* * * * * IV Condensed Matter Workshop (ENFISOL IV) * * * * *
 
 This is the fourth version of the bi-anual series of Condensed Matter
Workshops (Encuentros de Fisica del Solido) that take place around
New Year's day in Santiago, Chile. Their purpose is to promote
work and collaboration in the basics of this very rich field.
The meeting is sponsored by the Chilean Society of Physics.
 
The main international meeting will take place January 3-7, 1994.
In order to enhance the opportunity for fruitfull collaborations
the total length of the Workshop will be three weeks, December 27-
January 14, 1994, and visitors will be encouraged to stay as long
as possible within these three weeks. Please make your plane reser-
vations early since around the turn of the year airlines tend to
be overcrowded.
                
As in previous versions of this Workshop series (I-III), the
meeting will take place in the main library of the San Joaquin
Campus of the Catholic University, Santiago (Vicuna Mackenna 4860).
A medium- (air conditioned) and large- size conference rooms
have been reserved, together with three seminar rooms and a
number of individual offices. The excellent library collections
will be open to participants.
 
Program:
 
In keeping with tradition the program will be rather broad.
The first week there will be introductory minicourses for graduate
students. The aim of these sessions is to expose students with a
broad background, to fields of current interest in Condensed Matter
Physics. In the second week (January 3-7) a special Symposium on
Incommensurate Matter will be held. Invited talks will be concentrated
in this week. The third week is left free of formal programming, and
it has been set to enhance the opportunity for collaboration.
