'Scientists at the University of California, Berkeley and Lawrence Berkeley National Laboratory (also in Berkeley) have experimentally discovered that a so-called Weyl semimetal, tantalum arsenide (TaAs), has the largest nonlinear optical response of any known crystal, achieving second-harmonic generation (SHG) of light with unprecedented response." by John Wallace
