Charged polarons and molecules in a Bose-Einstein Condensate
Esben Rohan Christensen, Arturo Camacho-Guardian, Georg M. Bruun
We investigate the properties a mobile ion immersed in a Bose-Einstein condensate (BEC) using different theoretical approaches. A coherent state variational ansatz predicts that th…
Self-bound droplet clusters in laser-driven Bose-Einstein condensates
Yong-Chang Zhang, Valentin Walther, Thomas Pohl
We investigate a two-dimensional Bose-Einstein condensate that is optically driven via a retro-reflecting mirror, forming a single optical feedback loop. This induces a peculiar ty…
Observation of Microcanonical Atom Number Fluctuations in a Bose-Einstein Condensate
M. B. Christensen, T. Vibel, A. J. Hilliard +6
Quantum systems are typically characterized by the inherent fluctuation of their physical observables. Despite this fundamental importance, the investigation of the fluctuations in…
Observation of a Lee-Huang-Yang Fluid
Thomas G. Skov, Magnus G. Skou, Nils B. Jørgensen +1
We observe monopole oscillations in a mixture of Bose-Einstein condensates, where the usually dominant mean-field interactions are canceled. In this case, the system is governed by…
Finite-range effects in the two-dimensional repulsive Fermi polaron
Raúl Bombín, Viktor Cikojević, Juan Sánchez-Baena +1
We study the repulsive Fermi polaron in a two-component, two-dimensional system of fermionic atoms inspired by the results of a recent experiment with Yb atoms [N. Darkwah…
Three identical bosons: Properties in non-integer dimensions and in external fields
E. Garrido, A. S. Jensen
Three-body systems that are continuously squeezed from a three-dimensional (3D) space into a two-dimensional (2D) space are investigated. Such a squeezing can be obtained by means…
Electromagnetically induced transparency with CuO excitons in the presence of phonon coupling
Valentin Walther, Peter Grünwald, Thomas Pohl
Highly excited Rydberg states of excitons in CuO semiconductors provide a promising approach to explore and control strong particle interactions in a solid-state environment. A…
Non-equilibrium quantum dynamics and formation of the Bose polaron
Magnus G. Skou, Thomas G. Skov, Nils B. Jørgensen +5
Advancing our understanding of non-equilibrium phenomena in quantum many-body systems remains among the greatest challenges in physics. Here, we report on the experimental observat…
Observing the emergence of a quantum phase transition -- shell by shell
Luca Bayha, Marvin Holten, Ralf Klemt +6
Many-body physics describes phenomena which cannot be understood looking at a systems' constituents alone. Striking manifestations are broken symmetry, phase transitions, and colle…
Mobile impurity in a Bose-Einstein condensate and the orthogonality catastrophe
Nils-Eric Guenther, Richard Schmidt, Georg M. Bruun +2
We analyze the properties of an impurity in a dilute Bose-Einstein condensate (BEC). First the quasiparticle residue of a static impurity in an ideal BEC is shown to vanish with in…
Simulation of XXZ Spin Models using Sideband Transitions in Trapped Bosonic Gases
Anjun Chu, Johannes Will, Jan Arlt +2
We theoretically propose and experimentally demonstrate the use of motional sidebands in a trapped ensemble of Rb atoms to engineer tunable long-range XXZ spin models. We be…
Detecting chiral pairing and topological superfluidity using circular dichroism
J. M. Midtgaard, Zhigang Wu, N. Goldman +1
Realising and probing topological superfluids is a key goal for fundamental science, with exciting technological promises. Here, we show that chiral pairing in a two-dim…
Superfluid flow of polaron polaritons above Landau's critical velocity
K. Knakkergaard Nielsen, A. Camacho-Guardian, G. M. Bruun +1
We develop a theory for the interaction of light with superfluid optical media, describing the motion of quantum impurities that are created and dragged through the liquid by propa…
Clusters in Separated Tubes of Tilted Dipoles
Jeremy R. Armstrong, Aksel S. Jensen, Artem G. Volosniev +1
A few-body cluster is a building block of a many-body system in a gas phase provided the temperature at most is of the order of the binding energy of this cluster. Here we illustra…
