Monolithic atom interferometry
Johannes Fiedler, Kim Lefmann, Wolf von Klitzing +1
Atom and, more recently, molecule interferometers are used in fundamental research and industrial applications. Most atom interferometers rely on gratings made from laser beams, wh…
Quantum Technologies in Space
Rainer Kaltenbaek, Antonio Acin, Laszlo Bacsardi +17
Recently, the European Commission supported by many European countries has announced large investments towards the commercialization of quantum technology (QT) to address and mitig…
Matter-wave interferometers using TAAP rings
Patrick Navez, Saurabh Pandey, Hector Mas +3
We present two novel matter-wave Sagnac interferometers based on ring- shaped time-averaged adiabatic potentials (TAAP). For both the atoms are put into a superposition of two diff…
STE-QUEST - Test of the Universality of Free Fall Using Cold Atom Interferometry
D. Aguilera, H. Ahlers, B. Battelier +63
The theory of general relativity describes macroscopic phenomena driven by the influence of gravity while quantum mechanics brilliantly accounts for microscopic effects. Despite th…
Spontaneous emergence of angular momentum Josephson oscillations in coupled annular Bose-Einstein condensates
Igor Lesanovsky, Wolf von Klitzing
We investigate the nonlinear dynamics of two coupled annular Bose-Einstein condensates (BECs). For certain values of the coupling strength the nonrotating ground state is unstable…
Tunable whispering gallery modes for spectroscopy and CQED experiments
Wolf von Klitzing, Romain Long, Vladimir S. Ilchenko +2
We have tuned the whispering gallery modes of a fused silica micro- resonator over nearly 1 nm at 800 nm, i.e.over half of a free spectral range or the equivalent of 10^6 linewidth…
Frequency tuning of the whispering gallery modes of silica microspheres for CQED and spectroscopy
Wolf von Klitzing, Romain Long, Vladimir S. Ilchenko +2
We have tuned the whispering gallery modes of a fused silica microresonator over nearly 1 nm at 800 nm, i.e. over 0.5 FSR or 10^6 linewidths of the resonator. This has been achieve…
