Long-range fiber-optic earthquake sensing by active phase noise cancellation
Sebastian Noe, Dominik Husmann, Nils Müller +2
We present a long-range fiber-optic environmental deformation sensor based on active phase noise cancellation (PNC) in metrological frequency dissemination. PNC sensing exploits re…
SI-traceable frequency dissemination at 1572.06 nm in a stabilized fiber network with ring topology
Dominik Husmann, Laurent-Guy Bernier, Mathieu Bertrand +18
Frequency dissemination in phase-stabilized optical fiber networks for metrological frequency comparisons and precision measurements are promising candidates to overcome the limita…
Quantized conductance through a dissipative atomic point contact
Laura Corman, Philipp Fabritius, Samuel Häusler +5
Signatures of quantum transport are expected to quickly vanish as dissipation is introduced in a system. This dissipation can take several forms, including that of particle loss, w…
Quantized conductance through a spin-selective atomic point contact
Martin Lebrat, Samuel Häusler, Philipp Fabritius +3
We implement a microscopic spin filter for cold fermionic atoms in a quantum point contact (QPC) and create fully spin-polarized currents while retaining conductance quantization.…
Breakdown of the Wiedemann-Franz law in a unitary Fermi gas
Dominik Husmann, Martin Lebrat, Samuel Häusler +3
We report on coupled heat and particle transport measurements through a quantum point contact (QPC) connecting two reservoirs of resonantly interacting, finite temperature Fermi ga…
Band and correlated insulators of cold fermions in a mesoscopic lattice
Martin Lebrat, Pjotrs Grišins, Dominik Husmann +5
We investigate the transport properties of neutral, fermionic atoms passing through a one-dimensional quantum wire containing a mesoscopic lattice. The lattice is realized by proje…
A scanning gate microscope for cold atomic gases
Samuel Häusler, Shuta Nakajima, Martin Lebrat +4
We present a scanning probe microscopy technique for spatially resolving transport in cold atomic gases, in close analogy with scanning gate microscopy in semiconductor physics. Th…
Mapping out spin and particle conductances in a quantum point contact
Sebastian Krinner, Martin Lebrat, Dominik Husmann +3
We study particle and spin transport in a single mode quantum point contact using a charge neutral, quantum degenerate Fermi gas with tunable, attractive interactions. This yields…
Connecting strongly correlated superfluids by a quantum point contact
Dominik Husmann, Shun Uchino, Sebastian Krinner +4
Point contacts provide simple connections between macroscopic particle reservoirs. In electric circuits, strong links between metals, semiconductors or superconductors have applica…
Observation of Quantized Conductance in Neutral Matter
Sebastian Krinner, David Stadler, Dominik Husmann +2
In transport experiments the quantum nature of matter becomes directly evident when changes in conductance occur only in discrete steps, with a size determined solely by Planck's c…
