Non-Abelian gauge fields play an important role in modern theories of fundamental interactions. Here, we report the realization of non-Abelian adiabatic mixing for solving a general IS problem G (8,7) ...

There is now an intensifying international effort to develop robust propulsion systems for hypersonic and supersonic flight. Such a system would allow flight through our atmosphere at very high speeds ...
