Optimal Tracking of Distributed Heavy Hitters and Quantiles
Ke Yi, Qin Zhang
We consider the the problem of tracking heavy hitters and quantiles in the distributed streaming model. The heavy hitters and quantiles are two important statistics for characteriz…
Hot electron mediated desorption rates calculated from excited state potential energy surfaces
Thomas Olsen, Jeppe Gavnholt, Jakob Schiøtz
We present a model for Desorption Induce by (Multiple) Electronic Transitions (DIET/DIMET) based on potential energy surfaces calculated with the Delta Self-Consistent Field extens…
Spin squeezing of atomic ensembles by multi-colour quantum non-demolition measurements
M. Saffman, D. Oblak, J. Appel +1
We analyze the creation of spin squeezed atomic ensembles by simultaneous dispersive interactions with several optical frequencies. A judicious choice of optical parameters enables…
Delta Self-Consistent Field as a method to obtain potential energy surfaces of excited molecules on surfaces
Jeppe Gavnholt, Thomas Olsen, Mads Engelund +1
We present a modification of the SCF method of calculating energies of excited states, in order to make it applicable to resonance calculations of molecules adsorbed on metal su…
Echo Spectroscopy of Atomic Dynamics in a Gaussian Trap via Phase Imprints
Daniel Oblak, Juergen Appel, Patrick Windpassinger +3
We report on the collapse and revival of Ramsey fringe visibility when a spatially dependent phase is imprinted in the coherences of a trapped ensemble of two-level atoms. The phas…
Loading of large ion Coulomb crystals into a linear Paul trap incorporating an optical cavity for cavity QED studies
P. Herskind, A. Dantan, M. B. Langkilde-Lauesen +3
We report on the loading of large ion Coulomb crystals into a linear Paul trap incorporating a high-Finesse optical cavity (F~3200). We show that, even though the 3-mm diameter die…
