Fast quasiadiabatic dynamics
(2015-10-07)
We work out the theory and applications of a fast quasiadiabatic approach to speed up slow adiabatic manipulations of quantum systems by driving a control parameter as near to the adiabatic limit as possible over the entire ...
Fast driving between arbitrary states of a quantum particle by trap deformation
(2016-12-22)
By performing a slow adiabatic change between two traps of a quantum particle, it is possible to transform an eigenstate of the original trap into the corresponding eigenstate of the final trap. If no level crossings are ...
Fast atom transport and launching in a nonrigid trap
(Springer Nature, 2017-07-18)
We study the shuttling of an atom in a trap with controllable position and frequency. Using invariant-based inverse engineering, protocols in which the trap is simultaneously displaced and expanded are proposed to speed ...
Shortcuts to adiabaticity: concepts, methods, and applications
(2019-10-24)
Shortcuts to adiabaticity (STA) are fast routes to the final results of slow, adiabatic changes of the controlling parameters of a system. The shortcuts are designed by a set of analytical and numerical methods suitable ...
Shortcuts to adiabaticity in optical waveguides using fast quasiadiabatic dynamics
(Optica Publishing Group, 2017-01-03)
We propose a fast quasiadiabatic approach to the design of optical waveguide devices. This approach distributes the system adiabaticity homogeneously over the device length, thus providing a shortcut to adiabaticity at a ...
