This study introduces a new framework for controlling stochastic spatio-temporal processes using measure theory and thermodynamic principles. The approach offers a variational optimization method for manipulating stochastic fields and optimizing control policies.
Area of Science:
- Physics
- Applied Mathematics
- Quantum Mechanics
Background:
- Stochastic spatio-temporal processes are fundamental in diverse scientific fields, including plasma physics, fluid dynamics, and quantum systems.
- Existing methods for analyzing and controlling these processes often lack a unified theoretical foundation.
Purpose of the Study:
- To develop a measure-theoretic framework for describing and manipulating stochastic spatio-temporal systems.
- To derive a variational optimization approach for controlling stochastic fields based on fundamental thermodynamic principles.
Main Methods:
- Describing stochastic spatio-temporal systems as evolutionary processes on Hilbert spaces.
- Applying measure-theoretic concepts to derive a control framework.
- Developing a variational optimization scheme for parameterized control policies.
Main Results:
- A novel framework for spatio-temporal manipulation derived from thermodynamic principles.
- A versatile variational optimization scheme applicable to a broad range of stochastic fields.
- Simulated experiments demonstrating the effectiveness of the proposed control methods on four distinct stochastic spatio-temporal processes.
Conclusions:
- The developed framework provides new perspectives for studying and controlling complex spatio-temporal systems.
- The variational optimization approach offers a powerful tool for optimizing control policies in stochastic environments.
- This work opens new research directions in stochastic control for spatio-temporal dynamics.

Feedback control systems
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...
