Random hysteresis loops

Dynamical hysteresis is a phenomenon which arises in ferromagnetic systems below the critical temperature as a response to adiabatic variations of the external magnetic field. We study the problem in the context of the mean-field Ising model with Glauber dynamics, proving that for frequencies of the magnetic field oscillations of order N−2/3, N the size of the system, the “critical” hysteresis ...

Understanding simulated driver behavior using hysteresis loops

Modeling techniques evolved a lot during the last half century. Acceleration models used for microscopic traffic simulation are heterogeneous. For instance, differential equation based models are different from agent based ones. Comparison of those models is a difficult task because studies are often conducted based on a suitable and particular theory, usually not applicable to all models. So w...

Subharmonics and aperiodicity in hysteresis loops.

We show that it is possible to have hysteretic behavior for magnets that does not form simple closed loops in steady state, but cycles multiple times before returning to its initial state. We show this by studying the low temperature dynamics of the 3D Edwards-Anderson spin glass. The specific multiple varies from system to system and is often quite large and increases with system size. The las...

Clockwise Hysteresis Loops in the Macroscopic Fundamental Diagram

A recent study reported that the Macroscopic Fundamental Diagram of a medium size city exhibited a clockwise hysteresis loop on a day in which a major disturbance caused many drivers to switch to unfamiliar routes. This paper shows that clockwise loops are to be expected when there are disturbances, especially if the disturbances cause a significant fraction of the drivers to not change routes ...

Anomalous magneto-optical Kerr hysteresis loops in Fe0.25TaS2

We have performed magneto-optical Kerr spectroscopy measurements on intercalated transition-metal dichalcogenide Fe0.25TaS2 in the polar Kerr geometry as a function of temperature, magnetic field, and wavelength. The Kerr angle exhibits pronounced peaks at ∼775 nm (1.6 eV) and ∼515 nm (2.4 eV), which we attribute to spin-dependent interband optical transitions arising from states in the vicinit...
