A C0(_2) laser lattice experiment for cold atoms [PDF]

open access: yes, 2007
This thesis presents work on a laser cooling experiment designed for trapping Rb atoms in a CO(_2) laser optical trap. Some emphasis is placed on experimental features designed to allow the future implementation of a neutral atom quantum computation ...

Boltzmann equation simulation for a trapped Fermi gas of atoms

open access: yes, 2012
The dynamics of an interacting Fermi gas of atoms at sufficiently high temperatures can be efficiently studied via a numerical simulation of the Boltzmann equation. In this paper, we describe in detail the setup we used recently to study the oscillations

The quantum Zeno and anti-Zeno effects with strong system-environment coupling

open access: yesScientific Reports, 2017
To date, studies of the quantum Zeno and anti-Zeno effects focus on quantum systems that are weakly interacting with their environment. In this paper, we investigate what happens to a quantum system under the action of repeated measurements if the ...

Quantum simulation of expanding space–time with tunnel-coupled condensates

open access: yesNew Journal of Physics, 2015
We consider two weakly interacting quasi-1D condensates of cold bosonic atoms. It turns out that a time-dependent variation of the tunnel-coupling between those condensates is equivalent to the spatial expansion of a one-dimensional toy-Universe, with ...

Light storage and control of photon-photon interactions in a cold Rydberg gas [PDF]

open access: yes, 2013
The effect of strong interatomic interactions on an optical field stored in Rydberg states of a cold atomic gas is investigated. Due to their large dipole moments Rydberg atoms interact very strongly with each other.

Optomechanical coupling between ultracold atoms and a membrane oscillator [PDF]

open access: yes, 2014
In this thesis, I report on the realization of a hybrid optomechanical system in which ultracold atoms are coupled to a micromechanical membrane. The atoms are trapped in the intensity maxima of an optical standing wave formed by retroreflection of a ...

Witness of non-Markovian dynamics based on Bhattacharyya quantum distance

open access: yesScientific Reports
Non-Markovian effects due to quantum memory in the dynamics of open systems typically correspond to information backflows from the surrounding environment to the system.

Engineering thermal reservoirs for ultracold dipole–dipole-interacting Rydberg atoms

open access: yesNew Journal of Physics, 2018
We consider an open quantum system of ultracold Rydberg atoms. The system part consists of resonant dipole–dipole-interacting Rydberg states. The environment part is formed by ‘three-level atoms’: each atom has a ground state, a short-lived excited state,

Does probabilism solve the great quantum mystery? [PDF]

open access: yes, 2004
What sort of entities are electrons, photons and atoms given their wave-like and particle-like properties? Is nature fundamentally deterministic or probabilistic?

QUANTUM REFLECTION AND THE INTERACTIONS OF ULTRACOLD ATOMS WITH SURFACES AND NANOSTRUCTURES

open access: yesMomento, 2011
Quantum reflection refers to the reflection of particles by attractive long-range potentials in nonclassical regions of coordinate space without reaching a classical turning point.
