Strongly dipolar molecular Bose-Einstein condensates: From few- to many-body physics
Andreas Schindewolf, Jens Hertkorn, Ian Stevenson +8
Recent advances in molecular cooling have enabled the realization of strongly dipolar Bose--Einstein condensates (BECs) of molecules, and BECs of many different molecular species m…
Microsecond-scale high-survival and number-resolved detection of ytterbium atom arrays
Alessandro Muzi Falconi, Riccardo Panza, Sara Sbernardori +5
Scalable atom-based quantum platforms for simulation, computing, and metrology require fast high-fidelity, low-loss imaging of individual atoms. Standard fluorescence detection met…
Josephson vortices and persistent current in a double-ring supersolid system
Malte Schubert, Koushik Mukherjee, Tilman Pfau +1
We theoretically investigate the properties of ultra-cold dipolar atoms in radially coupled, concentric annular traps created by a potential barrier. The non-rotating ground-state…
Optical response of the supersolid polaron
Laurent H. A. Simons, Ralf Klemt, Tilman Pfau +2
The ground-state properties of the supersolid polaron consisting of a neutral impurity immersed in a dipolar supersolid have recently been studied. Here, the optical response of an…
Decoupled sound and amplitude modes in trapped dipolar supersolids
Jens Hertkorn, Philipp Stürmer, Koushik Mukherjee +7
We theoretically investigate elementary excitations of dipolar quantum gases across the superfluid to supersolid phase transition in a toroidal trap. We show how decoupled first so…
Miscibility-Immiscibility transition of strongly interacting bosonic mixtures in optical lattices
Rukmani Bai, Soumik Bandyopadhyay
Interaction plays key role in the mixing properties of a multi-component system. The miscibility-immiscibility transition (MIT) in a weakly interacting mixture of Bose gases is pre…
In situ observation of chemistry in Rydberg molecules within a coherent solvent
Felix Engel, Shiva Kant Tiwari, Tilman Pfau +2
We often infer the state of systems in nature indirectly, for example, in high-energy physics by the interaction of particles with an ambient medium. We adapt this principle to ene…
Quantum state manipulation and cooling of ultracold molecules
Tim Langen, Giacomo Valtolina, Dajun Wang +1
An increasingly large variety of molecular species are being cooled down to low energies in recent years, and innovative ideas and powerful techniques continue to emerge to gain ev…
Kaleidoscopes of Hofstadter Butterflies and Aharonov-Bohm caging from -root topology in decorated square lattices
A. M. Marques, J. Mögerle, G. Pelegrí +3
Square-root topology describes models whose topological properties can be revealed upon squaring the Hamiltonian, which produces their respective parent topological insulators. Thi…
Quantum fluctuations in one-dimensional supersolids
Chris Bühler, Tobias Ilg, Hans Peter Büchler
In one-dimension, quantum fluctuations prevent the appearance of long-range order in a supersolid, and only quasi long-range order can survive. We derive this quantum critical beha…
Ground-state stability and excitation spectrum of a one-dimensional dipolar supersolid
Tobias Ilg, Hans Peter Büchler
We study the behavior of the excitation spectrum across the quantum phase transition from a superfluid to a supersolid phase of a dipolar Bose gas confined to a one-dimensional geo…
Making statistics work: a quantum engine in the BEC-BCS crossover
Jennifer Koch, Keerthy Menon, Eloisa Cuestas +5
Heat engines convert thermal energy into mechanical work both in the classical and quantum regimes. However, quantum theory offers genuine nonclassical forms of energy, different f…
Observation of confinement-induced resonances in a 3D lattice
Deborah Capecchi, Camilo Cantillano, Manfred J. Mark +6
We report on the observation of confinement-induced resonances for strong three-dimensional (3D) confinement in a lattice potential. Starting from a Mott-insulator state with predo…
Dipolar physics: A review of experiments with magnetic quantum gases
Lauriane Chomaz, Igor Ferrier-Barbut, Francesca Ferlaino +3
Since the achievement of quantum degeneracy in gases of chromium atoms in 2004, the experimental investigation of ultracold gases made of highly magnetic atoms has blossomed. The f…
Self-bound dipolar droplets and supersolids in molecular Bose-Einstein condensates
Matthias Schmidt, Lucas Lassablière, Goulven Quéméner +1
We numerically study the many-body physics of molecular Bose-Einstein condensates with strong dipole-dipole interactions. We observe the formation of self-bound droplets, and explo…
Quantum phases of dipolar bosons in multilayer optical lattice
Soumik Bandyopadhyay, Hrushikesh Sable, Deepak Gaur +3
We consider a minimal model to investigate the quantum phases of hardcore, polarized dipolar atoms confined in multilayer optical lattices. The model is a variant of the extended B…
Topological quantum critical points in the extended Bose-Hubbard model
Joana Fraxanet, Daniel González-Cuadra, Tilman Pfau +3
The combination of topology and quantum criticality can give rise to an exotic mix of counterintuitive effects. Here, we show that unexpected topological properties take place in a…

J. Hertkorn, J. -N. Schmidt, M. Guo +7
Pattern formation is a ubiquitous phenomenon observed in nonlinear and out-of-equilibrium systems. In equilibrium, quantum ferrofluids formed from ultracold atoms were recently sho…
