Physicists identify key mechanism behind chiral charge density wave in TiSe₂
Illustration of cost density wave (CDW) and periodic lattice distortion (PLD) and their symmetries in 1T-TiSe2. The symmetry of the system as an entire can’t be greater than the intersection of the 2 symmetries. Because of this, the system turns into chiral, though neither CDW nor PLD is chiral by itself.
