While inhomogeneous diffusivity has been identified as a ubiquitous feature of the cellular interior, its implications for particle mobility and concentration at different length scales remain largely unexplored. In this work, we use agent-based simu

We report the experimental study of a harmonic oscillator in the relativistic regime. The oscillator is composed of Bose-condensed lithium atoms in the third band of an optical lattice, which have an energy–momentum relation nearly identical to tha

A particle in an Anderson-localized system, if launched in any direction, should, on average, return to its starting point and stay there. Despite the central role played by Anderson localization in the modern understanding of condensed matter, this

There is a close theoretical correspondence between the ultrafast dynamics of bound electrons and the slow dynamics of trapped ultracold atoms. Here the authors exploit this mapping to experimentally simulate ultrafast phenomena with a large temporal

We report an experimental study investigating transport phenomena of ultracold atoms loaded in a primary optical lattice and periodically-kicked with an incommensurate optical lattice. We observe signatures of an extended multifractal phase.

We have built an ultra-high vacuum experimental apparatus for trapping and cooling of strontium, demonstrated its operation, and used it to trap and cool all four stable isotopes of this alkaline earth metal. As part of the design and construction of

Can quantum mechanical thermodynamic engines outperform their classical counterparts? To address one aspect of this question, we experimentally realize and characterize an isentropic thermodynamic engine that uses a Bose-condensed working fluid. In t
