Research activities
Key fields: Electronic structure (all), Superconductivity (2,4,5,6,7,8,9), Phonons and electron-phonon coupling
(2,4,6,7,12), Magnetism and magnetic properties (3,8,11), Transport properties (3), Excited and correlated states
(9,10,13), Interpretation of experiments (5,8,12).
1. Theoretical study (analytical and numerical) of non-adiabatic corrections in the case of two coupled harmonic oscillators [1]. This is a case-study in which the Born-Oppenheimer expansion in the small factor ε2 =
(m/M)½ of the wave function (see for instance G. A. Hagedorn, Commun. Math. Phys. 117, 387 (1988)) can be
compared with the exact solution of the time-dependent Shrödinger equation (Diploma work, EPFL) [1].
2. Solution of the Eliashberg equations for various models of k-dependent electron-phonon coupling, in order
to simulate the situation in high-Tc superconductors [2-5, 7, 12]. In particular, we considered the case of
“forward scattering” coupling which favours attractive coupling only between electrons close to one another on
the Fermi surface. We showed that such an isotropic electron-phonon coupling leads to a d-wave superconducting order parameter [5].
3. Electronic structure, magnetic and transport properties of magnetic perovskite oxides (ruthenates and
manganites) and of some Ce-based magnetic materials [6,8,9,12,16,19]. For the ruthenates, we calculated the
electronic structure of SrRuO3 and CaRuO3. The question here is to understand why the first compound is ferromagnetic whereas the second exhibits no long range order. We found that the chemical pressure (contraction of
the lattice when substituting with Ca) seems to be responsible for the destruction of ferromagnetism [8]. In the
case of the manganites, we studied (Nd,La,Ca,Sr)MnO 3 compounds, using both the virtual crystal approximation
(VCA) and supercells when possible. The calculated Fermi surface was in good agreement with experiment [16,
19]. From our calculations, the colossal magnetoresistance phenomena could be explained in term of a metalinsulator transition accompanying a magnetic one through a change in the underlying electronic structure [9,12].
The study of CeRu2Ge2 (the "non-heavy fermion cousin of CeCu2Si2") showed that the difference in total energies between different magnetic configurations for various pressures was extremely small, accounting for the interesting magnetic phase diagram of this compound at low temperature [12].
4. Computation of the electron-phonon coupling in high-Tc superconductors from the electronic structure.
Anisotropic coupling and effect of temperature [7,10,12,13,15,17]. Our study of the effect of the atomic displacements on the electronic structure of some high-Tc superconductors (Hg-1201, Bi-2212 and Y-123) showed
a surprisingly large sensitivity to the amplitude of displacement. In the case of Hg-1201, we showed that this
leads to a decrease of the c-axis resistivity with temperature as observed generally in cuprates. For Hg-1201, we
also computed the k-dependent electron-phonon coupling function g(k, k’) for different k on the Fermi surface.
We found that the coupling has indeed a strong “forward scattering” component. The corresponding solution of
the Eliashberg equations was found to have a d-wave like symmetry [12].
5. Calculation of momentum densities [11, 14, 16, 19, 27]. Some experimental techniques (such as positron annihilation or Compton scattering) are directly sensitive to the momentum density. Therefore, in order to use these
techniques as probes of the electronic structure, the momentum density has to be computed from first-principles
calculations for comparison. This has been used to clarify the previous discrepancy between experiment and theory in the case of Cr and Mo as well as to compare the results for the borocarbide LuNi 2B2C. This material
shows an interesting interplay between magnetism and superconductivity and our study has put forward nesting
features of the Fermi surface that could be of importance for the understanding of its magnetic and superconducting properties. It has also been used to investigate the spin-polarisation in the manganites and the charge density
wave in tritellurides.
6. Electron-phonon interaction in hcp Xe under pressure. Under pressure, Xe displays interesting properties
such as a structural transition between fcc and hcp around 90 GPa and an insulator-metal transition around

140 GPa. We calculated the phonon spectra (using the inter-atomic force method we have developed) for different pressures around the insulator-metal transition and the electron-phonon coupling from first-principles. From
our calculated electron-phonon coupling constant of  = 0.61, we predict that Xe should undergo a superconducting transition around 150 GPa with a Tc of a few degrees. [21]
Ab initio electronic structure and phonon spectrum of MgB 2. Using the inter-atomic force method we have
developed for Xe, we calculated the phonon spectrum for the newly discovered “high-Tc” superconductor MgB2.
We found that the E2g mode (the optical stretching of the Boron hexagon) is strongly non-linear. This nonlinearity has been claimed to be of importance for the superconducting properties in hardening the phonon mode
and reducing the transition temperature [20].
Magnetic and superconducting properties of ZrZn2 [18, 22, 23]. The coexistence of ferromagnetism and superconductivity recently discovered in d-electron compound ZrZn2 has raised the question of the pairing mechanism in this material. We have calculated the generalised susceptibility, as well as the electron-phonon coupling
from ab initio electronic structure calculations and found that the longitudinal spin-fluctuations are predominant
and can lead to p-wave spin-triplet superconductivity. I have also developed a code to obtain all the extremal orbits from the calculation, allowing a direct comparison with de Haas-van Alphen experimental results [22], as
well as participated in the development of the one allowing the extraction of the Fermi surface from positron annihilation measurements [23].
Superconductivity in PuCoGa5. The recent discovery of superconductivity above 18 K makes it the highest-Tc
f-electron material by an order of magnitude. I am currently calculating the electronic structure properties, the
magnetic susceptibility as well as the electron-phonon coupling in order to elucidate the origin of this high- Tc.
Physics of f-electron systems from ab initio calculations [24,25,29]. f-electron materials are notoriously badly
described by the standard approximations used in DFT. The localisation/delocalisation and mixed-valency problems are of particular interest. Self-interaction corrected (SIC) ab initio total energy calculations of Sm and Eu
pnictides and chalcogenides have shown that the general trends (in lattice parameters and localisation) can be accounted for [24,25]. This approach is being extended to other lanthanides, together with the so-called "HubbardI" approximation to describe the multiplet states and reproduce the observed photoemission spectra.
Non-collinear magnetism [26]. Peculiar magnetic behaviours and the mechanism behind them still constitute an
interesting and mostly unsolved problem. Among those, we focused on the appearance of weak ferromagnetism
in some “almost antiferromagnetic materials” caused by the breakdown of the compensation of the large local
magnetic moments. Our first-principles study of Mn3Sn shows that it is the non-collinearity of the magnetisation
density on non-magnetic atoms, and not the spin-orbit coupling as suggested previously, that plays the key role
leading to weak ferromagnetism.
Anharmonic vibrational properties of the clathrate thermoelectrics [30]. Clathrates are very promising thermoelectric materials owing to their large “figure of merit”. They illustrate the “Phonon Glass - Electronic Crystal” concept leading to the required low thermal conductivity. We have undertaken an ab initio study of the anharmonicity of the rattler modes as well as of the calculation of the resulting neutron scattering spectra to allow
for a direct comparison. The frequencies are in excellent agreement with the position of the experimental peaks.
Optical and excitonic properties [28]. The optical and excitonic properties of wurzite GaN have been calculated from first-principles by solving the Bethe-Salpeter equation. The binding energies and absorption spectra are
found to be in good agreement with experiment.
