A radio-frequency tunable atomic magnetometer with a sensitivity of about 1 fT/Hz 1/2 in a
range of 10–500 kHz is demonstrated. The magnetometer is operated in the orientation …

Optical quantum memories, which store and preserve the quantum state of photons, rely on
a coherent mapping of the photonic state onto matter states that are optically accessible …

Atom spin sensors occupy a prominent position in the landscape of quantum technology, as
they can combine precise measurements with appealing miniature packages that are crucial …

Magnetic sensors developed for application in magnetoencephalography must meet a
number of requirements; the main ones are compactness, sensitivity and response speed …

Spin-exchange collisions among alkali-metal atoms affect the coherence time and
gyromagnetic ratio of atoms by redistributing the ground-state population. We theoretically …

We present a method for measuring the magnetic field that allows hyperfine and Zeeman
optical pumping, excitation and detection of magnetic resonance by means of a single laser …

Phase transitions are emergent phenomena where microscopic interactions drive a
disordered system into a collectively ordered phase. Near the boundary between two …

We demonstrate an all-optical 133 Cs scalar magnetometer, operating in nonzero magnetic
field, in which the magnetic resonance is driven by an effective oscillating magnetic field …

We present a detailed experimental and theoretical study on the relaxation of spin
coherence due to the spin-exchange mechanism arising in the electronic ground states of …

Radio-frequency atomic magnetometers offer attractive alternatives to standard detection
methods in nondestructive testing, which are based on inductive measurements. We …
