A new degenerate Fermi gas apparatus
… MIT started a new research direction of studying degenerate fermionic Lithium atoms in optical lattices. The major contributions to the new experimental setup are the Lithium laser system, a new imaging technique, and an advanced experiment control system. First, a tapered amplifier laser diode …

Geometric Squeezing of a Degenerate Fermi Gas
Quantum simulation with ultracold gases provides a highly customizable platform for the study of many-body physics, shedding new light on important physical systems. Magnetic fields or, equivalently in the case of a uniform, static field, rotation are especially important parameters for many-body …

Quark masses : an environmental impact statement
… Weizsacker semi-empirical mass formula through a degenerate Fermi gas model that handles the kinetic energy of new baryonic species as they begin to participate in the nucleus, and derive an expression for the asymmetry energy equivalent in the SU(3) limit through a minimization procedure on the …

Single-atom imaging of 40K atoms via raman sideband cooling
… thesis is the trapping, cooling and imaging of fermionic potassium atoms in optical lattice potentials. Our experiment is capable of cooling 40K atoms to a T /TF of 0.18, well into the degenerate Fermi-gas regime. We then load the atoms into a 3D optical lattice and prepare ∼ 500 atoms in one …

A next-generation apparatus for lithium optical lattice experiments
… matter systems, in particular the physics of the Fermi-Hubbard model, using ultracold Lithium atoms in an optical lattice. A major goal of the quantum simulation program is to observe phase transitions of the Hubbard model, into Néel antiferromagnetic phases and d-wave superfluid phases. Phase …

From quarks to cold atoms: the phases of strongly-interacting systems
… and quark stars, and the phases of ultracold fermions in the presence of an artificial spin-orbit coupling. While spanning an extraordinary twenty orders of magnitude in energy scales, these systems exhibit some remarkable similarities including non-perturbative many-body interactions, perfect …

Pairing and entanglement: quantum Monte Carlo studies
… is used to model a one-dimensional system of fermionic lithium atoms according to existing experiments, including a realistic temperature. New estimators of the pair momentum distribution are implemented, yielding in a clear in-situ signature of a pairing mechanism (dubbed FFLO after its first …
