Simplified exact SICS

SICS Swedish ICT SICS Technical

The liberalised railway market of today calls for new methods to plan the annual timetable. A conflict between two railway undertakings operating in the same market is hard to solve using the current method. Common price setting strategies such as auctions, framework agreements and spot markets may be of help. To administer a long term stability for an operator, framework agreements can be ente...

Converting from ECCE to SICS

Introduction Cataract continues to be the cause of almost half the cases of blindness worldwide and the challenge to meet the needs and develop the required resources is as great as ever. Cataract surgery has evolved from couching, first practised several thousand years ago, through intraand extracapsular extraction (ECCE), to phacoemulsification. However, whatever the technique, the most impor...

Simplified periodic Anderson model: Exact solution in infinite dimensions

We present a diagrammatic perturbative treatment of the hybridization for the periodic Anderson model that recovers the dynamical mean-field equations in the limit of infinite dimensions. The resulting effective singlesite problem is naturally addressed by perturbation theory on the dynamical mean field. We introduce a simplified version of the model in which only electrons with a given spin or...
