Thermal self-synchronization of nano-objects

چکیده
Self-synchronization is a ubiquitous phenomenon in nature, which oscillators are collectively locked frequency and phase through mutual interactions. While self-synchronization requires the forced excitation of at least one oscillators, we demonstrate that this mechanism spontaneously appears due to activation from thermal fluctuations. By performing molecular dynamics simulations, platform supporting doped silicon resonator nanopillars having different eigenfrequencies. We find pillar’s vibrations converging same phase. In addition, dependencies on intrinsic difference coupling strength agree well with Kuramoto model predictions. More interestingly, balance between energy dissipation resulting phonon–phonon scattering potential reached maintain synchronization. The could be suppressed by increasing membrane size. microscopic stochastic motions known follow random probability distributions, finally prove they can also yield coherent collective via self-synchronization.

Angle restriction enhances synchronization of self-propelled objects.
Understanding the synchronization process of self-propelled objects is of great interest in science and technology. We propose a synchronization model for a self-propelled objects system in which we restrict the maximal angle change of each object to θ(R). At each time step, each object moves and changes its direction according to the average direction of all of its neighbors (including itself)...
متن کاملKohonen Self Organizing for Automatic Identification of Cartographic Objects
Automatic identification and localization of cartographic objects in aerial and satellite images have gained increasing attention in recent years in digital photogrammetry and remote sensing. Although the automatic extraction of man made objects in essence is still an unresolved issue, the man made objects can be extracted from aerial photos and satellite images. Recently, the high-resolution s...
متن کاملFractional synchronization of spin-torque nano-oscillators.
We experimentally demonstrate a series of fractional synchronization regimes (Devil's staircase) in a spin-torque nano-oscillator driven by a microwave field. These regimes are characterized by rational relations between the driving frequency and the frequency of the oscillation. An analysis based on the phase model of auto-oscillator indicates that fractional synchronization becomes possible w...
متن کاملSelf-synchronization and controlled synchronization
An attempt is made to give a general formalism for synchronization in dynamical systems encompassing most. of the known definitions and applications. The proposed set-up describes synchronization of interconnected systems with respect to a set of functionals and captures peculiarities of both self-synchronization and controlled synchronization. Various illustrative examples are given.
متن کاملSpecifying the PREMO Synchronization Objects
This paper describes the formal specification of object types for managing inter-media synchronisation and control within PREMO, an emerging ISO/IEC standard for multimedia systems. Object-Z, an object-oriented extension to the Z specification language, is used for this purpose. Some aspects of PREMO are non-trivial to express in Object-Z, and the paper outlines the reasons for choosing this sp...
