Many-body physics with ultracold gases

I Bloch, J Dalibard, W Zwerger - Reviews of modern physics, 2008‏ - APS
This paper reviews recent experimental and theoretical progress concerning many-body
phenomena in dilute, ultracold gases. It focuses on effects beyond standard weak-coupling …

Localization of bosonic atoms by fermionic impurities in a three-dimensional optical lattice

S Ospelkaus, C Ospelkaus, O Wille, M Succo, P Ernst… - Physical review …, 2006‏ - APS
We observe a localized phase of ultracold bosonic quantum gases in a 3-dimensional
optical lattice induced by a small contribution of fermionic atoms acting as impurities in a …

Free fermion antibunching in a degenerate atomic Fermi gas released from an optical lattice

T Rom, T Best, D Van Oosten, U Schneider, S Fölling… - Nature, 2006‏ - nature.com
Noise in a quantum system is fundamentally governed by the statistics and the many-body
state of the underlying particles,,,. The correlated noise,, observed for bosonic particles (for …

Species-specific optical lattices

LJ LeBlanc, JH Thywissen - Physical Review A—Atomic, Molecular, and …, 2007‏ - APS
We examine single-frequency optical schemes for species-selective trap** of ultracold
alkali-metal atoms. Independently addressing the elements of a binary mixture enables the …

Rotation of quantum impurities in the presence of a many-body environment

R Schmidt, M Lemeshko - Physical review letters, 2015‏ - APS
We develop a microscopic theory describing a quantum impurity whose rotational degree of
freedom is coupled to a many-particle bath. We approach the problem by introducing the …

Collective excitations of a Bose–Einstein condensate of hard-core bosons and their mediated interactions: from two-body bound states to mediated superfluidity

M Santiago-García… - New Journal of …, 2023‏ - iopscience.iop.org
The exchange of collective modes has been demonstrated to be a powerful tool for inducing
superconductivity and superfluidity in various condensed matter and atomic systems. In this …

Cold atoms and molecules in self-assembled dipolar lattices

G Pupillo, A Griessner, A Micheli, M Ortner, DW Wang… - Physical review …, 2008‏ - APS
We study the realization of lattice models, where cold atoms and molecules move as extra
particles in a dipolar crystal of trapped polar molecules. The crystal is a self-assembled …

Quantum Monte Carlo and perturbative study of two-dimensional Bose-Fermi mixtures

J D'Alberto, L Cardarelli, DE Galli, G Bertaina, P Pieri - Physical Review A, 2024‏ - APS

equation of state and to the fermionic quasiparticle residue and effective mass of a dilute …

Majorana modes and p-wave superfluids for fermionic atoms in optical lattices

A Bühler, N Lang, CV Kraus, G Möller, SD Huber… - Nature …, 2014‏ - nature.com
The quest for realization of non-Abelian phases of matter, driven by their possible use in
fault-tolerant topological quantum computing, has been spearheaded by recent …

-wave superfluidity of atomic lattice fermions

AK Fedorov, VI Yudson, GV Shlyapnikov - Physical Review A, 2017‏ - APS
We discuss the emergence of p-wave superfluidity of identical atomic fermions in a two-
dimensional optical lattice. The optical lattice potential manifests itself in an interplay …
