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 ...

The Classical Action as a Tool to Visualise the Phase Space of Hamiltonian Systems

Dynamics, 2023
In this paper, we analyse the classical action as a tool to reveal the phase space structure of Hamiltonian systems simply and intuitively. We construct a scalar field using the values of the action along the trajectories to analyse the phase space.

The existence of chaotic regimes of the fractional analogue of the Duffing-type oscillator

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019
In this paper, we study the chaotic regimes of the fractional Duffing oscillator. To do this, using the Wolf algorithm with Gram-Schmidt orthogonalization, we calculated the spectra of maximum Lyapunov exponents depending on the values of the control ...

Control of designed target seeker, used in self-guided anti-aircraft missiles, by employing motors with a constant torque

Aviation, 2014
This paper presents the results of research on control of a designed target seeker (Gapiński, D. 2008), which was carried out using of the so-called “signum” function. The technical feasibility of controlling the seeker axis in the phase of searching the

Quantifying measurement-induced quantum-to-classical crossover using an open-system entanglement measure

Physical Review Research, 2023
The evolution of a quantum system subject to measurements can be described by stochastic quantum trajectories of pure states. Instead, the ensemble average over trajectories is a mixed state evolving via a master equation.

Uniformity transition for ray intensities in random media [PDF]

, 2017
This paper analyses a model for the intensity of distribution for rays propagating without absorption in a random medium. The random medium is modelled as a dynamical map. After N iterations, the intensity is modelled as a sum S of N contributions from

Controlling multiple returnings in non-sequential double ionization with orthogonal two-color laser pulses

Frontiers in Physics, 2023
With the three-dimensional semi-classical ensemble model, we studied the non-sequential double ionization by orthogonal two-color laser pulses. Our calculations show that the proportion of events experiencing multiple returnings, the sum of the final ...

Quantum revival patterns from classical phase-space trajectories [PDF]

, 2019
A general semiclassical method in phase space based on the final value representation of the Wigner function is considered that bypasses caustics and the need to root-search for classical trajectories.
