The Scope

The coming Karpacz Winter School is planned to be a genuine school, that is most of the lectures will be organized into coherent series (without substantial overlap) of about six talks of 45 minutes per topic (6-7 main topics). The lectures will provide a basis for discussions of current scientific issues in condensed matter physics, particularly in various systems of electrons. Besides scientific objectives, special emphasis will be put on transfer of knowledge to PhD students and young postdocs. A number of modern promising research directions in condensed matter physics will be presented to participants.

Main Topics

 Dynamical Mean Field Theory
 Density Functional  Method
 Spintronics
 Carbon Nanostructures (fullerens, nanotubes, graphen)
 Quantum Spin Systems
 2D electron gas, quantum Hall effect
 Quantum dots

Krzysztof Byczuk (Augsburg, Germany)
Dynamical mean-field theory for correlated and disordered electrons
 
Summary
The dynamical mean-field theory is a mathematical method to investigate electrons on a lattice in the presence of local interactions and/or local disorder. It is an exact solution of corresponding problems in the infinite dimension (coordination number). In the case of finite dimensional systems it can be used as an approximate but controlled solution. The mean-field theory is particularly useful whenever local time-dependent correlations determine the physics and space correlations can be omitted or treated later by a perturbation theory. In the present set of lectures I will: 1. present general introduction into the dynamical mean-field theory; 2. present explicit derivation of the mean-field equations and discuss how to solve them; 3. present selected intermediate coupling problems, which were solved rigorously by the dynamical mean-field theory; 4. present the application of the dynamical mean-field theory for systems with random disorder; 5. present general outlook on various applications of the dynamical mean-field theory in condensed matter physics.

Quantum gate design: From superconducting circuits to nanoelectromechanical systems
 
Summary
I will discuss methods we are developing for the design of quantum computing architectures based on superconducting circuits coupled to electromagnetic or nanoelectromechanical resonators, architectures which are currently being pursued experimentally at UC Santa Barbara. The methods allow one to theoretically determine the actual computational power of a proposed quantum computing architecture and to design and optimize real quantum gates and algorithm implementations. After an introduction to quantum electrical circuits and quantum nanoelectromechanical systems, the gate design methods will be used to develop quantum memory elements and controlled-NOT logic for the Santa Barbara architectures.

Bengt Lundqvist (Göteborg, Sweden)
Density-Functional Theory of Dense and Sparse Matter
 
Summary
This review of the density-functional theory (DFT) first reminds ourselves about the basis of DFT. Particular focus is on the exchange-correlation energy, the so-called adiabatic-connection formula for it, and on some approximations for it, the local-density approximation (LDA), the general-gradient approximation (GGA), and a recently developed density functional for sparse matter (vdW-DF), i.e. one that accounts for van der Waals (vdW) forces. Then some examples of applications on dense and sparse matter are brought up from the author's experience. The wellknown applicability of DFT with GGA for dense systems is illustrated on bulk and surface properties of materials in hard tools, like TiC, TiN, and Al2O3. Applications to sparse systems, like graphite, benzene adsorption on graphite, and DNA base pairs, show the vdW-DF functional to be promising. Finally, an attempt is made to assess the value and the limitations of the DFT.

Physics of carbon nanostructures
 
Summary
Carbon is a prominent element that appears in various structures with new promising technological applications. The physics of carbon nanostructures is one of the hot topics in modern condensed matter theory. I plan to present a brief introduction into the theory of variously shaped carbon nanostructures paying special attention to generic field-theory models. The preliminary plan is the following:
(1) a brief historical excursus,
(2) the most interesting experimental observations,
(3) generic models for the description of electronic states in carbon nanoparticles (Dirac-type equations, defects, geometry, etc.),
(4) open problems.
