SFB 925Light induced dynamics and control of correlated quantum systems

Scientists from the University of Hamburg have pointed out how to create a time crystal in an intriguing class of materials, the high-temperature superconductors. They propose to drive these superconducting materials into a time crystalline state by inducing Higgs excitations via light. The work is reported in the journal...

Trapping of ultracold bosonic atoms in a one-dimensional double-well potential constitutes a prototype system for the investigations of the tunneling dynamics. Such a system represents a bosonic Josephson junction (BJJ), an atomic analogy of the Josephson effect initially predicted for a Cooper pair tunneling through two...

Zero electrical resistance at room temperature? A material with this property, i.e. a room temperature superconductor, could revolutionize power distribution. Scientists from Universität Hamburg and the Cluster of Excellence "CUI: Advanced Imaging of Matter" have succeeded in observing strong evidence of superfluidity in a...
