Emergent ferromagnetic states revealed in a geometrically frustrated triangular lattice

In a material, the way electrons align their spins to form a magnetic phase strongly depends on the geometry of the crystal they inhabit. In particular, triangular lattice geometries display an effect called geometrical frustration, where up and down spins cannot all be antialigned classically. This effect is thought to give rise to complex and...

CUA scientists observe microemulsion phases in the quantum melting of an electron Wigner crystal

Electrons, as quantum particles, display wave-like behavior. Forming a crystalline phase of electrons requires not only cooling but also strong Coulomb (repulsive) forces to counteract their wave-like nature. When this balance is achieved, electrons can arrange into a Wigner crystal. By adjusting electron density, a phase transition between a crystalline and liquid state can occur....

A Conveyor Belt MOT of Diatomic Molecules

Ultracold molecules provide a powerful and versatile platform for quantum computing,simulation, and metrology applications. The cornerstone technique for generating these cold, dense samples of molecular gasses is the magneto-optical trap (MOT). Conventional molecular MOTs use red-detuned light, limiting them to relatively high temperatures and low densities, leading to small spatial overlap and low loading efficiency...

Cavity-enabled real-time observation of individual atomic collisions

Arrays of individual neutral atoms represent a promising platform for quantum information processing due to their scalability, arbitrary connectivity, and long coherence times. These features are enabled in large part by the simple trapping and high-fidelity fluorescence imaging of individual atoms within tweezer traps. In our lab, we use strong dispersive coupling to a high-cooperativity...

Physicists arrange atoms in extremely close proximity

Proximity is key for many quantum phenomena, as interactions between atoms are stronger when the particles are close. In many quantum simulators, scientists arrange atoms as close together as possible to explore exotic states of matter and build new quantum materials. They typically do this by cooling the atoms to a stand-still, then using laser...

Technique could improve the sensitivity of quantum sensing devices

In quantum sensing, atomic-scale quantum systems are used to measure electromagnetic fields, as well as properties like rotation, acceleration, and distance, far more precisely than classical sensors can. The technology could enable devices that image the brain with unprecedented detail, for example, or air traffic control systems with precise positioning accuracy.
