momentum. For sparsely distributed detectors, we use methods from renewal theory of processes to obtain some semi-analytic results. For a semi-continuous spatial distribution of meters the emergence of classical trajectories is shown.

  Unavoidable coupling of quantum systems to external degrees of freedom leads to dissipative (non-unitary) dynamics. We introduce a method to deal with these systems based on the calculation of (dissipative) lattice Green's function. We illustrate the power of this method with several examples of driven-dissipative bosonic chains of increasing complexity.

  We show that the system dynamics under random dynamical decoupling converges to a unitary with a decoupling error that characteristically depends on the convergence speed of the Zeno limit. This reveals a unification of the random dynamical decoupling and the quantum Zeno effect.

  We study a (relativistic) Wiener process on a complexified (pseudo-)Riemannian manifold. If the process has a purely real variation, we obtain the one-sided Wiener process encountered in the theory of Brownian motion. For a purely imaginary quadratic variation, we obtain a description of a quantum particle on a curved spacetime.

• Generative Ensemble Regression: Learning Particle Dynamics from Observations of Ensembles with Physics-Informed Deep Generative Models [27.623119767592385]
  We propose a new method for inferring the governing ordinary differential equations (SODEs) by observing particle ensembles at discrete and sparse time instants. Particle coordinates at a single time instant, possibly noisy or truncated, are recorded in each snapshot but are unpaired across the snapshots. By training a physics-informed generative model that generates "fake" sample paths, we aim to fit the observed particle ensemble distributions with a curve in the probability measure space.
