High Frequency Sound in a Unitary Fermi Gas
C. C. N. Kuhn, S. Hoinka, I. Herrera +4
We present an experimental and theoretical study of the phonon mode in a unitary Fermi gas. Using two-photon Bragg spectroscopy, we measure excitation spectra at a momentum of appr…
Quantum phases of two-component bosons on the Harper-Hofstadter ladder
Jian-Dong Chen, Hong-Hao Tu, Ying-Hai Wu +1
We study two-component bosons on the Harper-Hofstadter model with two legs. The synthetic magnetic fields for the two types of bosons point to either the same direction or opposite…
Emergent ballistic transport of Bose-Fermi mixtures in one dimension
Sheng Wang, Xiangguo Yin, Yang-Yang Chen +2
The degenerate Bose-Fermi (BF) mixtures in one dimension present a novel realization of two decoupled Luttinger liquids with bosonic and fermionic degrees of freedom at low tempera…
Emergence of the Unconventional Type-II Nambu-Goldstone Modes with Topological Origin in Bose Superfluids
Jian-Song Pan, W. Vincent Liu, Xiong-Jun Liu
The Nambu-Goldstone (NG) modes in a nonrelativistic system can be classified into two types from their characteristic features: being of either an odd (type I) or an even (type II)…
Localization driven superradiant instability
Honghao Yin, Jie Hu, An-Chun Ji +3
The prominent Dicke superradiant phase arises from coupling an ensemble of atoms to cavity optical field when external optical pumping exceeds a threshold strength. Here we report…
Many-Body Echo
Yang-Yang Chen, Pengfei Zhang, Wei Zheng +2
In this letter we propose a protocol to reverse a quantum many-body dynamical process. We name it "many-body echo" because the underlying physics is closely related to the spin ech…
Polariton dynamics in strongly interacting quantum many-body systems
A. Camacho-Guardian, K. Knakkergaard Nielsen, T. Pohl +1
We develop a theory for light propagating in an atomic Bose-Einstein condensate in the presence of strong interactions. The resulting many-body correlations are shown to have profo…
Strong interactions and bi-excitons in a polariton mixture
M. A. Bastarrachea-Magnani, A. Camacho-Guardian, M. Wouters +1
We develop a many-body theory for the properties of exciton-polaritons interacting strongly with a Bose-Einstein condensate (BEC) of exciton-polaritons in another spin state. Inter…
Spontaneous formation of polar superfluid droplets in a p-wave interacting Bose gas
Zehan Li, Jian-Song Pan, W. Vincent Liu
We study the quantum fluctuations in the condensates of a mixture of bosonic atoms and molecules with interspecies p-wave interaction. Our analysis shows that the quantum phase of…
Topological Classification of Excitations in Quadratic Bosonic Systems
Zixian Zhou, Liang-Liang Wan, Zhi-Fang Xu
We investigate the topological classification of excitations in quadratic bosonic systems with an excitation band gap. Time-reversal, charge-conjugation, and parity symmetries in b…
Emergent topology and symmetry-breaking order in correlated quench dynamics
Long Zhang, Lin Zhang, Ying Hu +2
Quenching a quantum system involves three basic ingredients: the initial phase, the post-quench target phase, and the non-equilibrium dynamics which carries the information of the…
