(In-)stability and stabilisation of QNL-type atomistic-to-continuum coupling methods [PDF]

, 2014
We study the stability of ghost force-free energy-based atomistic-to-continuum coupling methods. In 1D we essentially complete the theory by introducing a universally stable a/c coupling as well as a stabilisation mechanism for unstable coupling schemes.
