Creating integrated circuits that can generate chaotic signals

Researchers at Tokyo Institute of Technology have found a simple, yet highly versatile way to generate "chaotic signals" with various features. The technique consists of interconnecting three ring oscillators, effectively ...

Freezing upon heating: Formation of dynamical glass

The discovery of superconductivity and its experimental realization are two of the most important advancements in physics and engineering of the past century. Nevertheless, their statistical and dynamical characteristics ...

'Expansion entropy': A new litmus test for chaos?

Can the flap of a butterfly's wings in Brazil set off a tornado in Texas? This intriguing hypothetical scenario, commonly called "the butterfly effect," has come to embody the popular conception of a chaotic system, in which ...

New method speeds up stabilisation of chaotic systems

(Phys.org) —When chaos threatens, speed is essential; for example, when a pacemaker needs to stabilise an irregular heartbeat or a robot has to react to the information received from its environment. Both cases require ...

Time reversal findings may open doors to the future

(Phys.org)—Imagine a cell phone charger that recharges your phone remotely without even knowing where it is; a device that targets and destroys tumors, wherever they are in the body; or a security field that can disable ...
