Adiabatic critical quantum metrology cannot reach the Heisenberg limit even when shortcuts to adiabaticity are applied
Karol Gietka, Friederike Metz, Tim Keller +1
We show that the quantum Fisher information attained in an adiabatic approach to critical quantum metrology cannot lead to the Heisenberg limit of precision and therefore regular q…
A Feshbach engine in the Thomas-Fermi regime
Tim Keller, Thomás Fogarty, Jing Li +1
Bose-Einstein condensates can be used to produce work by tuning the strength of the interparticle interactions with the help of Feshbach resonances. In inhomogeneous potentials, th…
Effects of coherence on quantum speed limits and shortcuts to adiabaticity in many-particle systems
Tian-Niu Xu, Jing Li, Thomas Busch +2
We discuss the effects of many-body coherence on the speed of evolution of ultracold atomic gases and the relation to quantum speed limits. Our approach is focused on two related s…
Driving interactions efficiently in a composite few-body system
Alan Kahan, Thomás Fogarty, Jing Li +1
We study how to efficiently control an interacting few-body system consisting of three harmonically trapped bosons. Specifically we investigate the process of modulating the interp…
Fast control of interactions in an ultracold two atom system: Managing correlations and irreversibility
Thomás Fogarty, Lewis Ruks, Jing Li +1
We design and explore a shortcut to adiabaticity (STA) for changing the interaction strength between two ultracold, harmonically trapped bosons. Starting from initially uncorrelate…
An efficient non-linear Feshbach engine
Jing Li, Thomás Fogarty, Steve Campbell +2
We investigate a thermodynamic cycle using a Bose-Einstein condensate with nonlinear interactions as the working medium. Exploiting Feshbach resonances to change the interaction st…
