Integrable active atom interferometry
Michael Kastner, Vincent Menet, Johannes N. Kriel
Active interferometers are designed to enhance phase sensitivity beyond the standard quantum limit by generating entanglement inside the interferometer. An atomic version of such a…

Ancilla-assisted probing of temporal quantum correlations of large spins
Michael Kastner
When measuring quantum spins at two or more different times, the later measurements are affected by measurement backaction occurring due to the earlier measurements. This makes the…

Bosonic representation of a Lipkin-Meshkov-Glick model with Markovian dissipation
Jan C. Louw, Michael Kastner, Johannes N. Kriel
We study the dynamics of a Lipkin-Meshkov-Glick model in the presence of Markovian dissipation, with a focus on late-time dynamics and the approach to thermal equilibrium. Making u…
