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
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
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 …

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 …
