To learn about early and fundamental experimental aspects of the high Tc pseudogap | | Comment: | This article review cover many experimental aspects of the pseudogap (=partial gap in the electronic density of states). After a short introduction, the main topics are Angle Resolved Photoemission (ARPES) Tunneling Spectroscopy, Nuclear Magnetic Resonance (NMR), transport properties specific heat, Raman and Magnetic Neutron Scattering.
The d-wave nature of the pseudogap and the superconducting gap is well shown. The review shows clearly that the pseudogap is not an experimental artefact but a common feature to many high Tc superconductors.
It would be nice to have an actualized version of this review including other experimental methods like Nernst effect (Wang et al, cond-mat/0108242) or Hall effect (Matthey et al, cond-mat/0104328 where it seems that an additional crossover temperature T_n or T` is present between the critical temperature Tc and the pseudogap temperature T*. This should help to clarify the problem of the phase diagram of high Tc cuprates (Is the phase diagram compatible with a quantum critical point? etc). And, maybe, a more extended theoretical section with all major approaches could be included as well.
Note: there is a small mistakes in the text of figure 39. The YBCO oxygen doping should be written O_{6+x} in order to match with figure legends and not O_{7-\delta}. x=0.76 is the correct value for the underdoped regime. |
