Global population crisis scenarios predicted by a general nonlinear dynamical model
Alessio Zaccone, Kostya Trachenko
We show that a simple nonlinear differential equation (originally studied in the physics of disordered systems) is able to mathematically describe the global population growth over…
A unified picture of phonon anomalies in crystals and glasses
Alessio Zaccone
Phonon spectra in solids often display anomalies that defy the simple Debye law, most prominently the van Hove singularity in crystals and the boson peak in glasses. Although tradi…
Open quantum systems with particle and bath driven by time-dependent fields
Daniele Gamba, Bingyu Cui, Alessio Zaccone
We derive a generalized quantum Langevin equation and its fluctuation-dissipation relation describing the quantum dynamics of a tagged particle interacting with a medium (environme…
Hyperballistic transport in dense systems of charged particles under ac electric fields
Daniele Gamba, Bingyu Cui, Alessio Zaccone
The Langevin equation is ubiquitously employed to numerically simulate plasmas, colloids and electrolytes. However, the usual assumption of white noise becomes untenable when the s…
