Majorana edge state in a number-conserving Fermi gas with tunable p-wave interaction
X. Y. Yin, Tin-Lun Ho, Xiaoling Cui
The remarkable properties and potential applications of Majorana fermions have led to considerable efforts in recent years to realize topological matters that host these excitation…
Energy Cascade in Quantum Gases
Tin-Lun Ho, X. Y. Yin
Energy cascade is ubiquitous in systems far from equilibrium. Facilitated by particle interactions and external forces, it can lead to highly complex phenomena like fully developed…
Dynamics of small trapped one-dimensional Fermi gas under oscillating magnetic fields
X. Y. Yin, Yangqian Yan, D. Hudson Smith
Deterministic preparation of an ultracold harmonically trapped one-dimensional Fermi gas consisting of a few fermions has been realized by the Heidelberg group. Using Floquet forma…
One-dimensional Fermi gas with a single impurity in a harmonic trap: Perturbative description of the upper branch
Seyed Ebrahim Gharashi, X. Y. Yin, Yangqian Yan +1
The transition from "few to many" has recently been probed experimentally in an ultra cold harmonically confined one-dimensional lithium gas, in which a single impurity atom intera…
Universal and non-universal effective -body interactions for ultracold harmonically-trapped few-atom systems
X. Y. Yin, D. Blume, P. R. Johnson +1
We derive the ground-state energy for a small number of ultracold atoms in an isotropic harmonic trap using effective quantum field theory (EFT). Atoms are assumed to interact thro…
Energy spectrum of a harmonically trapped two-atom system with spin-orbit coupling
Q. Guan, X. Y. Yin, S. E. Gharashi +1
Ultracold atomic gases provide a novel platform with which to study spin-orbit coupling, a mechanism that plays a central role in the nuclear shell model, atomic fine structure and…
Harmonically trapped two-atom systems: Interplay of short-range s-wave interaction and spin-orbit coupling
X. Y. Yin, S. Gopalakrishnan, D. Blume
The coupling between the spin degrees of freedom and the orbital angular momentum has a profound effect on the properties of nuclei, atoms and condensed matter systems. Recently, s…
Molecular branch of a small highly-elongated Fermi gas with an impurity: Full three-dimensional versus effective one-dimensional description
S. E. Gharashi, X. Y. Yin, D. Blume
We consider an impurity immersed in a small Fermi gas under highly-elongated harmonic confinement. The impurity interacts with the atoms of the Fermi gas through an isotropic short…
Small two-component Fermi gases in a cubic box with periodic boundary conditions
X. Y. Yin, D. Blume
The properties of two-component Fermi gases become universal if the interspecies s-wave scattering length and the average interparticle spacing are much larger than the range…
Occupation numbers of the harmonically trapped few-boson system
K. M. Daily, X. Y. Yin, D. Blume
We consider a harmonically trapped dilute -boson system described by a low-energy Hamiltonian with pairwise interactions. We determine the condensate fraction, defined in terms…
