Experimental study of tune-out wavelengths for spin-dependent optical lattice in 87Rb Bose–Einstein condensation

K Wen, Z Meng, L Wang, L Chen, L Huang, P Wang… - JOSA B, 2021 - opg.optica.org
We study the periodic potential of a one-dimensional optical lattice originating from a scalar
shift and vector shift by manipulating the lattice polarizations. The ac Stark shift of an optical …

Enhancing Kondo coupling in alkaline-earth-metal atomic gases with confinement-induced resonances in mixed dimensions

Y Cheng, R Zhang, P Zhang, H Zhai - Physical Review A, 2017 - APS
The Kondo effect describes the spin-exchange interaction between localized impurities and
itinerant fermions. The ultracold alkaline-earth atomic gas provides a natural platform for …

Confinement-induced resonances in anharmonic waveguides

SG Peng, H Hu, XJ Liu, PD Drummond - Physical Review A—Atomic, Molecular …, 2011 - APS
We develop the theory of anharmonic confinement-induced resonances (ACIRs). These are
caused by anharmonic excitation of the transverse motion of the center of mass (cm) of two …

Liberating Efimov physics from three dimensions

Y Nishida, S Tan - Few-Body Systems, 2011 - Springer
When two particles attract via a resonant short-range interaction, three particles always form
an infinite tower of bound states characterized by a discrete scaling symmetry. It has been …

Multi-impurity polarons in a dilute Bose–Einstein condensate

DH Santamore, E Timmermans - New Journal of Physics, 2011 - iopscience.iop.org
We describe the ground state of a large, dilute, neutral atom Bose–Einstein condensate
(BEC) doped with N strongly coupled mutually indistinguishable, bosonic neutral atoms …

Confinement-induced -wave resonances from -wave interactions

Y Nishida, S Tan - Physical Review A—Atomic, Molecular, and Optical …, 2010 - APS
We show that a purely s-wave interaction in three dimensions (3D) can induce higher partial-
wave resonances in mixed dimensions. We develop two-body scattering theories in all three …

Analytic harmonic approach to the N-body problem

JR Armstrong, NT Zinner, DV Fedorov… - Journal of Physics B …, 2011 - iopscience.iop.org
We consider an analytic way to make the interacting N-body problem tractable by using
harmonic oscillators in place of the relevant two-body interactions. The two-body terms of the …

Quantum Mixtures of Ultracold Atomic Gases

C Baroni, G Lamporesi, M Zaccanti - arXiv preprint arXiv:2405.14562, 2024 - arxiv.org
The combination of different kinds of ultracold gases constitutes a novel powerful
experimental framework for the investigation of a variety of physical problems. We illustrate …

Bloch oscillations of bosonic lattice polarons

F Grusdt, A Shashi, D Abanin, E Demler - Physical Review A, 2014 - APS
We consider a single-impurity atom confined to an optical lattice and immersed in a
homogeneous Bose-Einstein condensate (BEC). Interaction of the impurity with the phonon …

Continuous Faraday measurement of spin precession without light shifts

M Jasperse, MJ Kewming, SN Fischer, P Pakkiam… - Physical Review A, 2017 - APS
We describe a dispersive Faraday optical probe of atomic spin which performs a weak
measurement of spin projection of a quantum gas continuously for more than one second …
