Nonlinearity, Complexity and
applications
Research interests
We are interested in nonlinear
dynamics, statistical physics,
complexity,
stochastic processes, molecular devices and biophysical processes. In recent years
we have focused on optical metamaterials emphasizing in the role
that nonlinearity plays in these systems. Recent work
includes:
Discrete breathers and solitons in metamaterials and magnetoinductive systems:
We predicted that arrays of split ring resonators with nonlinear
capacitance may form localized modes in the form of discrete
breathers. In longer lattices left handed solitons in the form of
coupled electric and magnetic field wavey may form and propagate.
Breathers may be induced through frequency chirping also in binary
metamaterials.
Superconducting metamaterials: We introduced a squid based metamaterial and showed that it can also form discrete breathers.
Polarons in molcular systems: We have analyzed the polaron formation in proteins and other molecular sysmtes and connected these findings to acetanilide.
Dymamics and statistics of nonlinear lattices:
We have studied nonequilibrium statistics of lattices that form
breathers and connected them with glassy systems. Analyzed
various dymamical properties of breathers in nonlinear lattices.
Motor proteins: We
have introduced an electrostatic model for the kinesin walk on
microtubules and showed that it is compatible with experiments.
