Non-Lie Point Symmetry and Coherent Soliton Solutions of Nizhnik-Novikov-Veselov Equation
Lax pair symmetries symmetry group exact solution
2012/9/24
A new method is presented to find the finite symmetry groups of nonlinear physics systems. For the (2+1)-dimensional Nizhnik-Novikov-Veselov (NNV) equation, both the Lie point symmetry and the non-Lie...
A New Form of Path Integral for the Coherent States Representation and its Semiclassical Limit
Path Integral the Coherent States Representation Semiclassical Limit
2010/10/13
The overcompleteness of the coherent states basis leads to a multiplicity of representations of Feynman’s path integral. These different representations, although equivalent quantum mechanically, lead...
The Potentialities of Coherent X-Radiation for Self-Assembled Systems and Liquid Crystal Research
Coherent X-Radiation Self-Assembled Systems Liquid Crystal Research
2010/10/25
The potentialities of coherent X-radiation for investigation of structural features of self-assembled systems and liquid crystals was studied using Monte Carlo techniques. The radiation spectra were s...
