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…

Relaxation to quantum equilibrium and the Born rule in Nelson's stochastic dynamics
Vincent Hardel, Paul-Antoine Hervieux, Giovanni Manfredi
Nelson's stochastic quantum mechanics provides an ideal arena to test how the Born rule is established from an initial probability distribution that is not identical to the square…
