Nonlinear theory of laser-induced dipolar interactions in arbitrary geometry

Nonlinear effects from dipolar interactions in hyperpolarized liquid 129Xe.

We investigate nonlinear effects of long-range dipolar interactions in a spherical sample of hyperpolarized liquid 129Xe. Using two high-T(c) SQUID detectors we directly measure the evolution of the magnetization gradients. For small initial rf tip angles we observe an increase in the transverse relaxation time T2* by a factor of 5 and coherent oscillations of magnetization gradients. For large...

Nonlinear Vibration Analysis of a cantilever beam with nonlinear geometry

Analyzing the nonlinear vibration of beams is one of the important issues in structural engineering. According to this, an impressive analytical method which is called Modified Iteration Perturbation Method (MIPM) is used to obtain the behavior and frequency of a cantilever beam with geometric nonlinear. This new method is combined by the Mickens and Iteration methods. Moreover, this method don...

Interactions between Lie Theory and Algebraic Geometry

Interactions between model theory and geometry

Model theory is in a period of rich activity. Advances in pure model theory are finding immediate applications, in particular to the model theory of fields, while the applications are themselves motivating the abstract developments. Applied model theory is using ideas and methods from other parts of mathematics, ranging from homology theory to complex analytic geometry. These two strands of res...
