Noise-aided synchronization of coupled chaotic electrochemical oscillators.

- I. Kiss, J. L. Hudson, J. Escalona, P. Parmananda
- Physics, Medicine
- Physical review. E, Statistical, nonlinear, and…
- 19 August 2004

We report experimental and numerical results on noise-enhanced synchronization of two coupled chaotic oscillators. Enhanced synchronization is achieved through superimposing small-amplitude Gaussian… Expand

Fibonacci order in the period-doubling cascade to chaos

- G. Linage, F. Montoya, A. Sarmiento, K. Showalter, P. Parmananda
- Physics
- 11 December 2006

Abstract In this contribution, we describe how the Fibonacci sequence appears within the Feigenbaum scaling of the period-doubling cascade to chaos. An important consequence of this discovery is that… Expand

Mathematical model simulating the growth of compound semiconductor thin films via chemical bath deposition

- P. K. Nair, P. Parmananda, M. Nair
- Chemistry
- 1 October 1999

Abstract Chemical bath deposition is a thin film technique in which compound semiconductor thin films of typically 0.02–1 μm thickness are deposited on the substrates immersed in dilute baths… Expand

Alternating chaotic and periodic dynamics in Chern-Simons-Higgs theory with scalar magnetic interaction.

- J. Escalona, A. Antillón, M. Torres, Y. Jiang, P. Parmananda
- Physics, Medicine
- Chaos
- 31 May 2000

The dynamical behavior of a Chern-Simons-Higgs system is studied for the spatially homogeneous case. The model, described by interacting gauge and scalar fields includes two parity and time violating… Expand

Experimental evidence of coexisting periodic stochastic resonance and coherence resonance phenomena.

- Gerardo J. Escalera Santos, M. Rivera, P. Parmananda
- Physics, Medicine
- Physical review letters
- 11 June 2004

We report evidence of coexisting period stochastic resonance (PSR) and coherence resonance (CR) phenomena in an electrochemical cell. The anodic voltage (V) in the cell is chosen such that the anodic… Expand
