Synthesizing arbitrary dispersion relations in a modulated tilted optical lattice
Jean Claude Garreau, Véronique Zehnlé
Dispersion relations are fundamental characteristics of the dynamics of quantum and wave systems. In this work we introduce a simple technique to generate arbitrary dispersion rela…
Analog quantum simulation of the spinor-four Dirac equation with an artificial gauge field
Jean Claude Garreau, Véronique Zehnlé
A two-dimensional spatially and temporally modulated Wannier-Stark system of ultracold atoms in optical lattices is shown to mimic the behavior of a Dirac particle. Suitable additi…
Simulating Dirac models with ultracold atoms in optical lattices
Jean Claude Garreau, Véronique Zehnlé
We present a general model allowing "quantum simulation" of one-dimensional Dirac models with 2- and 4-component spinors using ultracold atoms in driven 1D tilted optical latices.…
A quantum motor: directed wavepacket motion in an optical lattice
Quentin Thommen, Jean Claude Garreau, Véronique Zehnlé
We propose a method for arbitrary manipulations of a quantum wavepacket in an optical lattice by a suitable modulation of the lattice amplitude. A theoretical model allows to deter…
Atomic Dipole Traps with Amplified Spontaneous Emission: A Proposal
Jean-François Clément, Véronique Zehnlé, Jean Claude Garreau +1
We propose what we believe to be a novel type of optical source for ultra-cold atomic Far Off-Resonance optical-dipole Traps (FORTs). The source is based on an Erbium Amplified Spo…
Suppression of decoherence effects in the quantum kicked rotor
Maxence Lepers, Véronique Zehnlé, Jean Claude Garreau
We describe a method allowing transient suppression of decoherence effects on the atom-optics realization of the kicked rotor. The system is prepared in an initial state with a mom…
Doppler cooling to the recoil limit using sharp atomic transitions
Véronique Zehnlé, Jean Claude Garreau
In this paper, we develop an analytical approach to Doppler cooling of atoms by one- or two-photon transitions when the natural width of the excited level is so small that the proc…
Continuous-wave Doppler-cooling of hydrogen atoms with two-photon transitions
Véronique Zehnlé, Jean Claude Garreau
We propose and analyze the possibility of performing two-photon continuous-wave Doppler-cooling of hydrogen atoms using the 1S-2S transition. "Quenching" of the 2S level (by coupli…
