Metriplectic Structure of a Radiation–Matter-Interaction Toy Model

  title={Metriplectic Structure of a Radiation–Matter-Interaction Toy Model},
  author={Massimo Materassi and Giulia Marcucci and Claudio Conti},
A dynamical system defined by a metriplectic structure is a dissipative model characterized by a specific pair of tensors, which defines a Leibniz bracket; and a free energy, formed by a “Hamiltonian” and an entropy, playing the role of dynamics generator. Generally, these tensors are a Poisson bracket tensor, describing the Hamiltonian part of the dynamics, and a symmetric metric tensor, that models purely dissipative dynamics. In this paper, the metriplectic system describing a simplified two…

Algebrizing friction: a brief look at the Metriplectic Formalism

The formulation of Action Principles in Physics, and the introduction of the Hamiltonian framework, reduced dynamics to bracket algebra of observables. Such a framework has great potentialities, to

Entropy as a Metric Generator of Dissipation in Complete Metriplectic Systems

This lecture is a short review on the role entropy plays in those classical dissipative systems whose equations of motion may be expressed via a Leibniz Bracket Algebra (LBA). This means that the

Metriplectic torque for rotation control of a rigid body

Metriplectic dynamics couple a Poisson bracket of the Hamiltonian description with a kind of metric bracket, for describing systems with both Hamiltonian and dissipative components. The construction

Metriplectic Algebra for Dissipative Fluids in Lagrangian Formulation

The dynamics of dissipative fluids in Eulerian variables may be derived from an algebra of Leibniz brackets of observables, the metriplectic algebra, that extends the Poisson algebra of the

Irreversible evolution of a wave packet in the rigged-Hilbert-space quantum mechanics

It is well known that a state with complex energy cannot be the eigenstate of a self-adjoint operator, such as the Hamiltonian. Resonances, i.e., states with exponentially decaying observables, are

Amplification of non‐Markovian decay due to bound state absorption into continuum

It is known that quantum systems yield non‐exponential (power law) decay on long time scales, associated with continuum threshold effects contributing to the survival probability for a prepared

Nonlinear optics.

In this method, non-linear susceptibility tensors are introduced which relate the induced dipole moment to a power series expansion in field strengths and the various experimental observations are described and interpreted in terms of this formalism.
