Optimally robust shortcuts to population inversion in two-level quantum systems
A. Ruschhaupt, Xi Chen, D. Alonso +1
We examine the stability versus different types of perturbations of recently proposed shortcuts-to-adiabaticity to speed up the population inversion of a two-level quantum system.…
Transitionless quantum drivings for the harmonic oscillator
J. G. Muga, X. Chen, Ibáñez +2
Two methods to change a quantum harmonic oscillator frequency without transitions in a finite time are described and compared. The first method, a transitionless-tracking algorithm…
Fast optimal frictionless atom cooling in harmonic traps
Xi Chen, A. Ruschhaupt, S. Schmidt +3
A method is proposed to cool down atoms in a harmonic trap without phase-space compression as in a perfectly slow adiabatic expansion, i.e., keeping the populations of the instanta…
How Events Come Into Being: EEQT, Particle Tracks, Quantum Chaos, and Tunneling Time
Ph. Blanchard, A. Jadczyk, A. Ruschhaupt
In sections 1 and 2 we review Event Enhanced Quantum Theory (EEQT). In section 3 we discuss applications of EEQT to tunneling time, and compare its quantitative predictions with ot…
