Accelerated methods improve nonlinear fractional diffusion solving
What the study found The study proposes an efficient and accurate framework for nonlinear space-time fractional diffusion equations. The authors report that the resulting spectral deferred correction method keeps arbitrary order accuracy and excellent stability. Why the authors say this matters The authors state that the method is efficient and accurate, and they present a…
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.
Nonlocal media support dark, antidark, and mixed soliton pairs
Researchers identify two families of vector soliton pairs in nonlocal nonlinear systems, including novel mixed-polarity solutions with symmetry-breaking structure.
