Optimal Quantum Feshbach Engines
Aaron Wandhammer, Vincent Hardel, Paul-Antoine Hervieux +1
We develop an optimization framework for high-efficiency quantum cycles implemented with a trapped Bose-Einstein condensate, whose control parameters are the trap stiffness and the…
Shortcuts to adiabaticity in harmonic traps: a quantum-classical analog
Vincent Hardel, Giovanni Manfredi, Paul-Antoine Hervieux +1
We present a new technique for efficiently transitioning a quantum system from an initial to a final stationary state in less time than is required by an adiabatic (quasi-static) p…
Bose-Einstein condensation of positronium: modification of the s-wave scattering length below the critical temperature
O. Morandi, P. -A. Hervieux, G. Manfredi
The production of a Bose-Einstein condensate made of positronium may be feasible in the near future. Below the condensation temperature, the positronium collision process is modifi…
Fidelity decay in trapped Bose-Einstein condensates
G. Manfredi, P. -A. Hervieux
The quantum coherence of a Bose-Einstein condensate is studied using the concept of quantum fidelity (Loschmidt echo). The condensate is confined in an elongated anharmonic trap an…
