This research details how resonant lattice driving manipulates Bose-Einstein condensates in double-well potentials to precisely control quantum particle streams. The findings reveal that moderate asymmetry between potential wells unexpectedly enhances emission rates, offering new parameters for optimizing atomtronic devices and quantum simulations. These insights advance the fundamental understanding of many-body transport dynamics essential for next-generation quantum hardware design.

How Lattice Driving Shapes Quantum Particle Streams

Quantum ZeitgeistJuly 31, 20264 min read

Resonant lattice driving of a Bose-Einstein condensate in a double-well potential creates controlled particle jets, with emission rates influenced by well asymmetry and hopping amplitude.

Researchers at Nanjing University of Posts and Telecommunications and Nanhang Jincheng College have demonstrated precise control over the emission of particles from a Bose-Einstein condensate trapped within a specifically structured, one-dimensional lattice. Z. Li, Basic Teaching Department, Nanhang Jincheng College, Nanjing 211156, China, and L. Q. Lai, School of Science, Nanjing University of Posts and Telecommunications, Nanjing 210023, China, conducted the work, investigating how particles are emitted when interatomic interactions are…
