Fluid-particle interactions and fluctuation-dissipation relations III -- Correlated fluctuations, regularity and added mass
Massimiliano Giona, Giuseppe Procopio, Chiara Pezzotti
The fluctuation-dissipation theory is grounded on the Langevin condition expressing the local independence between the thermal force and the particle velocity history. Upon hydrody…
Fluid-particle interactions and fluctuation-dissipation relations II -- Gaussianity and Gaussianity breaking
Chiara Pezzotti, Massimiliano Giona, Giuseppe Procopio
The analysis of fluctuation-dissipation relations developed in Giona et al. (2024) for particle hydromechanics is extended to stochastic forcings alternative to Wiener processes, w…
Fluid-particle interactions and fluctuation-dissipation relations I -- General linear theory and basic fluctuational patterns
Massimiliano Giona, Giuseppe Procopio, Chiara Pezzotti
The article provides a unitary and complete solution to the fluctuation-dissipation relations for particle hydromechanics in a generic fluid, accounting for the hydrodynamic fluid-…
Generalized fluctuation-dissipation relations in confined geometries and concentrated conditions
Massimiliano Giona, Giuseppe Procopo, Chiara Pezzotti
his article extends the fluctuation-dissipation analysis to generic complex fluids in confined geometries and to all the cases the hydromechanic fluid-interaction kernels may depen…
On the ergodicity breaking in well-behaved Generalized Langevin Equations
Giuseppe Procopio, Chiara Pezzotti, Massimiliano Giona
The phenomenon of ergodicity breaking of stochastic dynamics governed by Generalized Langevin Equations (GLE) in the presence of well-behaved exponentially decaying dissipative mem…
Dynamic fluctuation-dissipation theory for Generalized Langevin Equations: constructive constraints, stability and realizability
Massimiliano Giona, Giuseppe Procopio, Chiara Pezzotti
Using the initial-value formulation, a dynamic theory for systems evolving according to a Generalized Langevin Equation is developed, providing more restrictive conditions on the e…
