Abstract The Academic and Educational Grid Initiative of Serbia hosts and
maintains the scienti
c gateway of the Serbian condensed matter physics com-
munity. The gateway is built around a code set addressing problems from the
physics of ultracold quantum gases, solving the nonlinear Schroedinger equation,
the Gross
Pitaevskii equation in real and imaginary time, and a path integral
algorithm for estimation of quantum-mechanical transition amplitudes, which are
relevant for various applications. Here we present the realization of the gateway and
technologies used for its implementation.

15.1 Introduction
Condensed matter physics and materials science address problems that highly rel-
evant for fundamental research, as well as for practical applications and society.
The development of high-impact materials with enhanced and engineered proper-
ties, or research in quantum information, for example, depend on the results from
these areas of physical sciences, and contribute to the IT and smartphone industry,
semiconductor technology, the energy sector, and others.
Numerical simulations are now indispensible tools in science and technology,
and are used to speed up the research and development while decreasing the costs.
In condensed matter physics, scientists deploy a broad range of algorithms, such as
solving nonlinear partial differential equations, classical and quantum Monte Carlo
techniques, including solving of the Bose
Hubbard models,
exact diagonalization techniques for strongly correlated systems, etc. Whichever
