Following Franck Wilczek’s proposal of a new dynamical phase dubbed time crystal, discrete or Floquet time crystals have been observed in periodically...

Ultracold bosonic atoms filled into the second Bloch band of a hexagonal optical lattice made of three interfering laser beams can form intriguing...

A periodically driven open three-level Dicke model is realized by resonantly shaking the pump field in an atom-cavity system. As an unambiguous...

For the first time, a fermionic quantum gas of neutral atoms is loaded to selected higher Bloch bands of an optical lattice. Extreme band lifetimes...

Similarly, as the spontaneous breaking of translation symmetry can lead to crystallisation in space, a related phenomenon can occur with respect to...

Single atoms prepared in an excited state randomly return to the ground state with a probability approaching unity with exponential time dependence...

Superconductivity is a highly useful functional property of certain materials, which unfortunately requires extremely low temperatures. In the...

Bloch oscillations are a paradigm of coherent wave dynamics in periodic potentials. While in electronic lattice gases Bloch oscillations are covered...

Most many-body quantum states in nature may be categorized in terms of broken symmetries. Often it is the translational symmetry that is broken, for...
