They can be formed with the help of a Feshbach resonance...8 June 2022|ILP HemmerichObservation of a continuous time crystalPhoto: AG HemmerichFollowing Franck Wilczek’s proposal of a new dynamical phase dubbed time crystal, discrete or Floquet time crystals have been observed in periodically...11 August 2021|ILP HemmerichUltracold atoms spontaneously set into superfluid rotationPhoto: AG HemmerichUltracold bosonic atoms filled into the second Bloch band of a hexagonal optical lattice made of three interfering laser beams can form intriguing...11 August 2021|ILP HemmerichRealization of a Periodically Driven Open Three-Level Dicke ModelPhoto: AG HemmerichA periodically driven open three-level Dicke model is realized by resonantly shaking the pump field in an atom-cavity system. As an unambiguous...20 May 2021|ILP HemmerichShaking up fermions into higher Bloch bandsPhoto: AG HemmerichFor the first time, a fermionic quantum gas of neutral atoms is loaded to selected higher Bloch bands of an optical lattice. Extreme band lifetimes...15 December 2020|ILP HemmerichObservation of a dissipative time crystalPhoto: AG HemmerichSimilarly, as the spontaneous breaking of translation symmetry can lead to crystallisation in space, a related phenomenon can occur with respect to...3 September 2019|ILP HemmerichSuperradiant Calcium laserPhoto: AG HemmerichSingle atoms prepared in an excited state randomly return to the ground state with a probability approaching unity with exponential time dependence...11 October 2018|ILP HemmerichEnforcing lockstep by shakingPhoto: AG HemmerichSuperconductivity is a highly useful functional property of certain materials, which unfortunately requires extremely low temperatures. In the...29 November 2016|ILP HemmerichTaking a peek at Bloch oscillationsPhoto: AG HemmerichBloch oscillations are a paradigm of coherent wave dynamics in periodic potentials. While in electronic lattice gases Bloch oscillations are covered...11 October 2016|ILP HemmerichInteraction-driven topological excitations in optical lattices with bosonsPhoto: AG HemmerichMost many-body quantum states in nature may be categorized in terms of broken symmetries. Often it is the translational symmetry that is broken, for...Show all news
