Interference effects in two-photon ATI by multiple orders high harmonics with random or locked phases
Eric Cormier, Anna Sanpera, Maciej Lewenstein +1
We numerically study 2-photon processes using a set of harmonics from a Ti:Sapphire laser and in particular interference effects in the Above Threshold Ionization spectra. We compa…
Dynamical Cooling of Trapped Gases I: One Atom Problem
Luis Santos, Maciej Lewenstein
We study the laser cooling of one atom in an harmonic trap beyond the Lamb-Dicke regime. By using sequences of laser pulses of different detunings we show that the atom can be conf…
On the volume of the set of mixed entangled states
Karol Zyczkowski, Pawel Horodecki, Anna Sanpera +1
A natural measure in the space of density matrices describing N-dimensional quantum systems is proposed. We study the probability P that a quantum state chosen randomly with respec…
