During August 24-27, 1993, approximately 60 scientists from the
Americas, Europe and Japan, gathered in the city of Guanajuato, in
the state of Guanajuato, Mexico, at the II Latin American Workshop
on Magnetism, Magnetic Materials and their Applications. The group
of scientists converging into the beautiful city of Guanajuato had
come from Argentina, Chile, Brazil, Venezuela, Cuba, several places
in Mexico, U. S. A. , Japan, Spain, France, Italy, Germany,
Austria, Switzerland, and Denmark. The event attested to the
success of the previous Workshop on Magnetism, Magnetic Materials
and their Applications, held in Havana, Cuba, in 1991, as well as
to the interest, level of activity and quality of the work being
carried out in Latin America in the area of magnetism and magnetic
materials. Equally important to everyone present was the fact that
we had come to honor a friend, Professor L. M. Falicov, on his
sixtieth birthday. The choice of a Latin American Workshop on
magnetism as a Festschrift for Leo Falicov was, in our opinion,
quite appropriate not only because of Leo's strong ties to Latin
America, but also because of his superb contributions to science,
and in particular, to magnetism. Professor Falicov was born in
Buenos Aires, Argentina, where he spent a good part of his
formative years.
This volume contains the papers presented at the International
Workshop on the Cur rent Problems in Condensed Matter: Theory and
Experiment, held at Cocoyoc, More los, Mexico, during January 5-9,
1997. The participants had come from Argentina, Austria, Chile,
England, France, Germany, Italy, Japan, Mexico, Switzerland, and
the USA. The presentations at the Workshop provided state-of-art
reviews of many of the most important problems, currently under
study, in condensed matter. Equally important to all the
participants in the workshop was the fact that we had come to honor
a friend, Karl Heinz Bennemann, on his sixty-fifth birthday. This
Festschrift is just a small measure of recognition of the
intellectualleadership of Professor Bennemann in the field and
equally important, as a sincere tribute to his qualities as an
exceptional friend, college and mentor. Those who have had the
privilege to work closely with Karl have been deeply touched by
Karl's inquisitive scientific mind as well as by bis kindness and
generosity."
This volume contains the papers presented at the First
Mexico-U.S.A. Symposium on Materials Sciences and Engineering held
in Ixtapa, Guerrero, Mexico, during Septem ber 24-27, 1991. The
conference was conceived with the primary objective of increas ing
the close ties between scientists and engineers in both Mexico and
the U.S. with an interest in materials. The conference itself would
have not taken place without the drive, determination and technical
knowledge of John K. Tien of the University of Texas at Austin and
of Francisco Mejia Lira of the Universidad de San Luis Potosi. This
book is dedicated to their memory. The event brought together
materials scientists and engineers with interests in a broad range
of subjects in the processing, characterization and properties of
advanced materials. Several papers were dedicated to structural
materials ranging from ferrous alloys to intemetallics, ceramics
and composites. The presentation covered properties, processing,
and factors that control their use, such as fatigue and corrosion.
Other materials and properties were also explored by U.S. and
Mexican participants. Sev eral papers dealt with the
characterization and properties of magnetics, optical and
superconductor materials, nanostructured materials, as well as with
computational and theoretical aspects likely to impact future
materials research and development."
This vohune contains the papers presented at the Adriatico Research
Conference on Structural and Phase Stability of Alloys held in
Trieste, Italy, in May 1991, under the auspices of the
International Centre for Theoretical Physics. The conference
brought together participants with a variety of interests in
theoretical and experimental aspects of alloys from Argentina,
Belgium, Bulgaria, Czechslovakia, France, Germany, Italy, Japan,
Mexico, People's Republic of Congo, Portugal, Switzerland, United
Kingdom, United States, U. S. S. R., and Venezuela. The conference
was purposely designed to succinctly cover experimental and the
oretical aspects of magnetic and non-magnetic alloys, surfaces,
thin films and nanos tructures. The Conference opened with an
overview of a select class of advanced structural materials, with a
potential in engineering applications, for which the con ventional
"physics" approach, both theoretical and experimental, should have
a sig nificant impact. A number of papers were dedicated to the use
of phenomenological approaches for the description of thermodynamic
bulk and surface properties. It was clear from these presentations
that the phenomenological models and simulations in alloy theory
have reached a high degree of sophistication. Although with
somewhat limited predictive powers, the phenomenological models
provide a valuable tool for the understanding of a variety of
subtle phenomena such as short-range order, phase stability,
kinetics and the thermodynamics of surfaces and antiphase
boundaries, to name a few."
