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

A major challenge in operating multiqubit quantum processors is to mitigate multiqubit
coherent errors. For superconducting circuits, besides crosstalk originating from imperfect …

Ferromagnetism is a manifestation of strong repulsive interactions between itinerant
fermions in condensed matter. Whether short-ranged repulsion alone is sufficient to stabilize …

We exploit a time-resolved pump-probe spectroscopic technique to study the out-of-
equilibrium dynamics of an ultracold two-component Fermi gas, selectively quenched to …

Fast obstacles in a medium are responsible for striking physical phenomena, such as
aerodynamic flutter, Čerenkov radiation and acoustic shock waves. In a hydrodynamic …

Trapping ultracold atoms in optical lattices enabled numerous breakthroughs uniting several
disciplines. Coupling these systems to quantized light leads to a plethora of new …

A complete set of generalized spin-squeezing inequalities is derived for an ensemble of
particles with an arbitrary spin. Our conditions are formulated with the first and second …

Violating Bell's inequalities (BIs) allows one to certify the preparation of entangled states
from minimal assumptions—in a device-independent manner. Finding BIs tailored to many …

We present a method for measuring magnetic field gradients with macroscopic singlet states
realized with ensembles of spin-j particles. While the singlet state is completely insensitive to …

We extend the criteria for k-particle entanglement from the spin-squeezing parameter
presented in Sørensen and Mølmer [Phys. Rev. Lett. 86, 4431 (2001) PRLTAO 0031-9007 …
