Spontaneous exciton condensation in 1T-TiSe2: a BCS-like approach
C. Monney, H. Cercellier, F. Clerc +9
Recently strong evidence has been found in favor of a BCS-like condensation of excitons in 1\textit{T}-TiSe. Theoretical photoemission intensity maps have been generated by the…

Evidence for an excitonic insulator phase in 1T-TiSe
H. Cercellier, C. Monney, F. Clerc +7
We present a new high-resolution angle-resolved photoemission study of 1\textit{T}-TiSe in both, its room-temperature, normal phase and its low-temperature, charge-density wa…

Direct evidence for ferroelectric polar distortion in ultrathin lead titanate perovskite films
L. Despont, C. Lichtensteiger, C. Koitzsch +7
X-ray photoelectron diffraction is used to directly probe the intra-cell polar atomic distortion and tetragonality associated with ferroelectricity in ultrathin epitaxial PbTiO3 fi…
