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…
Friction-free quantum machines
Adolfo del Campo, Aurélia Chenu, Shujin Deng +1
The operation of a quantum heat engine in finite time generally faces a trade-off between efficiency and power. Using shortcuts to adiabaticity (STA), this trade off can be avoided…
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…
Shortcuts to adiabaticity in the strongly-coupled regime: nonadiabatic control of a unitary Fermi gas
Shujin Deng, Pengpeng Diao, Qianli Yu +2
Coherent control of complex quantum systems is a fundamental requirement in quantum information processing and engineering. Recently developed notion of shortcut to adiabaticity (S…
Observation of the Efimovian Expansion in Scale Invariant Fermi Gases
Shujin Deng, Zhe-Yu Shi, Pengpeng Diao +4
Scale invariance emerges and plays an important role in strongly correlated many-body systems such as critical regimes nearby phase transitions and the unitary Fermi gases. Discret…
All-Optical Production of quantum degeneracy and molecular BEC of Li
Shujing Deng, Pengpeng Diao, Qianli Yu +1
We achieve a highly degenerate and strongly interacting Fermi gas in a mixture of the two lowest hyperfine states of Li by direct evaporative cooling in a high power crossed op…
