This paper is a short introduction to cold atom physics and Bose-Einstein condensation. Light forces on atoms are presented, together with laser cooling, and a few atom traps: the magneto-optical trap, dipole traps and magnetic traps. A brief description of Bose-Einstein condensation is given together with some important links with condensed matter physics. The reader is referred to comprehensive reviews and to other lecture notes for further details on atom cooling, trapping and Bose-Einstein…

Non-adiabatic losses from radio frequency dressed cold atom traps

Cold atom traps are a promising tool for investigating and manipulating atomic behaviour. Radio frequency (RF) dressed cold atom traps allow high versatility of trapping potentials, which is…

Optical lattice clocks, which were first imagined in 2000, should allow to achieve unprecedented performances in the domain of atomic clocks. We first discuss here the principle of operation of these…

Topics in quantum measurement of many-body systems

In quantum physics, measurement exhibits fundamentally different behaviour to the classical case, having direct effect on the observed system. As a result, the very act of observation in quantum…

Measuring out-of-time-ordered correlation functions with a single impurity qubit in a bosonic Josephson junction

We calculate the out-of-time-ordered correlation function (OTOC) of a single impurity qubit coupled to a fully connected many-particle system, such as a bosonic Josephson junction, or spins with…

Localisation of weakly interacting bosons in two dimensions: disorder vs lattice geometry effects

The results show a smooth transition, or crossover, to localisation induced by disorder in square and triangular lattices, and conclude that the coordination number z have a partial influence on how fast this smooth transition occurs as the system size increases.

Multi-parameter optimisation of quantum optical systems

Quantum optical systems are poised to become integral components of technologies of the future. While there is growing commercial interest in these systems—for applications in information processing,…

Pulse train uniformity and nonlinear dynamics of soliton crystals in mode-locked fiber ring lasers

The evolution of soliton crystal structures is analytically and numerically investigated in passively mode-locked fiber lasers by means of the nonlinear rotation of polarization. Four parameters are…

False signals of chaos from quantum probes

We demonstrate that two-time correlation functions, which are generalizations of out-of-timeordered correlators (OTOCs), can show ‘false-flags’ of chaos by exhibiting behaviour predicted by random…
