14 p, 7.0 MB Fermi surface electron-hole instability of the (TMTSF)2PF6 Bechgaard salt revealed by the first-principles Lindhard response function / Guster, Bogdan (Institut Català de Nanociència i Nanotecnologia) ; Pruneda, Miguel (Institut Català de Nanociència i Nanotecnologia) ; Ordejon, Pablo (Institut Català de Nanociència i Nanotecnologia) ; Canadell Casanova, Enric 1950- (Institut de Ciència de Materials de Barcelona) ; Pouget, Jean-Paul (Laboratoire de Physique des Solides CNRS)
We report the first-principles DFT calculation of the electron-hole Lindhard response function of the (TMTSF)PF Bechgaard salt using the real triclinic low-temperature structure. The Lindhard response is found to change considerably with temperature. [...]

(CIC NanoGUNE) ; Ordejon, Pablo (Institut Català de Nanociència i Nanotecnologia) ; Canadell Casanova, Enric 1950- (Institut de Ciència de Materials de Barcelona)
Bulk and single-layer 2H-NbSe₂ exhibit identical charge density wave order (CDW) with a quasi-commensurate 3 × 3 superlattice periodicity. Here we combine scanning tunnelling microscopy (STM) imaging at T = 1 K of 2H-NbSe₂ with first-principles density functional theory (DFT) calculations to investigate the structural atomic rearrangement of this CDW phase.

8 p, 3.1 MB 2 × 2 charge density wave in single-layer TiTe₂ / Guster, Bogdan (Institut Català de Nanociència i Nanotecnologia) ; Robles, Roberto (Institut Català de Nanociència i Nanotecnologia) ; Pruneda, Miguel (Institut Català de Nanociència i Nanotecnologia) ; Canadell Casanova, Enric 1950- (Institut de Ciència de Materials de Barcelona) ; Ordejon, Pablo (Institut Català de Nanociència i Nanotecnologia)
A density functional theory study concerning the origin of the recently reported 2 × 2 charge density wave (CDW) instability in single-layer TiTe₂ is reported. It is shown that, whereas calculations employing the semi-local functional PBE favor the undistorted structure, the hybrid functional HSE06 correctly predicts a 2 × 2 distortion. [...]

15 p, 6.3 MB Evidence for the weak coupling scenario of the Peierls transition in the blue bronze / Guster, Bogdan (Institut Català de Nanociència i Nanotecnologia) ; Pruneda, Miguel (Institut Català de Nanociència i Nanotecnologia) ; Ordejon, Pablo (Institut Català de Nanociència i Nanotecnologia) ; Canadell Casanova, Enric 1950- (Institut de Ciència de Materials de Barcelona) ; Pouget, Jean-Paul (Université Paris-Sud. Laboratoire de Physique des Solides)
On the basis of first-principles DFT calculations the wave-vector and temperature dependencies of the Lindhard response function of the blue bronze K₀. ₃MoO₃ have been calculated. The kFI+kFII interband component of the response, which is responsible for the Peierls instability, has been quantitatively analyzed. [...]

13 p, 1.2 MB First principles analysis of the CDW instability of single-layer 1T-TiSe2 and its evolution with charge carrier density / Guster, Bogdan (Institut Català de Nanociència i Nanotecnologia) ; Canadell Casanova, Enric 1950- (Institut de Ciència de Materials de Barcelona) ; Pruneda, Miguel (Institut Català de Nanociència i Nanotecnologia) ; Ordejon, Pablo (Institut Català de Nanociència i Nanotecnologia)
We present a density functional theory study of the electronic structure of single-layer TiSe, and focus on the charge density wave (CDW) instability present on this 2D material. We explain the periodicity of the CDW from the phonon band structure of the undistorted crystal, which is unstable under one of the phonon modes at the M point. [...]
