Detecting atoms trapped in an optical lattice using a tapered optical nanofiber
T. Hennessy, Th. Busch
Optical detection of structures with dimensions smaller than an optical wavelength requires devices that work on scales beyond the diffraction limit. Here we present the possibilit…
Measurement of collective excitations in a spin-orbit-coupled Bose-Einstein condensate
M. A. Khamehchi, Yongping Zhang, Chris Hamner +2
We measure the collective excitation spectrum of a spin-orbit coupled Bose-Einstein condensate using Bragg spectroscopy. The spin-orbit coupling is generated by Raman dressing of a…
Quantum correlations and spatial localization in one-dimensional ultracold bosonic mixtures
M. A. García-March, B. Juliá-Díaz, G. E. Astrakharchik +3
We present the complete phase diagram for one-dimensional binary mixtures of bosonic ultracold atomic gases in a harmonic trap. We obtain exact results with direct numerical diagon…
Adiabatic potentials using multiple radio frequencies
T. Morgan, Th. Busch, T. Fernholz
Adiabatic radio frequency (RF) potentials are powerful tools for creating advanced trapping geometries for ultra-cold atoms. While the basic theory of RF trapping is well understoo…
Quenching small quantum gases: Genesis of the orthogonality catastrophe
Steve Campbell, Miguel Ángel García-March, Thomás Fogarty +1
We study the dynamics of two strongly interacting bosons with an additional impurity atom trapped in a harmonic potential. Using exact numerical diagonalization we are able to full…
Quantum reservoirs with ion chains
B. G. Taketani, T. Fogarty, E. Kajari +2
Ion chains are promising platforms for studying and simulating quantum reservoirs. One interesting feature is that their vibrational modes can mediate entanglement between two obje…
