Self‐organized Criticality in Neuromorphic Nanowire Networks With Tunable and Local Dynamics
Memristive nanowire networks (NWNs) are shown to be electrically tunable to a critical state where specific local dynamics evaluated by multiterminal characterization are exploited as feature selection in nonlinear transformation (NLT) tasks.

Fast-forward scaling theory for quantum dynamics on curved space-time [PDF]
Scaling properties inherent in quantum dynamics have been studied for various systems in terms of acceleration, deceleration and time reversing. We show a scaling property of quantum dynamics on curved space-time where gravity plays an essential role. We derive system parameters which realize speed-controlled dynamics.

A Description of Quantum Chaos [PDF]
A measure describing the chaos of a dynamics was introduced by two complexities in information dynamics, and it is called the chaos degree. In particular, the entropic chaos degree has been used to characterized several dynamical maps such that logistis, Baker's, Tinckerbel's in classical or quantum systems.

Light‐Mediated Photomultiplication via Cascade Energy Transfer in Organic Photodiode
Light‐mediated photomultiplication via cascade energy transfer in organic photodiode demonstrates external quantum efficiency exceeding 200% and specific detectivity surpassing 5.0 × 1013 Jones. This advancement effectively addresses the limitation of elevated dark current density characteristic of prior photomultiplication organic photodetectors ...

Work extraction from quantum systems with bounded fluctuations in work
Describing thermodynamic processes, fluctuations of work are typically not considered bounded. Here the authors show that in some processes they diverge, making the processes unphysical, and construct a framework to quantify work extraction and work of ...

Real time quantum dynamics preaveraged over imaginary time path integral: A formal basis for both Centroid Molecular Dynamics and Ring Polymer Molecular Dynamics [PDF]
An exact real time quantum dynamics preaveraged over imaginary time path integral is formulated for general condensed phase equilibrium ensemble. This formulation results in the well-known centroid dynamics approach upon filtering of centroid constraint, and provides a rigorous framework to understand and analyze a related quantum dynamics ...
