Exploring Interacting Quantum Many-Body Systems by Experimentally Creating Continuous Matrix Product States in Superconducting Circuits

Physical Review X, 2015
Improving the understanding of strongly correlated quantum many-body systems such as gases of interacting atoms or electrons is one of the most important challenges in modern condensed matter physics, materials research, and chemistry.

Laser spectroscopic probing of coexisting superfluid and insulating states of an atomic Bose–Hubbard system

Nature Communications, 2016
A system of ultracold atoms in an optical lattice can be used as a quantum simulator for the Hubbard model with high controllability. Here, the authors report a laser spectroscopy study of an ytterbium ultracold bosonic gas across the weakly to strongly ...

A cold strontium Rydberg gas [PDF]

, 2011
Cold gases of Rydberg atoms are an ideal system in which to study the novel effects of strong interatomic interactions. This thesis describes the design and construction of the world's first experiment to study Rydberg states in a cold gas of an alkaline

Interfacing ultracold atoms with nanomagnetic domain walls [PDF]

, 2012
This thesis presents the first realisation of a new type of hybrid quantum device based on spintronic technology. We demonstrate an interaction between the magnetic fringing fields produced by domain walls within planar permalloy nanowires and a cloud of

Comment on 'A scattering quantum circuit for measuring Bell's time inequality:a nuclear magnetic resonance demonstration using maximally mixed states' [PDF]

, 2012
A recent paper by Souza, Oliveira and Sarthour (SOS) reports the experimental violation of a Leggett-Garg (LG) inequality (sometimes referred to as a temporal Bell inequality).

Quantum Markovian activated surface diffusion of interacting adsorbates [PDF]

, 2008
5 pags. ; 4 figs.A quantum Markovian activated atom-surface diffusion model with interacting adsorbates is proposed for the intermediate scattering function, which is shown to be complex-valued and factorizable into a classical-like and a quantum ...

Quantum Fisher information of N-level atoms under the influence of the thermal field and the Stark effect

AIP Advances
This study investigates the quantum features of quantum entanglement (QE) in N-level atomic systems interacting with the thermal state subjected to varying Stark shift (SS) parameters.
