Atoms in Optical Lattices

J.-Y. Courtois, G. Grynberg

Published Jan 1, 1996• 2 citations
Publisher

Abstract

Recent fundamental results demonstrate that it should be possible to probe concepts developed for condensed matter at totally different scales using optical lattices, where the defect-free confining potential is created by light interference.

Excitation-induced defects in photonic band gaps in a lattice Bose-Einstein condensate

Karl-Peter Marzlin, Weiping Zhang

Summary form only given. Recent research is rapidly moving toward all-optical confinement of Bose-Einstein condensate (BEC) in optical traps. The optical trap provides an effective tool to manipulate the dynamics of BEC for practical purposes. In particular it opens the possibilities to study BEC in an optical lattice. In this work, we focus on studying the properties of propagation of a weak probe light through a BEC confined in an optical lattice. The key point in the topic is that the ground state of the lattice BEC acts as a periodic dielectric medium for the probe light propagating through it. We show that photonic, or rather polaritonic band gaps are created for probe light due to the spatial periodicity of the ground state of the lattice BEC. However being different from the ordinary periodic dielectric, the lattice BEC can experience elementary excitations which lead to a perturbative distortion of the periodicity of the lattice BEC. Such non-periodic perturbations are similar to lattice defects in solid state physics. Here they will produce defect states inside the photonic band gaps. By analyzing the elementary excitations of the lattice BEC, we study the frequency spectrum of photonic band gaps and defect states induced by such excitations in the lattice BEC. These photonic defect states may technically have the potential to be employed to acquire knowledge about the quantum degeneracy in an optical lattice.

Quantum simulation of quantum many-body systems with ultracold two-electron atoms in an optical lattice

Yoshiro Takahashi

Ultracold atoms in an optical lattice provide a unique approach to study quantum many-body systems, previously only possible by using condensed-matter experimental systems. This new approach, often called quantum simulation, becomes possible because of the high controllability of the system parameters and the inherent cleanness without lattice defects and impurities. In this article, we review recent developments in this rapidly growing field of ultracold atoms in an optical lattice, with special focus on quantum simulations using our newly created quantum many-body system of two-electron atoms of ytterbium. In addition, we also mention other interesting possibilities offered by this novel experimental platform, such as applications to precision measurements for studying fundamental physics and a Rydberg atom quantum computation.

Quantum criticality in ultracold atoms on optical lattices

Marcos Rigol, Alejandro Muramatsu

Abstract In recent years degenerate quantum gases confined in optical lattices developed as a new field of research bridging the areas of quantum optics, atomic physics, and condensed matter physics. It offers the possibility of manipulating quantum many‐body systems with an unprecedented flexibility, so that they can be considered as analog simulators of condensed matter systems. Particularly interesting is the possibility of creating strongly correlated bosonic or fermionic systems. We review here recent numerical simulations, where quantum critical behavior is studied both in and out of equilibrium. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
