Multiscale measures of phase-space trajectories [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2020 Characterizing the multiscale nature of fluctuations from nonlinear and nonstationary time series is one of the most intensively studied contemporary problems in nonlinear sciences. In this work, we address this problem by combining two established concepts—empirical mode decomposition (EMD) and generalized fractal dimensions—into a unified analysis ...

Probabilistic Phase Space Trajectory Description for Anomalous Polymer Dynamics [PDF]
Journal of Physics: Condensed Matter, 2011 It has been recently shown that the phase space trajectories for the anomalous dynamics of a tagged monomer of a polymer --- for single polymeric systems such as phantom Rouse, self-avoiding Rouse, Zimm, reptation, and translocation through a narrow pore

Quantum trajectory phase transitions in the micromaser [PDF]
Physical Review E, 2011 We study the dynamics of the single atom maser, or micromaser, by means of the recently introduced method of thermodynamics of quantum jump trajectories.

Trajectory phase transitions in noninteracting spin systems [PDF]
Physical Review E, 2020 We show that a collection of independent Ising spins evolving stochastically can display surprisingly large fluctuations towards ordered behaviour, as quantified by certain types of time-integrated plaquette observables, despite the underlying dynamics being non-interacting.

Geometric phases along quantum trajectories
Quantum, 2023 A monitored quantum system undergoing a cyclic evolution of the parameters governing its Hamiltonian accumulates a geometric phase that depends on the quantum trajectory followed by the system on its evolution. The phase value will be determined both by the unitary dynamics and by the interaction of the system with the environment.

Applying spline-based phase analysis to macroeconomic dynamics
Dependence Modeling, 2022 The article uses spline-based phase analysis to study the dynamics of a time series of low-frequency data on the values of a certain economic indicator. The approach includes two stages. At the first stage, the original series is approximated by a smooth
