We propose a method of using off-resonant light scattering to measure the temperature of fermionic atoms tightly confined in a two-dimensional optical-lattice potential. We show that fluctuations of the intensity in the far-field diffraction pattern arising from thermal correlations of the atoms can be accurately detected above the shot noise by collecting photons scattered in a forward direction, with the diffraction maxima blocked. The sensitivity of this method of thermometry is enhanced by…

Off-resonant light scattering from ultracold gases in optical lattices

We examine the possibility to study the statistical properties of trapped ultracold bosons with light scattering. We derive general effective hamiltonian and show that the spectrum of scattered

Thermometry of Cold Atoms in Optical Lattices via Demixing

Motivated by recent experiments and theoretical investigations on binary mixtures, we investigate the miscible-immiscible transition at finite temperature by means of Quantum Monte Carlo. Based on

Superlattice Modulation Spectroscopy of Ultracold Atoms in Optical Lattices

We study the influence of a periodic superlattice modulation onto bosonic and fermionic atoms trapped in an optical lattice. The superlattice modulation is applied along one direction and injects

Few-fermion thermometry

Potential realization of a quantum thermometer operating in the nanokelvin regime, formed by a few-fermionic mixture confined in a one-dimensional harmonic trap, is proposed. Thermal states of the

Spatial Pauli blocking of spontaneous emission in optical lattices

Spontaneous emission by an excited fermionic atom can be suppressed due to the Pauli exclusion principle if the relevant final states after the decay are already occupied by identical atoms in the

Thermometry of bosonic mixtures in Optical Lattices via Demixing

It is shown that the proposed method for demixing for thermometry of a binary bosonic mixture trapped in an optical lattice is especially sensitive at low temperatures, of the order of the tunnelling amplitude, and therefore is particularly suitable in the regime where quantum magnetism is expected.

Single-Atom Resolved Imaging and Manipulation in an Atomic Mott Insulator

This thesis reports on new experimental techniques for the study of strongly correlated states of ultracold atoms in optical lattices. We used a high numerical aperture imaging system to probe 87Rb

Homodyne detection of matter-wave fields

A scheme is discussed that allows one for performing homodyne detection of the matter-wave field of ultracold bosonic atoms. It is based on a pump-probe lasers setup, that both illuminates a

Physics of our Days: Cooling and thermometry of atomic Fermi gases

We review the status of cooling techniques aimed at achieving the deepest quantum degeneracy for atomic Fermi gases. We first discuss some physics motivations, providing a quantitative assessment of

Cavity quantum electrodynamics of continuously monitored Bose-condensed atoms

We study cavity quantum electrodynamics of Bose-condensed atoms that are subjected to continuous monitoring of the light leaking out of the cavity. Due to a given detection record of each stochastic
