Event details

In quantum physics, adiabatic processes keep constant the populations in the instantaneous eigenbasis of a time-dependent Hamiltonian. They are very useful to prepare and manipulate states, but take typically a long time. This is often problematic because decoherence and noise may spoil the desired final state, or because some applications require many repetitions. The aim of this talk is to give an overview of the so-called “Shortcuts to adiabaticity” protocols that are alternative fast processes which reproduce the same final populations, or even the same final state, as the adiabatic process in a finite, shorter time. Since adiabatic processes are ubiquitous, the shortcuts span a broad range of applications in atomic, molecular, and optical physics, such as fast transport of ions or neutral atoms, internal population control, and state preparation (for nuclear magnetic resonance or quantum information), cold atom expansions and other manipulations, cooling cycles, wave-packet splitting, and many-body state engineering or correlations microscopy.
