Transient electric current through an Aharonov-Bohm ring after switching of a Two-Level-System

, 2001
Response of the electronic current through an Aharonov-Bohm ring after a two-level-system is switched on is calculated perturbatively by use of non-equilibrium Green function.

Neutrino Oscillations in Intermediate States.II -- Wave Packets [PDF]

, 2005
We analyze oscillations of intermediate neutrinos in terms of the scattering of particles described by Gaussian wave packets. We study a scalar model as in a previous paper (I) but in realistic situations, where the two particles of the initial state and

Spin–transfer torque oscillator in magnetic tunneling junction with short–wavelength magnon excitation

AIP Advances, 2018
Bloch–Bloembergen–Slonczewski (BBS) equation is established by extending Bloch–Bloembergen equation, and it is used to study magnetization oscillation in the free magnetic layer of a magnetic tunneling junction.

Stochastic and chaotic relaxation oscillations [PDF]

Journal of Statistical Physics, 1989
For relaxation oscillators stochastic and chaotic dynamics are investigated. The effect of random perturbations upon the period is computed. For an extended system with additional state variables chaotic behavior can be expected. As an example, the Van der Pol oscillator is changed into a third-order system admitting period doubling and chaos in a ...

Inferring characteristic timescales from the effect of autoregressive dynamics on detrended fluctuation analysis

New Journal of Physics, 2019
Exploiting recent progress in the theoretical understanding of detrended fluctuation analysis (DFA), we use the non-asymptotic properties of the fluctuation function in order to extract more information from time series data than just its Hurst exponent.

Relaxation time and critical slowing down of a spin-torque oscillator

, 2017
The relaxation phenomena of spin-torque oscillators consisting of nanostructured ferromagnets are interesting research targets in magnetism. A theoretical study on the relaxation time of a spin-torque oscillator from one self-oscillation state to another

Relaxation Tribometry: A Generic Method to Identify the Nature of Contact Forces [PDF]

, 2019
Recent years have witnessed the development of so-called relaxation tribometers, the free oscillation of which is altered by the presence of frictional stresses within the contact. So far, analysis of such oscillations has been restricted to the shape of

Halted-pendulum Relaxation: Application to White Dwarf Binary Initial Data

The Astrophysical Journal, 2023
Studying compact-star binaries and their mergers is integral to determining progenitors for observable transients. Today, compact-star mergers are typically studied via state-of-the-art computational fluid dynamics codes.

Influence of pH on mechanical relaxations in high solids lm-pectin preparations [PDF]

, 2015
The influence of pH on the mechanical relaxation of LM-pectin in the presence of co-solute has been investigated by means of differential scanning calorimetry, ζ-potential measurements and small deformation dynamic oscillation in shear.
