This booklet containing 30 articles written via hugely reputed specialists is devoted to okay. Alex Müller at the social gathering of his eightieth birthday. The contributions replicate the key learn components of ok. Alex Müller which he activated in hot temperature superconductivity and part transitions. they're theoretical in addition to experimental ones and concentration often on hot temperature superconductivity. A smaller half offers with ferroelectricity and their functions. additionally during this box there have lately been significant holiday throughs experimentally in addition to theoretically to be able to be addressed through the invited authors.

During the clinical profession of okay. Alex Müller he made significant advances within the realizing of ferroelectricity, which was once his significant learn box. the invention of superconductivity in cuprates for which he bought including J. Georg Bednorz the Nobel Prize in 1987 has now not decreased his curiosity during this zone, yet has enlarged his actions significantly.

11 hole doping Coulomb interaction between electrons must then be taken into account The main effect is to open a dip in the DOS at the Fermi level [14, 15], see Fig. 7. We show that this may explain many observed features of the “pseudo-gap”: its value, anisotropy and variation with doping [15]. The anisotropy is directly related to the anisotropy of the Fermi velocity. The loss of states at the Fermi level explains the decrease of thermodynamic coefficients, such as the magnetic susceptibility, at low temperature (Fig.

2 is not violated. Physically, in the lightly-doped LSCO the peculiar electronic structure dictates that electrons with a large wave number and a large velocity become responsible for the charge transport even when the number of mobile carriers are small, and this causes the mean free path of the carriers to be reasonably long ( ≈ 1 nm ≈ 3a) for a rather short relaxation time of about 5 fs. In the real space picture, the fact that the Fermi arcs are responsible for the charge transport means that only those Bloch waves that travel with the wave number ∼ 4 nm–1 along the four directions diagonal to the Cu – O – Cu bond directions can carry current.
