Crtical Current by Design Through Large-scale Simulations

Understanding the dynamic behavior of vortex matter in complicated pinning landscapes is a major challenge for both fundamental science and energy applications. In particular, optimizing type, size and density of pinning centers can significantly enhance the critical current. Based on the time-dependent Ginzburg-Landau equation, we developed a numerical approach towards finding these optimal pinning configurations. I will give an overview of this new paradigm, called Critical Current by Design.\\ {\it References:}\\ $\left[1\right]$ I. A. Sadovskyy, A. E. Koshelev, C. L. Phillips, D. A. Karpeev, A.
