An intensive exchange of ideas between related fields of theoretical physics allows for a rapid spreading of new concepts and of new methods among different research directions. This should be particularly true for the topics chosen for the planned workshop on Correlations and Coherence in Quantum Matter: quantum-many-body theory, statistical mechanics, quantum field theory and quantum computation. This workshop will provide an excellent setting for the promotion of this cross-fertilization, through a well-balanced menu of talks by leading experts, through lively poster sessions and through numerous informal discussions. The past experience of the organizers has amply proven that the city of Évora offers a unique environment for this kind of workshop.
Special attention will be given to recent advances in the fractional quantum Hall effect, quantum phase transitions, magnetic chains and ladders, atomic gases on optical lattices with reduced dimensions, quantum computation (for instance the topological protection of quantum bits), the many facets of graphene (such as the minimal conductivity, the anomalous quantum Hall effect, or the connection to special relativity and gravity), metal-insulator transitions, spin liquids, fractional charge and statistics, and transport through quantum dots. Both analytical and numerical methods will be discussed, for instance exact solutions by the Bethe Ansatz (which now allows for the calculation of correlation functions), bosonization, techniques of conformal field theory, new approaches for treating non-equilibrium phenomena, the use of gauge fields to take into account certain constraints, the (numerical) Density Matrix Renormalization Group, and matrix product states that allow to formulate promising variational many-body wave functions.
