Direct measurements of spin fluctuations are becoming the mainstream approach for studies
of complex condensed matter, molecular, nuclear, and atomic systems. This review covers …

Experimental noise often contains information about the interactions of a system with its
environment, but establishing a relation between the measured time fluctuations and the …

Multidimensional NMR spectroscopy provides a powerful tool for structure elucidation and
dynamic analysis of complex samples, particularly for biological macromolecules …

Per the fluctuation-dissipation theorem, the information obtained from spin fluctuation
studies in thermal equilibrium is necessarily constrained by the system's linear response …

NMR-based metabolomics, which emerged along with mass spectrometry techniques, is the
preferred method for studying metabolites in medical research and food industries …

Abstract Radio Amplification by Stimulated Emission of Radiation (RASER) is a
phenomenon observed during nuclear magnetic resonance (NMR) experiments with …

We discuss the effect of external noisy magnetic fields on mesoscopic spin fluctuations that
can be probed in semiconductors and atomic vapors by means of optical spin-noise …

A spin ensemble in thermal equilibrium continuously undergoes random fluctuations
analogous to those observed in Brownian motion, a process known as spin noise. Here, we …

Three optimum conditions for the tuning of NMR probes are compared: the conventional
tuning optimum, which is based on radio‐frequency pulse efficiency, the spin noise tuning …

The detection of minor species in the presence of large amounts of similar main components
remains a key challenge in analytical chemistry, for instance, to obtain isotopic fingerprints …
