Broken scale-invariance in time-dependent trapping potentials
Seyed Ebrahim Gharashi, D. Blume
The response of a cold atom gas with contact interactions to a smoothly varying external harmonic confinement in the non-adiabatic regime is studied. The time variation of the angu…
Tunneling dynamics of two interacting one-dimensional particles
Seyed Ebrahim Gharashi, D. Blume
We present one-dimensional simulation results for the cold atom tunneling experiments by the Heidelberg group [G. Zürn {\em{et al.}}, Phys. Rev. Lett. {\bf{108}}, 075303 (2012) and…
Energy and structural properties of -boson clusters attached to three-body Efimov states: Two-body zero-range interactions and the role of the three-body regulator
Yangqian Yan, D. Blume
The low-energy spectrum of -boson clusters with pairwise zero-range interactions is believed to be governed by a three-body parameter. We study the ground state of -boson clu…
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…
Generalized Efimov scenario for heavy-light mixtures
D. Blume, Yangqian Yan
Motivated by recent experimental investigations of Cs-Cs-Li Efimov resonances, this work theoretically investigates the few-body properties of non-interacting identical heavy…
Temperature-dependence of small harmonically trapped atom systems with Bose, Fermi and Boltzmann statistics
Yangqian Yan, D. Blume
While the zero-temperature properties of harmonically trapped cold few-atom systems have been discussed fairly extensively over the past decade, much less is known about the finite…
