Shortcuts to adiabaticity in Fermi gases
Pengpeng Diao, Shujin Deng, Fang Li +4
Shortcuts to adiabaticity (STA) provide an alternative to adiabatic protocols to guide the dynamics of the system of interest without the requirement of slow driving. We report the…

Superadiabatic quantum friction suppression in finite-time thermodynamics
Shujin Deng, Aurélia Chenu, Pengpeng Diao +5
Optimal performance of thermal machines is reached by suppressing friction. Friction in quantum thermodynamics results from fast driving schemes that generate nonadiabatic excitati…

Observation of Dynamical Super Efimovian Expansion in a Unitary Fermi Gas
Shujin Deng, Pengpeng Diao, Fang Li +3
We report an observation of a dynamical super Efimovian expansion in a two-component strongly interacting Fermi gas by engineering time dependent external harmonic trap frequencies…
