Journal ArticleDOI
New states of matter with fine-tuned interactions: quantum droplets and dipolar supersolids.
Fabian Böttcher,Jan-Niklas Schmidt,Jens Hertkorn,K. S. H. Ng,S. D. Graham,Mingyang Guo,Tim Langen,Tilman Pfau +7 more
TL;DR: In this paper, quantum fluctuations can stabilize Bose-Einstein condensates (BECs) against the mean field collapse and supersolid crystals formed from these droplets.
Journal ArticleDOI
New states of matter with fine-tuned interactions: quantum droplets and dipolar supersolids
Fabian Böttcher,Jan-Niklas Schmidt,Jens Hertkorn,K. S. H. Ng,S. D. Graham,Mingyang Guo,Tim Langen,Tilman Pfau +7 more
TL;DR: The fine-tuning of the interatomic interactions can lead to the emergence of two new states of matter: liquid-like selfbound quantum droplets and supersolid crystals formed from these droplets.
Journal ArticleDOI
Pattern formation in quantum ferrofluids: From supersolids to superglasses
Jens Hertkorn,Jan-Niklas Schmidt,Mingyang Guo,Fabian Böttcher,K. S. H. Ng,S. D. Graham,P. Uerlings,Tim Langen,Martin Zwierlein,Tilman Pfau +9 more
TL;DR: In this paper, the authors theoretically investigate the phase diagram of quantum ferrofluids in oblate trap geometries and find an even wider range of exotic states of matter.
Journal ArticleDOI
Roton Excitations in an Oblate Dipolar Quantum Gas.
Jan-Niklas Schmidt,Jens Hertkorn,Mingyang Guo,Fabian Böttcher,Markus A. Schmidt,K. S. H. Ng,S. D. Graham,Tim Langen,Martin Zwierlein,Tilman Pfau +9 more
TL;DR: In this article, the radial and angular roton excitations around a droplet crystallization transition in dipolar Bose-Einstein condensates are observed and in situ measurements are used to characterize the density fluctuations near this transition.
Journal ArticleDOI
Supersolidity in Two-Dimensional Trapped Dipolar Droplet Arrays.
Jens Hertkorn,Jan-Niklas Schmidt,Mingyang Guo,Fabian Böttcher,K. S. H. Ng,S. D. Graham,P. Uerlings,Hans Peter Büchler,Tim Langen,Martin Zwierlein,Tilman Pfau +10 more
TL;DR: In this paper, the ground states and spectrum of elementary excitations across the superfluid to droplet crystallization transition of an oblate dipolar Bose-Einstein condensate were theoretically investigated.
