String breaking mechanism in a lattice Schwinger model simulator
Ying Liu, Wei-Yong Zhang, Zi-Hang Zhu +3
String breaking is a fundamental concept in gauge theories, describing the decay of a flux string connecting two charges through the production of particle-antiparticle pairs. This…

Probing false vacuum decay on a cold-atom gauge-theory quantum simulator
Zi-Hang Zhu, Ying Liu, Gianluca Lagnese +9
In the context of quantum electrodynamics, the decay of false vacuum leads to the production of electron-positron pair, a phenomenon known as the Schwinger effect. In practical exp…

Observation of counterflow superfluidity in a two-component Mott insulator
Yong-Guang Zheng, An Luo, Ying-Chao Shen +8
The counterflow superfluidity (CSF) was predicted two decades ago. Counterintuitively, while both components in the CSF have fluidity, their correlated counterflow currents cancel…
