The program will concentrate on two topics, (i) Large Coulomb Systems and
(ii) Quantum Information and Reduced Density Matrices. The corresponding parts will start with kick-off workshops during the first and third week of the program.

The program will be organized in two related sections, but with different emphasis, namely “Large Coulomb Systems” and “Quantum Information and N-Representability”. The topics of the program will include:

• Effective description of atoms and molecules (density and density matrix functionals, computational aspects)

• Models of relativistic quantum electrodynamics

• Stability of matter (including relativistic systems and the quantized photon field)

• Lieb-Thirring and other Sobolev type inequalities

• Reduced density matrices and the N-representability problem in quantum information theory

• Quantum and Classical Complexity Theory of the N-representability and related physical problems

• Approximation methods for correlated states (Semi-definite programming, Matrix Product States (MPS), Projected Entangled Pair States (PEPS), fermionic PEPS)

These topics mark an area of considerable current research activity. The goal of the program is not only to communicate recent research results and initiate collaboration between the mathematicians and physicists that take part in the respective research effort, it is also intended to initiate collaboration between participants of the many-particle community and the quantum information community.

The first four weeks will emphasize the theory of Large Coulomb System, the last four weeks (there will be an overlap of two weeks) will emphasize Quantum Information and N-Representability. Each part will start with a kick-off workshop. The first workshop will start February 17, the second on March 1. Each workshop will be followed by working periods on the topics raised during the workshop. As part of the workshops, lead participants will give introductory talks into the current state of research. Also at the beginning of each period, there will be tutorial lectures directed towards graduate students, postdocs, and scientist interested in starting work in the area of large Coulomb systems and quantum electrodynamics, followed by a working and collaboration session of three weeks. The tutorial lectures is planned to consist of five two hour sessions.
