Adiabatic cooling of cesium to 700 nK in an optical lattice.
We localize Cs atoms in wavelength-sized potential wells of an optical lattice, and cool them to a three-dimensional temperature of 700 nK by adiabatic expansion. In the optical lattice we precool the atoms to ø1 mK. We then reduce the trapping potential in a few hundred ms, causing the atomic center-of-mass distribution to expand and the temperature to decrease by an amount which agrees with a...
متن کاملModulation spectroscopy with ultracold fermions in an optical lattice
We propose an experimental setup of ultracold fermions in an optical lattice to determine the pairing gap in a superfluid state and the spin ordering in a Mott-insulating state. The idea is to apply a periodic modulation of the lattice potential and to use the thereby induced double occupancy to probe the system. We show by full time-dependent calculation using the adaptive time-dependent densi...
متن کاملLocal dynamics of laser cooling in an optical lattice
Using the basis of Wannier states, we study the local dynamics of polarization gradient cooling for an atom driven on a Jg52→Je53 transition by a one-dimensional optical lattice. This analysis allows us to formulate a physical picture of the cooling mechanism, analogous to Sisyphus cooling for a Jg51/2→Je53/2 atom, which depends strongly on coherences in the Zeeman sublevels of the ground state...
متن کاملSuper-heavy electron material as metallic refrigerant for adiabatic demagnetization cooling
Low-temperature refrigeration is of crucial importance in fundamental research of condensed matter physics, because the investigations of fascinating quantum phenomena, such as superconductivity, superfluidity, and quantum criticality, often require refrigeration down to very low temperatures. Currently, cryogenic refrigerators with (3)He gas are widely used for cooling below 1 K. However, usag...
متن کاملFermions in 3D optical lattices: cooling protocol to obtain antiferromagnetism.
A major challenge in realizing antiferromagnetic and superfluid phases in optical lattices is the ability to cool fermions. We determine the equation of state for the 3D repulsive Fermi-Hubbard model as a function of the chemical potential, temperature, and repulsion using unbiased determinantal quantum Monte Carlo methods, and we then use the local density approximation to model a harmonic tra...
