Change in charge density wave order beyond the Lifshitz transition in 2H-Ta\textsubscript{1}S\textsubscript{2}

Mihir Date, Jan Berges, Enrico Da Como +6

We investigate electronic instabilities in 2H-TaS\textsubscript{2} and a self-intercalated variant, 2H-Ta\textsubscript{1+}S\textsubscript{2}. In conventional samples,…

Lifshitz transition enabling superconducting dome around the quantum critical point in TiSe

R. D. H. Hinlopen, Owen Moulding, Will Broad +9

Superconductivity often emerges as a dome around a quantum critical point (QCP) where long-range order is suppressed to zero temperature. So far, this has been mostly studied in ma…

Exploring the Charge Density Wave phase of 1-TaSe: Mott or Charge-transfer Gap?

C. J. Sayers, G. Cerullo, Y. Zhang +8

1-TaSe is widely believed to host a Mott metal-insulator transition in the charge density wave (CDW) phase according to the spectroscopic observation of a band gap that exte…

Spectrally resolving the phase and amplitude of coherent phonons in the charge density wave state of 1-TaSe

Charles J. Sayers, Stefano Dal Conte, Daniel Wolverson +4

The excitation and detection of coherent phonons has given unique insights into condensed matter, in particular for materials with strong electron-phonon coupling. We report a stud…

Observation of the charge density wave collective mode in the infrared optical response of VSe

Xuanbo Feng, Jans Henke, Corentin Morice +4

We present a detailed study of the bulk electronic structure of high quality VSe single crystals using optical spectroscopy. Upon entering the charge density wave phase below…

Investigation of the Non-equilibrium State of Strongly Correlated Materials by Complementary Ultrafast Spectroscopy Techniques

Hamoon Hedayat, Charles J. Sayers, Arianna Ceraso +6

Photoinduced non-thermal phase transitions are new paradigms of exotic non-equilibrium physics of strongly correlated materials. An ultrashort optical pulse can drive the system to…
