Charge transport systems with Fermi-Dirac statistics for memristors
Maxime Herda, Ansgar Jüngel, Stefan Portisch
An instationary drift-diffusion system for the electron, hole, and oxygen vacancy densities, coupled to the Poisson equation for the electric potential, is analyzed in a bounded do…
Bayesian inversion for the identification of the doping profile in unipolar semiconductor devices
Leila Taghizadeh, Ansgar Jüngel
A rigorous Bayesian formulation of the inverse doping profile problem in infinite dimensions for a stationary linearized unipolar drift-diffusion model for semiconductor devices is…
Global weak solutions to a fractional Cahn-Hilliard cross-diffusion system in lymphangiogenesis
Ansgar Jüngel, Yue Li
A spectral-fractional Cahn-Hilliard cross-diffusion system, which describes the pre-patterning of lymphatic vessel morphology in collagen gels, is studied. The model consists of tw…
Structure-preserving Local Discontinuous Galerkin method for nonlinear cross-diffusion systems
Sergio Gómez, Ansgar Jüngel, Ilaria Perugia
We present and analyze a structure-preserving method for the approximation of solutions to nonlinear cross-diffusion systems, which combines a Local Discontinuous Galerkin spatial…
Fluctuations around the mean-field limit for attractive Riesz potentials in the moderate regime
Li Chen, Alexandra Holzinger, Ansgar Jüngel
A central limit theorem is shown for moderately interacting particles in the whole space. The interaction potential approximates singular attractive or repulsive potentials of sub-…
Long-time behavior for discretization schemes of Fokker-Planck equations via couplings
Ansgar Jüngel, Katharina Schuh
Continuous-time Markov chains associated to finite-volume discretization schemes of Fokker-Planck equations are constructed. Sufficient conditions under which quantitative exponent…
