Phase transitions: a wave that doesn’t propagate but spreads like tea in water
A new quantum phenomenon: a Nambu Goldstone mode that does not propagate, but rather diffuses.
How to observe a quantum wave packet in situ?
Researchers have successfully observed the free expansion of a quantum wave packet of a single atom in continuous space. Using a novel imaging technique that combines optical trapping and quantum gas microscopy, they tracked with unprecedented precision the spreading of the probability density associated with an atom released from its trap.
Certify the properties of N-body quantum states
A new theoretical approach to the N-body quantum problem has been developed, providing, for the first time, a rigorous estimate of the errors made by approximate solutions calculated through numerical simulations using traditional methods.
Quantum Hall effect in 4D
Researchers at LKB have created cold dysprosium atoms showing 4D quantum Hall effect behavior by utilizing synthetic dimensions ! This breakthrough opens new avenues in quantum physics beyond solid-state systems.
Cold-atom elevator
Published in Physical Review Letters, researchers from LKB and their colleagues have developed an ‘elevator’ for atoms, to connect quantum simulators to an atomic reservoir, paving the way for creating exotic quantum states and studying their transport properties.
