Ultracold atomic gases in optical lattices: mimicking condensed matter physics and beyond [PDF]

, 2007
We review recent developments in the physics of ultracold atomic and molecular gases in optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard models, and as such may very well serve to mimic condensed matter phenomena.

Bose–Einstein condensation of 162Dy and 160Dy

New Journal of Physics, 2015
We report Bose–Einstein condensation of two isotopes of the highly magnetic element dysprosium: ^162 Dy and $^{160}$ Dy. For ^162 Dy, condensates with 10 ^5 atoms form below T = 50 nK. We find the evaporation efficiency for the isotope ^160 Dy to be poor;

Optimal control of Bose–Einstein condensates in three dimensions

New Journal of Physics, 2015
Ultracold gases promise many applications in quantum metrology, simulation and computation. In this context, optimal control theory (OCT) provides a versatile framework for the efficient preparation of complex quantum states.

Dark resonances for ground state transfer of molecular quantum gases [PDF]

, 2008
One possible way to produce ultracold, high-phase-space-density quantum gases of molecules in the rovibronic ground state is given by molecule association from quantum-degenerate atomic gases on a Feshbach resonance and subsequent coherent optical multi ...

Lee-Huang-Yang effects in the ultracold mixture of ^{23}Na and ^{87}Rb with attractive interspecies interactions

Physical Review Research, 2021
The beyond-mean-field Lee-Huang-Yang (LHY) correction is ubiquitous in dilute ultracold quantum gases. However, its effects are often elusive due to the typically much larger influence of the mean-field (MF) energy.

Quantum optics with ultracold quantum gases: towards the full quantum regime of the light–matter interaction [PDF]

, 2012
Although the study of ultracold quantum gases trapped by light is a prominent direction of modern research, the quantum properties of light were widely neglected in this field.

Quantum gas microscopy of ytterbium: cool me twice

New Journal of Physics, 2016
The site-resolved detection of ultracold atoms in optical lattice potentials is a powerful technique to study lattice models of correlated quantum matter. In their recent paper, Yamamoto et al (2016 New J. Phys.

Laser Cooling of Lanthanides: from Optical Clocks to Quantum Simulators

EPJ Web of Conferences, 2015
We discuss current progress in laser cooling of lanthanides (Er, Yb, Dy, Tm etc.) focusing on applications. We describe some important peculiarities taking Thulium atom as an example: Two stage laser cooling, trapping in an optical lattice, anisotropic ...

Ultra-cold single-atom quantum heat engines

New Journal of Physics, 2019
We propose a scheme for a single-atom quantum heat engine based on ultra-cold atom technologies. Building on the high degree of control typical of cold atom systems, we demonstrate that three paradigmatic heat engines—Carnot, Otto and Diesel—are within ...

Transport, atom blockade and output coupling in a Tonks-Girardeau gas [PDF]

, 2011
Recent experiments have demonstrated how quantum-mechanical impurities can be created within strongly correlated quantum gases and used to probe the coherence properties of these systems [S. Palzer, C. Zipkes, C. Sias, and M. K\"ohl, Phys. Rev. Lett. 103,
