Matter-wave collimation to picokelvin energies with scattering length and potential shape control
Alexander Herbst, Timothé Estrampes, Henning Albers +7
The sensitivity of atom interferometers depends on their ability to realize long pulse separation times and prevent loss of contrast by limiting the expansion of the atomic ensembl…
A high-flux source system for matter-wave interferometry exploiting tunable interactions
Alexander Herbst, Timothé Estrampes, Henning Albers +7
Atom interferometers allow determining inertial effects to high accuracy. Quantum-projection noise as well as systematic effects impose demands on large atomic flux as well as ultr…
Rapid generation of all-optical K Bose-Einstein condensates using a low-field Feshbach resonance
Alexander Herbst, Henning Albers, Knut Stolzenberg +2
Ultracold potassium is an interesting candidate for quantum technology applications and fundamental research as it allows controlling intra-atomic interactions via low-field magnet…
All-Optical Matter-Wave Lens using Time-Averaged Potentials
H. Albers, R. Corgier, A. Herbst +11
The stability of matter-wave sensors benefits from interrogating large-particle-number atomic ensembles at high cycle rates. The use of quantum-degenerate gases with their low effe…
Quantum test of the Universality of Free Fall using rubidium and potassium
H. Albers, A. Herbst, L. L. Richardson +11
We report on an improved test of the Universality of Free Fall using a rubidium-potassium dual-species matter wave interferometer. We describe our apparatus and detail challenges a…
Evaporative cooling from an optical dipole trap in microgravity
Christian Vogt, Marian Woltmann, Henning Albers +4
In recent years, cold atoms could prove their scientific impact not only on ground but in microgravity environments such as the drop tower in Bremen, sounding rockets and parabolic…
Optomechanical resonator-enhanced atom interferometry
L. L. Richardson, D. Nath, A. Rajagopalan +16
Matter-wave interferometry and spectroscopy of optomechanical resonators offer complementary advantages. Interferometry with cold atoms is employed for accurate and long-term stabl…
Ground Tests of Einstein's Equivalence Principle: From Lab-based to 10-m Atomic Fountains
D. Schlippert, H. Albers, L. L. Richardson +10
To date, no framework combining quantum field theory and general relativity and hence unifying all four fundamental interactions, exists. Violations of the Einstein's equivalence p…
Quantum Test of the Universality of Free Fall
Dennis Schlippert, Jonas Hartwig, Henning Albers +6
We simultaneously measure the gravitationally-induced phase shift in two Raman-type matter-wave interferometers operated with laser-cooled ensembles of Rb and K atoms…
