Comparative Study of Electric Tractor and Diesel Tractor [PDF]
IOP Conference Series: Materials Science and Engineering, 2021 Abstract The increase in population day-by-day causes a direct and indirect effect on country’s pollution and resources. These have adverse effects on the environment and contributes directly to climate change. A transition from an internal combustion engine to an electric vehicle is vital, since with a lot of motor and battery ...

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 ...

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
