Identification of soft modes across the commensurate-to-incommensurate charge density wave transition in 1-TaSe
M. Ruggeri, D. Wolverson, V. Romano +3
1-TaSe is a prototypical charge density wave (CDW) material for which electron-phonon coupling and associated lattice distortion play an important role in driving and stabil…
Optical response of the bulk stabilized mosaic phase in Se doped TaSSe
Xuanbo Feng, Liam Farrar, Charles J. Sayers +3
The layered van der Waals material, TaS features a meta-stable mosaic phase on the verge of a nearly commensurate to commensurate charge density wave transition. This meta-st…
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…
Strong Coupling of Coherent Phonons to Excitons in Semiconducting Monolayer MoTe
Charles J. Sayers, Armando Genco, Chiara Trovatello +8
The coupling of the electron system to lattice vibrations and their time-dependent control and detection provides unique insight into the non-equilibrium physics of semiconductors.…
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…
