2021 journal article

Construction of logic gates exploiting resonance phenomena in nonlinear systems

By: K. Murali*, S. Rajasekar*, M. Aravind*, V. Kohar*, W. Ditto n  & S. Sinha*

author keywords: stochastic resonance; logical stochastic resonance; noisy logic
TL;DR: The conventional LSR paradigm is extended to implement higher-level logic architecture or typical digital electronic structures via carefully crafted coupling schemes and to realize morphable logic gates through the Logical Coherence Resonance in excitable systems under the influence of noise.

2021 journal article

Harnessing tipping points for logic operations

EUROPEAN PHYSICAL JOURNAL-SPECIAL TOPICS, 230(16-17), 3403–3409.

By: K. Murali*, S. Sinha*, V. Kohar* & W. Ditto n 

TL;DR: The presence of tipping points in complex systems endows it with the capability to switch between very different attractors under small changes in parameter, and this feature can be exploited to obtain reliable logic operations. (via Semantic Scholar)

2018 journal article

Chaotic attractor hopping yields logic operations

PLOS ONE, 13(12).

By: K. Murali*, S. Sinha *, V. Kohar n, B. Kia n & W. Ditto n 

Ed(s): A. Adamatzky

MeSH headings : Electronics; Fuzzy Logic; Nonlinear Dynamics
TL;DR: This work explicitly demonstrates that the system hops consistently in response to an external input stream, operating effectively as a reliable logic gate, and leads to a generalization of the concept of Logical Stochastic Resonance to attractors more complex than fixed point states, such as periodic or chaotic attractors.

2017 journal article

Implementing Boolean Functions in Hybrid Digital-Analog Systems

PHYSICAL REVIEW APPLIED, 7(4).

By: V. Kohar n, B. Kia n, J. Lindner * & W. Ditto n 

TL;DR: In an ideal nonlinear map, this architecture eliminates the need for a decoder as the outputs are mapped to maxima and minima of the map and can be fed directly to the next stage enabling multilayer concatenation. (via Semantic Scholar)

Role of network topology in noise reduction using coupled dynamics

NONLINEAR DYNAMICS, 84(3), 1805–1812.

By: V. Kohar n, S. Kia n, B. Kia n, J. Lindner * & W. Ditto n 

Contributors: V. Kohar n, S. Kia n, B. Kia n, J. Lindner * & W. Ditto n 

author keywords: Network; Topology; Noise; Coupled map lattices; Coupled dynamics
TL;DR: The usefulness of coupled redundancy as a mechanism for reduction in local noise in coupled map lattices is studied and the role of network topology, coupling strength, and iteration number in this mechanism is investigated. (via Semantic Scholar)

2016 journal article

Superlinearly scalable noise robustness of redundant coupled dynamical systems

PHYSICAL REVIEW E, 93(3).

By: V. Kohar n, B. Kia n, J. Lindner * & W. Ditto n 

TL;DR: It is demonstrated that the noise robustness of redundant coupled dynamical systems can actually be scaled superlinearly if some conditions are met and very high Noise robustness can be realized with very few coupled units. (via Semantic Scholar)
