Quantum Particle-Trajectories and Geometric Phase [PDF]
Journal of Experimental and Theoretical Physics Letters, 2002 "Particle"-trajectories are defined as integrable $dx_\mu dp^\mu = 0$ paths in projective space. Quantum states evolving on such trajectories, open or closed, do not delocalise in $(x, p)$ projection, the phase associated with the trajectories being ...

On geometric phases for quantum trajectories [PDF]
Acta Physica Hungarica A) Heavy Ion Physics, 2006 A sequence of completely positive maps can be decomposed into quantum trajectories. The geometric phase or holonomy of such a trajectory is delineated. For nonpure initial states, it is shown that well-defined holonomies can be assigned by using Uhlmann ...

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.

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 ...

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.

Mathematical Model of Fractional Duffing Oscillator with Variable Memory
Mathematics, 2020 The article investigates a mathematical model of the Duffing oscillator with a variable fractional order derivative of the Riemann–Liouville type. The study of the model is carried out using a numerical scheme based on the approximation of the fractional

Stochastic dynamics of single molecules across phase boundaries
Physical Review Research, 2021 We discuss the stochastic trajectories of single molecules in a phase-separated liquid, when a dense and a dilute phase coexist. Starting from a continuum theory of macroscopic phase separation we derive a stochastic Langevin equation for molecular ...
