Camiel van Efferen,Jan Berges,Joshua Hall,Erik G. C. P. van Loon,Stefan Kraus,Arne Schobert,Tobias Wekking,Felix Huttmann,Eline Plaar,Nico Rothenbach,Katharina Ollefs,Lucas M. Arruda,N. B. Brookes,Gunnar Schönhoff,Kurt Kummer,Heiko Wende,Tim O. Wehling,Tim O. Wehling,Thomas Michely +18 more
TL;DR: In this paper, the authors showed that the non-linear coupling of transverse and longitudinal phonons is essential for the formation of the charge density wave (CDW) and the full gap above the Fermi level.

Divita Gupta,Weslley G. D. P. Silva,José Luis Doménech,Eline Plaar,Sven Thorwirth,Stephan Schlemmer,Oskar Asvany +6 more
TL;DR: In this article , the authors applied a novel action spectroscopic technique in a 4 K cryogenic ion-trap instrument for high-resolution rovibrational and pure rotational spectroscopy for the first time.
High-resolution spectroscopy of the ν3 antisymmetric C–H stretch of C2H2+ using leak-out action spectroscopy

Camiel van Efferen,Jan Berges,Joshua Hall,Erik G. C. P. van Loon,Stefan Kraus,Arne Schobert,Tobias Wekking,Felix Huttmann,Eline Plaar,Nico Rothenbach,Katharina Ollefs,Lucas M. Arruda,N. B. Brookes,Gunnar Schoenhoff,Kurt Kummer,Heiko Wende,Tim O. Wehling,Thomas Michely +17 more
TL;DR: In this article, the authors present experimental evidence of a full charge density wave gap residing in the unoccupied states of monolayer VS2, and show that anharmonic coupling of transverse and longitudinal phonons is essential for the formation of the gap.