Oaxaca, Mexico, was the place chosen by a large international group
of scientists to meet and discuss on the recent advances on the
understanding of the physical prop- ties of low dimensional
systems; one of the most active fields of research in condensed
matter in the last years. The International Symposium on the
Physics of Low Dim- sions took place in January 16-20, 2000. The
group of scientists converging into the historical city of Oaxaca,
in the state of the same name, had come from Argentina, Chile,
Venezuela, several places in Mexico, Canada, U. S. A. , England,
France, Italy, Germany, Russia, and Switzerland. The presentations
at the workshop provided sta- of-art reviews of many of the most
important problems, currently under study. Equally important to all
the participants in the workshop was the fact that we had come to
honor a friend, Hans Christoph Siegmann, on his sixty-fifth
birthday. This Festschrift recognizes the intellectual leadership
of Professor Siegmann in the field and as a sincere homage to his
qualities as an exceptional friend, college and mentor. Those who
have had the privilege to work closely with Hans Christoph have
been deeply impressed by his remarkable analytic mind as well as by
his out of range kindness and generosity. Hans Christoph has
contributed to the understanding of the difficult and very
important problem of the magnetic properties of finite systems:
surfaces, thin films, heterostructures.
This volume is a compilation of papers presented at the
International Workshop on the Theory and Applications of the
Cluster Variation and Path Probability Methods, held in the city of
San Juan, Teotihuacan, Mexico, during June 18-22, 1995. The
presentations at the workshop provided a state of the art review of
the fundamental aspects of the CVM and PPM and their application to
a wide range of problems in statistical mechanics and alloy theory.
The volume begins with several articles dealing with the study of
the kinetics of ordering in Ising sytems and alloys using the PPM
and other classical techniques. These articles are followed by the
contribution of Professor Masuo Suzuki on the Coherent Anomaly
Method which has added a new dimension to mean field theory, and
the CVM in particular, in the study of critical phenomena. The
remaining of the volume is dedicated to fundamental aspects and
specific applications of the CVM in a wide range of subjects
ranging from bulk and surface studies to new areas of inquiry such
as the problem of image reconstruction. Since the inception by
Prof. Ryoichi Kikuchi of the CVM in 1950 and of the PPM in 1966,
the latter after a gestation period of approximately six years, the
tech niques have found wide acceptance in the physics and materials
science communities. Both methods are properly regarded as seminal
contributions to equilibrium and non equilibrium statistical
mechanics."
The papers in this book represent the proceedings for the
International Conference on Oxygen Disorder Effects in High~Tc
Superconductors, held April 18-21, 1989 at the International Centre
for Theoretical Physics, Trieste, Italy. It was recognized very
early in the field of ceramic superconductors that oxygen plays a
crucial role as far as the physical properties of these ma terials
are concerned. The preparation requires special heating and cooling
cycles which allow proper uptake of oxygen, relationships were
found between the oxygen concentration and the superconducting
transition temperature in many of the compounds and quite recently
it was recognized that many (if not all) of the compounds present
oxygen ordering in the intercalating planes. Moreover, it seems
that the presence of superconductivity is strongly correlated with
the presence of orthorhombic phases although several groups have
also claimed the presence of superconductivity in tetragonal
phases. Whether oxygen ordering plays or not a crucial role for the
superconductivity remains to be seen. However it is clear that the
ordering of oxygens and their thermodynamic properties is an
interesting subject on its own right. All these reasons led us to
organize a Conference on Oxygen Disorder Effects in High-Tc
Superconductors in attempt to identify unsolved problems and to
have an open discussion of the presently known facts.
