We propose a magnetomechanical device that exhibits many properties of a laser. The device is formed by a nanocantilever and dynamically polarized paramagnetic nuclei of a solid sample in a strong external magnetic field. The corresponding quantum oscillator and effective two-level systems are coupled by the magnetostatic dipole-dipole interaction between a permanent magnet on the cantilever tip and the magnetic moments of the spins, so that the entire system is effectively described by the…

Magnetic resonance in an atomic vapor excited by a mechanical resonator
We demonstrate a direct resonant interaction between the mechanical motion of a mesoscopic resonator and the spin degrees of freedom of a sample of neutral atoms in the gas phase. This coupling,
Chip Scale Atomic Magnetometers
An optically pumped magnetometer was drastically miniaturized, by taking advantage of MEMS techniques, producing the chip-scale atomic magnetometers (CSAM) physics package. The key component of the
Analogue of cavity quantum electrodynamics for coupling between spin and a nanomechanical resonator: Dynamic squeezing and coherent manipulations
In the cavity QED analogue for the coupling system of a spin and a nanomechanical resonator, we show that, when the nanomechanical resonator is quantized, a spin-boson model for this coupling system
A Bose-Einstein condensate coupled to a micromechanical oscillator
This thesis reports experiments on the interaction between a Bose-Einstein condensate (BEC) of magnetically trapped Rb atoms and the motion of a micromechanical oscillator. We make use of the
Phonon laser effect and Dicke-Hepp-Lieb superradiant phase transition in magnetic cantilever coupled to a Bose-Einstein condensate
We propose the possibility of a phonon laser by coupling a Bose–Einstein condensate to a nanomechanical cantilever with a magnetic tip. Due to the magnetic coupling, atomic spin flips induce
Coherent Sensing of a Mechanical Resonator with a Single-Spin Qubit
TLDR
It is demonstrated that the coherent evolution of a single electronic spin associated with a nitrogen vacancy center in diamond can be coupled to the motion of a magnetized mechanical resonator, providing the opportunity to probe minute mechanical motion that would otherwise be undetectable.
A trapped-ion phonon laser and the detection of ultra-weak forces
This dissertation reports on the demonstration of a mechanical analogue to an optical laser, a ”phonon laser”, using a single trapped ion. Furthermore, we show that the dynamics of this system are
Phonon maser stimulated by spin postselection
In a sequence of single spins interacting dispersively with a mechanical oscillator, and using the micromaser model with random injection, we show that after an appropriate post-selection of each
The effect of Landau–Zener dynamics on phonon lasing
Optomechanical systems couple light to the motion of nanomechanical objects. Intriguing new effects are observed in recent experiments that involve the dynamics of more than one optical mode. There,
An optical tweezer phonon laser
Phonon lasers are mechanical analogues of the ubiquitous optical laser and have been realized in a variety of contexts1–12. However, no such demonstration exists for mesoscopic levitated

TLDR
The simplified description of the phenomena involved in MR is intended to be comprehensive and does not require foreknowledge of classical physics, quantum mechanics, fluency with mathematical formulae or an understanding of image reconstruction.
