Advanced Quantum Technologies, Volume 3, Issue 11, November 2020., 2020 The properties of an optical dipole trap for single atoms when focusing the trapping beam from full solid angle with a deep parabolic mirror are described. The calculations yield favorable trap characteristics, which could prove to be beneficial for light–matter‐interaction experiments with neutral atoms and applications in quantum technology ...

Cold Molecule Spectroscopy for Constraining the Evolution of the Fine Structure Constant [PDF]
, 2006 We report precise measurements of ground-state, $\lambda$-doublet microwave transitions in the hydroxyl radical molecule (OH). Utilizing slow, cold molecules produced by a Stark decelerator we have improved over the precision of the previous best ...

Sisyphus Optical Lattice Decelerator [PDF]
, 2018 We experimentally demonstrate a variation on a Sisyphus cooling technique that was proposed for cooling antihydrogen. In our implementation, atoms are selectively excited to an electronic state whose energy is spatially modulated by an optical lattice ...

Optimizing the Stark-decelerator beamline for the trapping of cold molecules using evolutionary strategies [PDF]
, 2006 We demonstrate feedback control optimization for the Stark deceleration and trapping of neutral polar molecules using evolutionary strategies. In a Stark-decelerator beamline pulsed electric fields are used to decelerate OH radicals and subsequently ...

Simultaneous Zeeman deceleration of polyatomic free radical with lithium atoms [PDF]
Frontiers of Physics, 2020 Chemistry in the ultracold regime enables fully quantum-controlled interactions between atoms and molecules, leading to the discovery of the hidden mechanisms in chemical reactions which are usually curtained by thermal averaging in the high temperature. Recently a couple of diatomic molecules have been cooled to ultracold regime based on laser cooling

IET Cyber-Physical Systems: Theory &Applications, Volume 4, Issue 2, Page 128-138, June 2019., 2019 Cyber defence mechanism is started with modelling the accurate car‐following behaviour including cyber attack. The creation of finest models made the path of control action easier. The connection between the vehicles is mathematically formulated with the help of car‐following behaviour, incorporating the derived acceleration function from the cruise ...
