Authored by many of the world's leading experts on high-Tc
superconductivity, this volume presents a panorama of ongoing
research in the field, as well as insights into related
multifunctional materials. The contributions cover many different
and complementary aspects of the physics and materials challenges,
with an emphasis on superconducting materials that have emerged
since the discovery of the cuprate superconductors, for example
pnictides, MgB2, H2S and other hydrides. Special attention is also
paid to interface superconductivity. In addition to
superconductors, the volume also addresses materials related to
polar and multifunctional ground states, another class of materials
that owes its discovery to Prof. Muller's ground-breaking research
on SrTiO3.
This book is a collection of the papers presented at the workshop
on "Symmetry and Heterogeneity in High Tc Superconductors" directed
by Antonio Bianconi and Alexander F. Andreev in collaboration with
K. Alex Muller and Giorgio Benedek. Philip B. Allen, Neil W.
Ashcroft, Alan R. Bishop, J. C. Seamus Davis, Takeshi Egami,
Francesco Iachello, David Pines, Shin-ichi Uchida, Subodh R.
Shenoy, chaired hot sessione contributing to the success of the
workshop. The object of the workshop was the quantum mechanism that
allows the macroscopic quantum coherence of a superconducting
condensate to resist to the attacks of high temperature. Solution
to this problem of fundamental physics is needed for the design of
room temperature superconductors, for controlling the decoherence
effects in the quantum computers and for the understanding of a
possible role of quantum coherence in living matter that is debated
today in quantum biophysics. The discussions in the informal and
friendly atmosphere of Erice was on new experimental data showing
that high T in doped cuprate perovskites is c related with the
nanoscale phase separation and the two component scenario, the
two-band superconductivity in magnesium diboride and the lower
symmetry in the superconducting elements at high pressure."
This book is a collection of papers in the field of stripes and
high Tc superconductivity. The most relevant theoretical and
experimental contributions from experts in the field of stripes,
presented at the Second International Conference on Stripes and
High Tc Superconductivity, are selected for publication. The book
includes contributions on other stripe phases observed in
manganites, nikelates, spin ladders, and heterostructures. Since a
large stream of research in a growing community is converging
towards the stripe scenario, this book serves as an important
reference in the field of striped phases and high Tc
superconductivity. The problem of high Tc superconductors has been
a central issue in solid-state physics since 1987. After the
discovery of high Tc superconductivity (HTSC) in doped perovskites,
it was realized that HTSC appears in an unknown complex electronic
phase of condensed matter. In the early years, all theories of HTSC
were focused on the physics of a homogeneous 2D metal with large
electron-electron correlations or on a 2D polaron gas. Only after
1990 a novel paradigm started to emerge in which this 2D metallic
phase is described as an inhomogeneous metal. This was the outcome
of several experimental evidences of phase separation at low
doping. Following the discovery by the Rome Group in 1992 that the
changes move freely mainly in one direction like the water running
in the grooves in corrugated iron foil', a new scenario for
understanding superconductivity in high Tc superconductors was
opened. Since the charges move like rivers, the physics of these
materials shifts towards the physics of novel mesoscopic
heterostructures and complex electronic solids. Therefore,
understanding the striped phases in the perovskites not only
provides an opportunity to understand the anomalous metallic state
of cuprate superconductors, but also suggests a way to design new
materials of technological importance. The stripes are begetting a
field of general scientific interest.

This book the second volume in the "Springer Series in Biophysics"
col lects together contributions to the conference on "Biophysics
and Syn chrotron Radiation" held in July 86 at Frascati. This
meeting addressed the advances on the structure of biological
molecules obtained by using synchrotron radiation. In fact it was
most timely to review the results of the research in biophysics
which is rapidly developing at synchrotron radiation facilities.
Moreover, there was interest to discuss the new perspectives opened
up by the future high brilliance synchrotron radia tion sources.
With the use of synchrotron radiation, x-ray spectroscopy of
biological molecules is firmly established in the techniques of
EXAFS and XANES. Contributions to the detailed knowledge of local
structure of active sites of metalloproteins by this approach are
presented in this volume, together with a number of studies of -the
interaction of metal ions with other important biological
macromolecular systems. Structural determination of very large
biological systems at high reso lution, including a protein and its
substrate, are reported. The experi mental advances in protein
crystallography presented here reduce the time for solving protein
structures, thus satisfying a major require ment of the
rapidly-expanding field of protein engineering."
