Graph-based Semi-Supervised Learning via Maximum Discrimination
Nadav Katz, Ariel Jaffe
Semi-supervised learning (SSL) addresses the critical challenge of training accurate models when labeled data is scarce but unlabeled data is abundant. Graph-based SSL (GSSL) has e…
Measuring work in quantum many-body systems using a dynamical "work agent"
Cheolhee Han, Nadav Katz, Eran Sela
We consider a generic quantum many-body system initiated at thermal equilibrium and driven by an external parameter, and discuss the prospect for measuring the work done by the var…
Bogoliubov excitation spectrum in anharmonic traps
E Gershnabel, N Katz, E Rowen +1
We study the linearized Bogoliubov excitation spectrum of infinitely long anharmonically trapped Bose-Einstein condensates, with the aim of overcoming inhomogeneous broadening. We…
Splitting in the Excitation Spectrum of A Bose-Einstein Condensate Undergoing Strong Rabi Oscillations
E. Rowen, R. Ozeri, N. Katz +2
We report on a measurement of splitting in the excitation spectrum of a condensate driven by an optical travelling wave. Experimental results are compared to a numerical solution o…
Decoherence and dephasing in strongly driven colliding Bose-Einstein condensates
N. Katz, R. Ozeri, E. Rowen +2
We report on a series of measurements of decoherence and wavepacket dephasing between two colliding, strongly coupled, identical Bose-Einstein condensates. We measure, in the stron…
Bragg spectroscopy of the multi-branch Bogoliubov spectrum of elongated Bose-Einstein condensates
J. Steinhauer, N. Katz, R. Ozeri +3
We measure the response of an elongated Bose-Einstein condensate to a two-photon Bragg pulse. If the duration of the pulse is long, the total momentum transferred to the condensate…
