During the last decade, the standards of writing scientific software and numerical libraries have been steadily improving. This resulted in a large number of available packages for scientific computing in many different research areas.

Young researchers and PhD students are now able to perform cutting-edge research just using such publicly available software. However, young scientists often need to enhance some software components, to add some new features to the existing software packages, or to write completely new scientific code, re-using some of the existing elements, or completely from scratch. This usually seems as a difficult task to young researchers, and often the effort to produce high quality scientific software is overestimated.
Young scientists, not formally trained in software engineering techniques, are not aware of important tools and often do not use good software designing and programming practices, thus lowering considerably their efficiency in either using scientific software packages or performing scientific software development.
The School is organized to address this and eliminate/alleviate identified obstacles for young researchers to be more easily involved in the software development, with specific focus on developing countries.

The goal of this School is to fill the identified gap in the training related to the software development, and to provide young scientists with the basic skills necessary to efficiently write their own scientific codes, optimize, port and benchmark them properly, and to employ the right computational infrastructure effectively.

The School will be organized in two weeks. The first week will be dedicated to scientific software engineering concepts/tools, with the emphasis on topics such as: software life cycle, writing and managing scientific software, compiling, debugging, and re-using the code etc. Theoretical lectures will be combined with the practical exercises in computer laboratories where students will practice the concepts discussed during the lectures on their own scientific software project. The second week will be then entirely dedicated to complete personal and/or group projects.

Students will work actively on their own specific software and computational problems that should be attached to the application, according to below template ("Research project questionnaire - case to work on during the School"). A preliminary good knowledge of Linux OS is required.

(Hongyi XIE) - Seminar on on Disorder and strong electron correlations: "Localization of hybrid particles"

Room: Leonardo da Vinci Building Luigi Stasi Seminar Room

Motivated by various disordered propagation problems with competing channels, I study the representative problem of Anderson localization on an asymmetric two-leg ladder. The problem is solved by the Fokker-Planck approach, which is exact in the weak disorder limit. The localization radius of various one dimensional systems, such as a polaritons or other hybrid particles, can be investigated by this model. These applications correspond to parametrically different intra-chain hopping integrals and/or different disorder amplitudes on the two legs, situations in which it is non-trivial to predict what dominates the transport in the joint system.
An extended Dorokhov-Mello-Pereya-Kumar (DMPK) equation is obtained and solved analytically. Two localization lengths are obtained as functions of the parameters of the model. We find that: 1) Near the resonance energy (where the dispersion curves of the two decoupled and disorder-free
chains intersect) the "slow'' chain dominates the localization properties of the ladder. 2) Away from the resonance the "fast'' chain dominates the transmission probability.
