Synthetic Magnetic Fields Steer Light on a Chip for Faster Communications

I wish people would stop calling this stuff magnetic. It is not. Maybe it can be mathematically explained using some "pseudomagnetic" but it is fundamentally different, because this effect can't do the same things as a real magnetic field (e.g. Faraday rotation). Which would allow integrated optical isolators in Si, which would be a major breakthrough (and is fundamentally impossible as I understand it).
