New Method Reconstructs Potentials and Initial State in Subdiffusion

Researchers recover the potential in subdiffusion from terminal observations; the simple algorithm converges linearly with FEM and a quasi‑boundary method. getnews.me/new-method-reconstructs-... #subdiffusion #inverseproblem

Finite element method for delayed subdiffusion fractional derivative

A discrete finite element scheme solves subdiffusion with constant delay and a Riemann‑Liouville fractional derivative, providing unconditional stability on graded meshes (r=1 uniform). getnews.me/finite-element-method-fo... #fem #subdiffusion

Fractional diffusion without disorder in two dimensions We analyse how simple local constraints in two dimensions lead a defect to exhibit robust, non-transient, and tunable, subdiffusion. We uncover a rich dynamical phenomenology realised in ice- and dime...

Fractional diffusion without disorder: Local gauge constraints in 2D induce robust, tunable #subdiffusion dynamics. Relevant for platforms like artificial spin ice and quantum simulators aiming to realize discrete link models and emergent #gauge theories:
