Birth, life, and death of a dipolar supersolid
In the short time since the first observation of supersolid states of ultracold dipolar atoms, substantial progress has been made in understanding the zero-temperature phase diagram and low-energy excitations of these systems. Less is known, however, about their finite-temperature properties, particularly relevant for supersolids formed by cooling through direct evaporation.
In this new experimental work, we explore this realm by characterizing the evaporative formation and subsequent decay of a dipolar supersolid by combining high-resolution in-trap imaging with time-of-flight observables. As our atomic system cools towards quantum degeneracy, it first undergoes a transition from thermal gas to a crystalline state with the appearance of periodic density modulation. This is followed by a transition to a supersolid state with the emergence of long-range phase coherence. Further, we explore the role of temperature in the development of the modulated state.
Goodbye to Arno
After 5 productive years in the Dipolar Quantum Gas Group, Arno Trautmann is moving to the University of Tübingen as post-doc in the group of Professor Christian Groß. We wish you great success in your next adventure in physics

Goodbye to Daniel and Philipp
Farwell to Daniel Petter and Philipp Ilzhöfer, who obtained their PhD toward the end of 2020 and are now heading for new challanges. We wish you every success in your future life!
