Perturbation (astronomy)

  1. Self-gravitating bosonic configurations have a stability limit
    Numerical study of self-gravitating bosonic systems reveals critical thresholds for equilibrium and stability in the nonrelativistic regime, with applications to ultralight dark matter candidates.
  2. TTCF matches time averages for nonequilibrium transport in test systems
    TTCF method computes nonequilibrium transport coefficients from short-time dynamics, offering computational advantages over traditional time-average approaches in linear and nonlinear regimes.
  3. Marine biogeochemical cycles show alternative dynamic regimes
    Explore how marine biogeochemical cycles respond to environmental changes. Research reveals alternative dynamic regimes and nutrient-driven hysteresis in ocean ecosystems under climate perturbations.
