We introduce a framework for engineering active quantum matter that involves mimicking the role of self-propulsion through an external trapping potential that is moving along imposed trajectories traced by classical active dynamics. This approach in the presence of dissipation, not only recovers essential dynamical behavior of classical activity, including the ballistic to diffusive cross-over of its mean-square displacement, but also reveals additional features of activity that are of quantum origin. These quantum-active features are revealed in non-dissipative systems, and manifest as novel exponents of the mean-square displacement at short timescales.

  1. Gigantic dynamical spreading and anomalous diffusion of jerky active particles

    cond-mat.soft 2025-07 conditional novelty 6.0 of 10

    A linear third-order 'jerk' equation driven by active Ornstein-Uhlenbeck noise yields mean-square displacement scaling with time exponents 6, 5, 4, or 3, and can destabilize harmonic confinement.

  2. What exactly is 'active matter'?

    cond-mat.soft 2025-07 accept novelty 4.0 of 10

    Active matter has no unique definition; 'active' depends on a chosen coarse-grained viewpoint, making it a family resemblance term rather than a sharp category.
