Four-Dimensional Quantum Hall Effect with Ultracold Atoms.

Abstract: We propose a realistic scheme to detect the 4D quantum Hall effect using ultracold atoms. Based on contemporary technology, motion along a synthetic fourth dimension can be accomplished through controlled transitions between internal states of atoms arranged in a 3D optical lattice. From a semiclassical analysis, we identify the linear and nonlinear quantized current responses of our 4D model, relating these to the topology of the Bloch bands. We then propose experimental protocols, based on current or center-of-mass-drift measurements, to extract the topological second Chern number. Our proposal sets the stage for the exploration of novel topological phases in higher dimensions.

Knowing and learning in practice‐based studies: an introduction

Abstract: Purpose – The aim of this introduction to the special issue is to furnish a panorama on how practice‐based studies (PBS) concerned with organizational learning have developed in recent years, and to describe the topics that such studies have debatedDesign/methodology/approach – The articles in this special issue were first presented at the standing working group on “Practice‐based Studies of Knowledge and Innovation in Workplaces” of the European Group for Organizational Studies, and will therefore provide the background to PBS and an idea of its methodologyFindings – The practice‐ based approach may be useful for: a renewed conception of organization as a texture of interrelated practices which extend to form an action‐net sustained by a knowing‐in‐action which renews itself and transforms itself into being practiced; a renewed conception of knowledge as a situated, negotiated, emergent and embedded activity; a renewed conception of materiality as a form of distributed agency and an intimate relationsh

Fermionized Photons in an Array of Driven Dissipative Nonlinear Cavities

Abstract: We theoretically investigate the optical response of a one-dimensional array of strongly nonlinear optical microcavities. When the optical nonlinearity is much larger than both losses and intercavity tunnel coupling, the nonequilibrium steady state of the system is reminiscent of a strongly correlated Tonks-Girardeau gas of impenetrable bosons. Signatures of strong correlations are identified in the transmission spectrum of the system, as well as in the intensity correlations of the transmitted light. Possible experimental implementations in state-of-the-art solid-state devices are discussed.
