Morphology of three-body quantum states from machine learning
David Huber, Oleksandr V. Marchukov, Hans-Werner Hammer +1
The relative motion of three impenetrable particles on a ring, in our case two identical fermions and one impurity, is isomorphic to a triangular quantum billiard. Depending on the…
Interplay between friction and spin-orbit coupling as a source of spin polarization
Artem G. Volosniev, Hen Alpern, Yossi Paltiel +3
We study an effective one-dimensional quantum model that includes friction and spin-orbit coupling (SOC), and show that the model exhibits spin polarization when both terms are fin…
Shape of a sound wave in a weakly-perturbed Bose gas
Oleksandr V. Marchukov, Artem G. Volosniev
We employ the Gross-Pitaevskii equation to study acoustic emission generated in a uniform Bose gas by a static impurity. The impurity excites a sound-wave packet, which propagates…
Filtering Spins by Scattering from a Lattice of Point Magnets
Areg Ghazaryan, Mikhail Lemeshko, Artem G. Volosniev
Nature creates electrons with two values of the spin projection quantum number. In certain applications, it is important to filter electrons with one spin projection from the rest.…
Engineering momentum profiles of cold-atom beams
D Hudson Smith, Artem G Volosniev
We describe a procedure for engineering beams of cold atoms by selectively draining particles from a trapped gas based on momenta. Atoms escape through a filter potential that only…
Temperature dependence of an Efimov resonance in
Lars J. Wacker, Nils B. Jørgensen, Kristoffer T. Skalmstang +3
Ultracold atomic gases are an important testing ground for understanding few-body physics. In particular, these systems enable a detailed study of the Efimov effect. We use ultraco…
