Ultracold atoms dressed by light simulate gauge theories

Our modern understanding of the physical world is based on gauge theories: mathematical models from theoretical physics that describe the interactions between elementary particles (such as electrons or quarks) and explain ...

Microcavities as a sensor platform

Sensors are a pillar of the Internet of Things, providing the data to control all sorts of objects. Here, precision is essential, and this is where quantum technologies could make a difference. Researchers in Innsbruck and ...

Quantum particles: Pulled and compressed

Very recently, researchers led by Markus Aspelmeyer at the University of Vienna and Lukas Novotny at ETH Zurich cooled a glass nanoparticle into the quantum regime for the first time. To do this, the particle is deprived ...

A quantum of solid: A glass nanoparticle in the quantum regime

Researchers in Austria have used lasers to levitate and cool a glass nanoparticle into the quantum regime. Although it is trapped in a room-temperature environment, the particle's motion is solely governed by the laws of ...

A sound idea: A step towards quantum computing

A team at the University of Tsukuba studied a novel process for creating coherent lattice waves inside silicon crystals using ultrashort laser pulses. Using theoretical calculations combined with experimental results that ...
