Incoherent magnetism
WebOne example is the collective version of the Lamb shift that we could observe by embedding ultrathin layers of resonant 57 Fe nuclei into an x-ray cavity. Cavities facilitate to realize a very accurate control of the light-matter interaction at x-ray energies. This enabled us to demonstrate one of the key phenomena of quantum optics ... WebThe coercivity [41–56] of magnetic nanoparticles has a striking dependence on their size, as shown in Fig. 2.1. The coercivity Hc is zero below the superparamagnetic (SP) particle size limit r0, single-domain (SD) behavior (SD) is shown between r0 and the single-domain limit rc, and multi-domain (MD) behavior for r > rc.

In physics, two wave sources are coherent if their frequency and waveform are identical. Coherence is an ideal property of waves that enables stationary (i.e., temporally or spatially constant) interference. It contains several distinct concepts, which are limiting cases that never quite occur in reality but allow … See more Coherence was originally conceived in connection with Thomas Young's double-slit experiment in optics but is now used in any field that involves waves, such as acoustics, electrical engineering, neuroscience, … See more The coherence of two waves expresses how well correlated the waves are as quantified by the cross-correlation function. Cross-correlation quantifies the ability to predict the phase of the second wave by knowing the phase of the first. As an example, consider … See more Temporal coherence is the measure of the average correlation between the value of a wave and itself delayed by τ, at any pair of times. Temporal coherence tells us how monochromatic a source is. In other words, it characterizes how well a wave can interfere with … See more Waves of different frequencies (in light these are different colours) can interfere to form a pulse if they have a fixed relative phase-relationship … See more The coherence function between two signals $${\displaystyle x(t)}$$ and $${\displaystyle y(t)}$$ is defined as $${\displaystyle \gamma _{xy}^{2}(f)={\frac { S_{xy}(f) ^{2}}{S_{xx}(f)S_{yy}(f)}}}$$ where See more These states are unified by the fact that their behavior is described by a wave equation or some generalization thereof. • Waves … See more In some systems, such as water waves or optics, wave-like states can extend over one or two dimensions. Spatial coherence describes the ability for two points in space, x1 and x2, in the extent of a wave to interfere, when averaged over time. More precisely, the spatial … See more WebMar 3, 2024 · For the magnon spectra, we convoluted the dynamic structure factor S ij (q, E) with the instrumental resolution, taking into account incoherent magnetic scattering (for …
