Abstract:
The subject of this work is the development of PIMC algorithms in various fields of quantum theory and condensed matter physics and their application for some important problems of physics. A high-performance muti-level algorithm is designed for many-body quantum systems calculations. This algorithm is applied for a computation of a metal hydrogen model. Within this model equations of state are obtained in a wide range of densities and temperatures. A first kind phase transition between liquid and bcc cubic crystal is detected and explored. A correct algorithm of PIMC calculations for relativistic quantum theory is also designed.
