Tractor atom interferometry [PDF]
Physical Review A, 2021 We propose a tractor atom interferometer (TAI) based on three-dimensional (3D) confinement and transport of split atomic wavefunction components in potential wells that follow programmed paths. The paths are programmed to split and recombine atomic wavefunctions at well-defined space-time points, guaranteeing closure of the interferometer ...

Scientific Reports, 2023 Agricultural tractors often lose contact and recollide with the ground surface while driving on narrow paddy fields and bumpy farm roads owing to excessive vibrations. These nonlinear impact dynamics can cause chaotic vibrations during tractor operation.

Physical Review Letters, 2014 Negative radiation forces act opposite to the direction of propagation, or net momentum, of a beam but have previously been challenging to definitively demonstrate. We report an experimental acoustic tractor beam generated by an ultrasonic array operating on macroscopic targets (>1 cm) to demonstrate the negative radiation forces and to map out regimes

A study of the output characteristics of electric fuel pumps during artificial fault simulation [PDF]
FME Transactions, 2021 The electric fuel pump (EFP) is one of the potential sources of fuel system failures. According to various data, the fuel system accounts for 25...50% of all failures.
