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…
Intertwined Space-Time Symmetry, Orbital Magnetism and Dynamical Berry Curvature in a Circularly Shaken Optical Lattice
Hua Chen, W. Vincent Liu
We study the circular shaking of a two dimensional optical lattice, which is essentially a (2+1) dimensional space-time lattice exhibiting periodicities in both spatial and tempora…
Squeezing-induced Topological Gap Opening on Bosonic Bogoliubov Excitations
Liang-Liang Wan, Zixian Zhou, Zhi-Fang Xu
We investigate the role of squeezing interaction in inducing topological Bogoliubov excitations of a bosonic system. We introduce a squeezing transformation which is capable of red…
Laser Control of Singlet-Pairing Process in an Ultracold Spinor Mixture
Jianwen Jie, Yonghong Yu, Dajun Wang +1
In the mixture of ultracold spin-1 atoms of two different species A and B (e.g., Na (A) and Rb (B)), inter-species singlet-pairing process ${\rm A}_{+1}+{\rm B}_{-1}\…
Dynamical Kosterlitz-Thouless Theory for Two-Dimensional Ultracold Atomic Gases
Zhigang Wu, Shizhong Zhang, Hui Zhai
In this letter we develop a theory for the first and second sound in a two-dimensional atomic superfluid across the superfluid transition based on the dynamic Koterlitz-Thouless th…
Universal relations for hybridized - and -wave interactions from spin-orbital coupling
Fang Qin, Pengfei Zhang
In this work, we study the universal relations for one-dimensional spin-orbital-coupled fermions near both - and -wave resonances using effective field theory. Since the spin…
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…
Unified theory to characterize Floquet topological phases by quench dynamics
Long Zhang, Lin Zhang, Xiong-Jun Liu
The conventional characterization of periodically driven systems usually necessitates the time-domain information beyond Floquet bands, hence lacking universal and direct schemes o…
Fast scrambling without appealing to holographic duality
Zehan Li, Sayan Choudhury, W. Vincent Liu
Motivated by the question of whether all fast scramblers are holographically dual to quantum gravity, we study the dynamics of a non-integrable spin chain model composed of two ing…
Large-momentun tail of one-dimensional Fermi gases with spin-orbit coupling
Fang Qin, Pengfei Zhang, Peng-Lu Zhao
We study the contacts, large-momentum tail, radio-frequency spectroscopy, and some other universal relations for an ultracold one-dimensional (1D) two-component Fermi gas with spin…
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…
