Long-time fidelity and chaos for a kicked nonlinear oscillator system

, 2009
We deal with a system comprising a nonlinear (Kerr-like) oscillator excited by a series of ultra-short external pulses. We introduce the fidelity-based entropic parameter that can be used as an indicator of quantum chaos.

Review of Memristors for In‐Memory Computing and Spiking Neural Networks

Advanced Intelligent Systems, EarlyView.
Memristors uniquely enable energy‐efficient, brain‐inspired computing by acting as both memory and synaptic elements. This review highlights their physical mechanisms, integration in crossbar arrays, and role in spiking neural networks. Key challenges, including variability, relaxation, and stochastic switching, are discussed, alongside emerging ...

God, Chaos, and the Quantum Dice

Zygon, 2000
A recent noninterventionist account of divine agency has been proposed that marries the probabilistic nature of quantum mechanics to the instability of chaos theory. On this account, God is able to bring about observable effects in the macroscopic world

Chaos and complexity by design

Journal of High Energy Physics, 2017
We study the relationship between quantum chaos and pseudorandomness by developing probes of unitary design. A natural probe of randomness is the “frame poten-tial,” which is minimized by unitary k-designs and measures the 2-norm distance between the ...

Structural, Superconducting and Magnetic Properties of Oxygen‐Annealed Fe1+yTe Thin Films

Advanced Physics Research, EarlyView.
FeTe:Ox films exhibit exchange bias below their Néel temperatures, which coexists with superconductivity. STEM analysis reveals the structural changes induced by oxygen treatment. DFT calculations indicate that interstitial oxygen suppresses antiferromagnetism and promotes superconductivity.

Chaotic roots of the modular multiplication dynamical system in Shor's algorithm

Physical Review Research
Shor's factoring algorithm, believed to provide an exponential speedup over classical computation, relies on finding the period of an exactly periodic quantum modular multiplication operator. This exact periodicity is the hallmark of an integrable system,

Nonlinear Active Site Dynamic Behavior Over In Situ Generated Working Zeolites

Chemie Ingenieur Technik, EarlyView.
The methoxymethyl mechanism over α, β, and γ site ensembles and the dynamic site‐interconversion mechanism reduce the induction period of propylene formation. The methoxymethyl mechanism acts on site ensemble α generating surface methoxy species (SMS), which, through the dynamic site‐interconversion mechanism, lead to SMS on site ensembles β and γ that

Quantum logic automata generalizing the edge of chaos in complex systems

Frontiers in Complex Systems
BackgroundHistorically, although researchers in the science of complex systems proposed the idea of the edge of chaos and/or self-organized criticality as the essential feature of complex organization, they were not able to generalize this concept ...
