Scalar Truesdell Time Derivative and -- Surface Gradient Flows
Rainer Backofen, Ingo Nitschke, Axel Voigt
We address surface gradient flows which allow for energy dissipation by evolving the surface and a scalar quantity on it, simultaneously. A proper choice of the time derivative and…
Self-organized flows break morphological symmetry in active/passive systems
Rainer Backofen, Axel Voigt
We consider a phase-separating mixture of active and passive fluids and explore morphological asymmetries of the emerging dominantly bicontinous dynamic emulsion. Two-dimensional n…
Nonequilibrium hyperuniform states in active turbulence
Rainer Backofen, Abdelrahman Y. A. Altawil, Marco Salvalaglio +1
We demonstrate that the complex spatiotemporal structure in active fluids can feature characteristics of hyperuniformity. Using a hydrodynamic model, we show that the transition fr…
Magnetically enhanced thin film coarsening by a magnetic XPFC model allowing to decouple magnetic anisotropy and magnetostriction
Rainer Backofen, Axel Voigt
External magnetic fields provide a macroscopic control mechanism to influence the microstructure of polycrystalline materials. We model the influence of strong magnetic fields on g…
Controlling magnetic anisotropy in amplitude expansion of phase field crystal model
Rainer Backofen, Marco Salvalaglio, Axel Voigt
The amplitude expansion for a magnetic phase-field-crystal (magnetic APFC) model enables a convenient coarse-grained description of crystalline structures under the influence of ma…
Magnetic APFC modeling and the influence of magneto-structural interactions on grain shrinkage
Rainer Backofen, Marco Salvalaglio, Axel Voigt
We derive the amplitude expansion for a phase-field-crystal (APFC) model that captures the basic physics of magneto-structural interactions. The symmetry breaking due to magnetizat…
