Positronium Laser Deceleration, Cooling and Trapping
Barna Mendei, Helmut Ritsch
We numerically study laser deceleration, cooling and trapping of host fast ortho-positronium (Ps) bunches as produced in silica microchannel targets using positron bunches from a S…
Tunable-Size Unruh-DeWitt Detector in a Multimode Cavity
Simon Brunner, Farokh Mivehvar, Helmut Ritsch +1
Quantum simulators based on Bose-Einstein condensates (BECs) provide a powerful platform to study relativistic quantum-field phenomena in the lab and in particular emulate relativi…
Synthesizing variable particle interaction potentials via spectrally shaped spatially coherent illumination
Daniela Holzmann, Matthias Sonnleitner, Helmut Ritsch
Collective scattering of spatially coherent radiation by separated point emitters induces inter-particle forces. For particles close to nano-photonic structures as, for example, na…
Probing and characterizing the growth of a crystal of ultracold bosons and light
Stefan Ostermann, Francesco Piazza, Helmut Ritsch
The non-linear coupled particle light dynamics of an ultracold gas in the field of two independent counter-propagating laser beams can lead to the dynamical formation of a self-ord…
Tailored long range forces on polarizable particles by collective scattering of broadband radiation
Daniela Holzmann, Helmut Ritsch
Collective coherent light scattering by polarizable particles creates surprisingly strong, long range inter-particle forces originating from interference of the light scattered by…
Laser noise imposed limitations of ensemble quantum metrology
David Plankensteiner, Johannes Schachenmayer, Helmut Ritsch +1
Laser noise is a decisive limiting factor in high precision spectroscopy of narrow lines using atomic ensembles. In an idealized Doppler and differential light shift free magic wav…
