Mathematical Physics
Group: Mathematical Physics, Geometric Methods, and Applications
Team: (for Project IDEI „Geometric Methods in Gravity and Nonlinear Dynamics”, 2011-2014):
- Dr. Sergiu Vacaru – proiect leader, 100%
- Prof. Dr. Mihai Anastasiei, participant, 50%
- Tamara Gheorghiu, technician, 100%
Main research interests
Geometry and physics, mathematical physics, exact solutions in gravity; modified gravity; quantum gravity, branes and strings; cosmology and astrophysics; generalized (super) Finsler geometry; locally anisotropic stochastics, thermodynamics and kinetics; geometric quantization; Clifford and spinor structures; noncommutative geometry and gauge fields, nonholonomic Ricci flows and applications in physics; soliton, fractal, fractional derivative geometry and applications.
Main techniques involved
Geometric methods in physics, solutions of partial differential equations, analytic methods and computer modelling of nonlinear processes, diffusion and kinetics, quantum field methods in condenced matter physics, geometric analysis and evolution.
Relevant „state of the art”, equipment and techniques
Today, various directions in modern geometry and physics are so interrelated and complex that it is often very difficult to master them as separated subjects. There is a need of research teams skilled both in geometric methods and mathematical relativity and/or, inversely, theoretical and mathematical physics researches with a rigorous education in differential geometry and nonlinear analysis and computer methods. The aim of this group is to perform high level inter-disciplinary research programs on mathematical physics and applied mathematics and establish International collaborations. The team got performant laptops and soft from a Project IDEI.
