Shortcut to adiabaticity in the Lipkin-Meshkov-Glick model.

We study transitionless quantum driving in an infinite-range many-body system described by the Lipkin-Meshkov-Glick model. Despite the correlation length being always infinite the closing of the gap at the critical point makes the driving Hamiltonian of increasing complexity also in this case. To this aim we develop a hybrid strategy combining a shortcut to adiabaticity and optimal control that...

Shortcut To Adiabaticity for an Anisotropic 2D Bose Gas Containing Defects

We present a Shortcut To Adiabaticity (STA) protocol applicable to two–dimensional weakly– interacting Bose gases containing defects such as vortices or solitons. Our protocol relies on a new class of exact scaling solutions to the Gross–Pitaevskii equation applied to the 2D Bose gas in the presence of anisotropic time–dependent harmonic traps. It connects stationary states corresponding to ini...

Fast optimal frictionless atom cooling in harmonic traps: shortcut to adiabaticity.

A method is proposed to cool down atoms in a harmonic trap without phase-space compression as in a perfectly slow adiabatic expansion, i.e., keeping the same populations of instantaneous levels in the initial and final traps, but in a much shorter time. This may require that the harmonic trap become transiently an expulsive parabolic potential. The cooling times achieved are shorter than those ...

Testing quantum adiabaticity with quench echo

Adiabaticity of quantum evolution is important in many settings; one example is adiabatic quantum computation (AQC). Nevertheless, to date, there is no effective method available for testing the adiabaticity of the evolution for the case where the eigenenergies of the driven Hamiltonian are not known. We propose a simple method for checking the adiabaticity of a quantum process for an arbitrary...
