This study explores Lotka-Volterra (LV) dynamics using Weyl-Wigner (WW) quantum mechanics, revealing how quantum effects modify classical prey-predator models. It quantifies quantum analog effects in biological systems.
Area of Science:
- Quantum Mechanics
- Theoretical Ecology
- Statistical Physics
Background:
- The Lotka-Volterra (LV) model describes predator-prey population dynamics.
- Classical Hamiltonian mechanics is often used to study LV dynamics.
- Understanding quantum effects in biological systems is an emerging area.
Purpose of the Study:
- To investigate LV dynamics within an extended Weyl-Wigner (WW) quantum mechanics framework.
- To explore the coexistence of classical and quantum evolution.
- To quantify quantum analog effects on ecological models.
Main Methods:
- Utilizing the Heisenberg-Weyl noncommutative algebra ([x,k]=i).
- Interpreting canonical variables in terms of LV variables (y=e^{-x}, z=e^{-k}).
- Analyzing Wigner currents for thermodynamic and Gaussian quantum ensembles.
Main Results:
- The WW framework allows for the identification of classical and quantum evolution coexistence.
- Quantum features introduce corrections to the classical phase-space patterns of LV dynamics.
- Wigner flow precisely profiles quantum modifications for Gaussian ensembles, enabling comparison of quantum and classical regimes.
Conclusions:
- The developed WW framework provides a method for studying quantumlike effects in competitive biosystems.
- Gaussian quantum ensembles serve as a suitable configuration for comparing quantum and classical dynamics.
- This approach extends the understanding of quantum influences on microscopic biological interactions.
