Unveiling the Semimetallic Nature of 1-TiSe by Doping its Charge Density Wave
T. Jaouen, M. Rumo, B. Hildebrand +10
The semimetallic or semiconducting nature of the transition metal dichalcogenide 1-TiSe remains under debate after many decades mainly due to the fluctuating nature of its 2…
Excitonic Josephson effect in double-layer graphene junctions
B. Zenker, H. Fehske, H. Beck
We show that double-layer graphene (DLG), where an external potential induces an charge-imbalance between - and -type layers, is a promising candidate to realize an exciton c…
Impact of Electron-Hole Correlations on the 1T-TiSe2 Electronic Structure
G. Monney, C. Monney, B. Hildebrand +2
Several experiments have been performed on 1T-TiSe2 in order to identify whether the electronic structure is semimetallic or semiconducting without reaching a consensus. In this pa…
Fate of the excitonic insulator in the presence of phonons
B. Zenker, H. Fehske, H. Beck
The influence of phonons on the formation of the excitonic insulator has hardly been analyzed so far. Recent experiments on , 1-, and $\rm TmSe_{0.45…
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…
