Novel schemes for the optical manipulation of atoms and molecules [PDF]

open access: yes, 2009
The range of atoms which can be cooled by lasers is limited to those which have a closed two level structure. Several schemes have been proposed which aim to extend this range by using coherent control of the particle momenta, but none have yet been ...

Dynamical Thermalization of Interacting Fermionic Atoms in a Sinai Oscillator Trap

open access: yesCondensed Matter, 2019
We study numerically the problem of dynamical thermalization of interacting cold fermionic atoms placed in an isolated Sinai oscillator trap. This system is characterized by a quantum chaos regime for one-particle dynamics.

Realisation of a cold mixture of rubidium and caesium [PDF]

open access: yes, 2008
This thesis describes a new apparatus designed to study cold, ultracold, and quantum degenerate mixtures of rubidium and caesium atoms. The Rb- Cs mixture is prepared using a double magneto-optical trap (MOT) system in which a two-species pyramid MOT ...

Explicit large nuclear charge limit of electronic ground states for Li, Be, B, C, N, O, F, Ne and basic aspects of the periodic table [PDF]

open access: yes, 2009
This paper is concerned with the Schrödinger equation for atoms and ions with $N=1$ to 10 electrons. In the asymptotic limit of large nuclear charge $Z$, we determine explicitly the low-lying energy levels and eigenstates.

Many body effects in one-dimensional attractive Bose gases [PDF]

open access: yes, 2013
In this thesis we investigate the properties of ultra-cold quantum gases in reduced dimension and the effects of harmonic confinement on soliton-like properties.

Quantum phase transitions in an interacting atom-molecule boson model [PDF]

open access: yes, 2010
We study the quantum phase transitions of a model that describes the interconversion of interacting bosonic atoms and molecules. Using a classical analysis, we identify a threshold coupling line separating a molecular phase and a mixed phase.

Schwinger pair production with ultracold atoms

open access: yesPhysics Letters B, 2016
We consider a system of ultracold atoms in an optical lattice as a quantum simulator for electron–positron pair production in quantum electrodynamics (QED).

Strongly correlated ultracold bosons in an optical lattice [PDF]

open access: yes, 2012
In this thesis, we have investigated strongly correlated bosonic gases in an optical lattice, mostly based on a bosonic version of dynamical mean field theory and its real-space extension. Emphasis is put on possible novel quantum phenomena of these many-

Towards quantum simulating QCD [PDF]

open access: yes, 2014
Quantum link models provide an alternative non-perturbative formulation of Abelian and non-Abelian lattice gauge theories. They are ideally suited for quantum simulation, for example, using ultracold atoms in an optical lattice. This holds the promise to
