For decades, hundreds of writers have developed analyses and conjectures about how Albert Einstein formulated his special theory of relativity of 1905. I will summarize and critique certain provocative and influential accounts, and will also describe neglected aspects of the process. Which experiments...

The presentation will concentrate on recent applications of Penning traps in atomic and nuclear physics with exotic ions, namely high-accuracy mass measurements of short-lived radionuclides, g-factor determinations of the bound-electron in highly-charged, hydrogen-like ions and g-factor measurements...

Bose-Einstein condensates (BEC’s) in a honeycomb optical lattice are described by a nonlinear Dirac equaton (NLDE) in the long wavelength, mean field limit [1].  The bipartite structure of the lattice appears as pseudospin in the multi-component BEC with states above and below the Dirac point...

We have recently proposed an experiment to cool to the ground state and create quantum superpositions of the center of mass motion of an optically levitating nanodielectric.  This can be achieved by exploiting the coupling between light and the mechanical motion, which is obtained when the object...
