Multiple mobile excitons manifested as sidebands in quasi-one-dimensional metallic TaSe3

Oleg Yazyev, Christopher Marc Mudry, Daniel Gosalbez Martinez

Charge neutrality and their expected itinerant nature makes excitons potential transmitters of information. However, exciton mobility remains inaccessible to traditional optical experiments that only create and detect excitons with negligible momentum. Her ...

Second-harmonic generation in atomically thin 1T-TiSe2 and its possible origin from charge density wave transitions

László Forró, Helmuth Berger

Optical second-harmonic generation (SHG) can only occur in noncentrosymmetric crystals in the leading electric-dipole approximation. Transition metal dichalcogenides with the 1T octahedral coordination is centrosymmetric, hence precluding SHG. Here we repo ...
