Spin models are the prime example of simplified many-body Hamiltonians used to model complex, strongly correlated real-world materials. However, despite the simplified character of such models, their dynamics often cannot be simulated exactly on classical computers when the number of particles exceeds a few tens. For this reason, quantum simulation of spin Hamiltonians using the tools of atomic and molecular physics has become a...

Tunable two-dimensional arrays of single Rydberg atoms for realizing quantum Ising models
Spin models are the prime example of simplified many-body Hamiltonians used to model complex, strongly correlated real-world materials. However, despite the simplified character of such models, their dynamics often cannot be simulated exactly on classical computers when the number of particles exceeds a few tens.

Fully integrated wearable sensor arrays for multiplexed in situ perspiration analysis
Wearable sensor technologies are essential to the realization of personalized medicine through continuously monitoring an individual’s state of health. Sampling human sweat, which is rich in physiological information, could enable non-invasive monitoring. Previously reported sweat-based and other non-invasive biosensors either can only monitor a single analyte at a time or lack on-site signal processing circuitry and sensor calibration mechanisms for accurate analysis of the...
Planet X? Probably not, but ALMA telescope array’s readings stir up debate
An array of radio telescopes in Chile has picked up weird readings that appear to be coming from far-out objects – and that’s sparked a debate over whether they’re previously undetected worlds on the edge of our solar system, brown dwarfs,...
