Robustness of the charge-ordered phases in IrTe against photoexcitation
C. Monney, A. Schuler, T. Jaouen +8
We present a time-resolved angle-resolved photoelectron spectroscopy study of IrTe, which undergoes two first-order structural and charge-ordered phase transitions on cooling b…
Comment on `Oxygen vacancy-induced magnetic moment in edge-sharing CuO chains of LiCuO'
R. O. Kuzian, R. Klingeler, W. E. A. Lorenz +23
In a recent work devoted to the magnetism of LiCuO, Shu et al. [New J. Phys. 19 (2017) 023026] have proposed a "simplified" unfrustrated microscopic model that differs…
Charge-orbital-lattice coupling effects in the dd-excitation profile of one dimensional cuprates
J. J. Lee, B. Moritz, W. S. Lee +12
We identify dd-excitations in the quasi-one dimensional compound CaYCuO using resonant inelastic x-ray scattering. By tuning across the Cu L-edge, we observe…
Spin-Orbital Separation in the quasi 1D Mott-insulator Sr2CuO3
J. Schlappa, K. Wohlfeld, K. J. Zhou +13
As an elementary particle the electron carries spin \hbar/2 and charge e. When binding to the atomic nucleus it also acquires an angular momentum quantum number corresponding to th…
Exciton condensation driving the periodic lattice distortion of 1T-TiSe2
C. Monney, C. Battaglia, H. Cercellier +2
We address the lattice instability of 1T-TiSe2 in the framework of the exciton condensate phase. We show that, at low temperature, condensed excitons influence the lattice through…
Dramatic effective mass reduction driven by strong electronic correlations
C. Monney, E. F. Schwier, M. G. Garnier +9
We present angle-resolved photoemission experiments on 1T-TiSe2 at temperatures ranging from 13K to 288K. The data evidence a dramatic renormalization of the conduction band below…
Temperature dependent photoemission on 1T-TiSe2: Interpretation within the exciton condensate phase model
C. Monney, E. F. Schwier, C. Battaglia +9
The charge density wave phase transition of 1T-TiSe2 is studied by angle-resolved photoemission over a wide temperature range. An important chemical potential shift which strongly…
Temperature dependence of the excitonic insulator phase model in 1T-TiSe2
C. Monney, H. Cercellier, F. Clerc +6
Recently, detailed calculations of the excitonic insulator phase model adapted to the case of 1\textit{T}-TiSe have been presented. Through the spectral function theoretical ph…
