Ultracold-atom quantum tunneling through single and double optical barriers

R Eid, A Hammond, L Lavoine, T Bourdel - Physical Review A, 2024 - APS
We realize textbook experiments on Bose-Einstein condensate tunneling through thin
repulsive potential barriers. In particular, we demonstrate atom tunneling though a single …

Wave operator representation of quantum and classical dynamics

G McCaul, DV Zhdanov, DI Bondar - Physical Review A, 2023 - APS
The choice of mathematical representation when describing physical systems is of great
