Dr. Rassul Karabalin
Dr. Rassul Karabalin is a senior research scientist at the California
Institute of Technology. He is an emerging young leader in the field of
nonlinear nanoelectromechanical systems. As a member of the Michael
Roukes research group, he is exploring NEMS as a tool for studying
complex nonlinear behavior in discrete systems. He investigated the
physical nature of nonlinear properties in NEMS and developed several
methods of controlling nonlinearity. While exploring the dynamics of
parametric resonators, he developed NEMS parametric amplifiers,
nondegenerate parametric system in strongly interacting nanomechanical
devices, and a technique of controlling the bifurcation topology of
weakly coupled NEMS resonators. He succeeded at building an array of two
strongly interacting highly nonlinear nanomechanical resonators, which
led to experimental demonstration of dynamic state transitions and
deterministic chaos. He also made significant contributions to the
development of piezoelectric depletion-mode NEMS, analysis of nonlinear
elasticity in NEMS, and nonlinear self-sustained NEMS oscillators.
