Stochastic Hierarchical Systems: Excitable Dynamics [PDF]
Journal of Biological Physics, 2008 We present a discrete model of stochastic excitability by a low-dimensional set of delayed integral equations governing the probability in the rest state, the excited state, and the refractory state. The process is a random walk with discrete states and nonexponential waiting time distributions, which lead to the incorporation of memory kernels in the ...

Roundabout relaxation: collective excitation requires a detour to equilibrium [PDF]
, 2004 Relaxation to equilibrium after strong and collective excitation is studied, by using a Hamiltonian dynamical system of one dimensional XY model. After an excitation of a domain of $K$ elements, the excitation is concentrated to fewer elements, which are

Dynamics of nonlinear excitations of helically confined charges [PDF]
, 2015 We explore the long-time dynamics of a system of identical charged particles trapped on a closed helix. This system has recently been found to exhibit an unconventional deformation of the linear spectrum when tuning the helix radius.

Modeling excitable systems: Reentrant tachycardia [PDF]
American Journal of Physics, 2009 Excitable membranes are an important type of nonlinear dynamical system, and their study can be used to provide a connection between physical and biological circuits. We discuss two models of excitable membranes important in cardiac and neural tissues.

Noise reduction in atomic force microscopy: Resonance contact mode [PDF]
, 1996 Noise reduction has been accomplished in atomic force microscopy by applying a high frequency, low amplitude vibration to the cantilever while it is in contact with a surface.

Skyrmion excitations in quantum Hall systems [PDF]
Physical Review B, 1996 Using finite size calculations on the surface of a sphere we study the topological (skyrmion) excitation in quantum Hall system with spin degree of freedom at filling factors around $ =1$. In the absence of Zeeman energy, we find, in systems with one quasi-particle or one quasi-hole, the lowest energy band consists of states with $L=S$, where $L$ and $
