Mesoscopic Spin-Boson Models of Trapped Ions
D. Porras, F. Marquardt, J. von Delft +1
Trapped ions arranged in Coulomb crystals provide us with the elements to study the physics of a single spin coupled to a boson bath. In this work we show that optical forces allow…

Measuring the size of a Schroedinger cat state
Florian Marquardt, Benjamin Abel, Jan von Delft
We propose a measure for the "size" of a Schroedinger cat state, i.e. a quantum superposition of two many-body states with (supposedly) macroscopically distinct properties, by coun…
